Smart Shelf Safety Monitoring System SolutionPrevent Shelf Collapse, Ensure Personnel and Cargo Safety Structural Stability Monitoring: Shelf tilting may result from foundation settlement, overloading, forklift collisions, or long-term uneven stress. If not addressed promptly, it may lead to collapse accidents.Early Warning: Slight tilting is hard to detect with the naked eye, but through tilt sensors or regular inspections, potential hazards can be identified in advance to avoid catastrophic consequences.Avoid Cargo Sliding or Damage Center of Gravity Balance: Shelf tilting causes cargo center of gravity to shift, especially for high-level shelves or heavy goods, which can easily lead to sliding or tipping, causing cargo damage or even personnel injury.Special Cargo Protection: Precision instruments, fragile items (e.g., glass, electronics) have higher requirements for shelf levelness; even slight tilting may cause packaging damage or product breakage.Adapt to Automated Warehouse Systems (e.g., AGV/Stacker Crane) Precise Positioning Requirement: Automated warehouses rely on standard shelf arrangement; if tilting exceeds the allowable range (e.g., ±0.5°), it may cause stacker crane picking failures or collisions.System Linkage: Real-time tilt data can be fed back to the Warehouse Management System (WMS) to automatically adjust robot paths or pause operations in hazardous areas.Comply with Safety Regulations and Industry Standards Legal Requirements: Regulations such as OSHA (Occupational Safety and Health Administration, USA) and GB/T Code for the Use of Storage Shelves require regular inspection of shelf structures; if tilt exceeds limits, shelves must be taken out of service for repair.Insurance and Liability: Some insurers require enterprises to install tilt monitoring devices; otherwise, claims may be denied after an accident.Reduce Maintenance Costs, Extend Shelf Lifespan Preventive Maintenance: By monitoring tilt changes, determine whether to reinforce footings, adjust beams, or replace damaged components — preventing minor issues from escalating into major repairs.Reduce Downtime Loss: Sudden collapse can halt warehouse operations; regular inspections maximize operational continuity.Total Function of SystemTilt detection requires a complete system to ensure data usability. Our company has developed a full set of tilt monitoring system, which consists of front-end sensor inclinometers, wireless transmission, alarm terminals, mobile apps, and cloud platforms.

Smart Shelf Safety Inspection SolutionIndustry LandscapeIn logistics facilities, shelving units are typically tall, densely packed with heavy inventory, and require year-round real-time tilt monitoring to achieve the following objectives:Prevent Shelf Collapse and Ensure Personnel and Cargo SafetyStructural Stability Monitoring: Shelf tilting can result from foundation settlement, overloading, forklift collisions, or long-term uneven stress distribution. If left unaddressed, this may lead to catastrophic collapse.Early Warning: Minor tilts are often imperceptible to the naked eye; however, utilizing tilt sensors or regular inspections enables early detection of potential hazards, preventing disastrous outcomes.Prevent Cargo Sliding or DamageCenter-of-Gravity Balance: Tilted shelves cause cargo to shift off-center—particularly on high-level racks or with heavy loads—significantly increasing the risk of sliding, toppling, cargo damage, and even personnel injury.Specialized Cargo Protection: Precision instruments and fragile goods (e.g., glass, electronics) demand higher shelf levelness; even slight tilting can result in packaging damage or product defects.Compatibility with Automated Storage Systems (e.g., AGVs/Stacker Cranes)Precision Positioning Requirements: Automated warehouses rely on standardized rack alignment. If tilt exceeds permissible limits (e.g., ±0.5°), stacker cranes may fail to retrieve goods or risk collision.System Integration: Real-time tilt data can be fed back to the Warehouse Management System (WMS) to automatically adjust robotic pathways or suspend operations in hazardous zones.Compliance with Safety Regulations and Industry StandardsLegal Requirements: Standards such as OSHA (Occupational Safety and Health Administration) and GB/T Code for Use of Storage Shelves mandate regular structural inspections; racks exceeding tilt thresholds must be taken offline for repair.Insurance and Liability: Some insurers require the installation of tilt monitoring devices; otherwise, claims may be denied following an incident.Reduce Maintenance Costs and Extend Rack LifespanPreventive Maintenance: Monitoring tilt variations helps determine the need for footing reinforcement, beam adjustment, or replacement of damaged components, preventing minor issues from escalating into major repairs.Minimize Downtime Losses: Sudden collapses can halt warehouse operations, whereas routine inspections maximize operational continuity. Shelf tilt monitoring is a low-cost, high-return safety measure in logistics warehouse management, and it is particularly critical for high-bay racks, automated warehouses, or high-frequency operational environments. Leveraging IoT technology, our company has developed an unmanned shelf tilt monitoring system that significantly reduces accident risks and ensures the stable operation of storage systems through continuous IoT-based inspection.Tilt Monitoring SystemOverall System FunctionTilt detection requires a complete system to ensure the usability of the data. Our company has developed a full-fledged tilt monitoring system comprising front-end tilt sensors, wireless transmission modules, alarm terminals, a mobile app, and a cloud platform. The following sections will introduce the wireless transmission modules, alarm terminals, cloud platform, and tilt sensors respectively. Below is the system architecture diagram.The entire system operates as follows: One tilt sensor is installed on each shelf, powered either by battery or via constant power supply. Data transmission supports LoRa, LoRaWAN, or Wi-Fi. A display terminal is placed at the front of each rack group to visually indicate the tilt status of that specific group.2.2 Wireless TransmissionThis system employs three wireless transmission technologies: LoRa/LoRaWAN, Wi-Fi, and Cat1 (4G). Each is tailored to distinct deployment scenarios. LoRa/LoRaWAN is suited for large-scale localized environments—such as logistics shelving—where sensors require low power consumption, long-range transmission, and centralized management. Wi-Fi is ideal for settings with existing Wi-Fi coverage and no stringent power constraints. Cat1 (4G) targets highly dispersed, expansive environments, such as communication towers or structurally compromised buildings.

Mushroom House Temperature and Humidity Management SolutionI. Background and Core RequirementsMushrooms (such as shiitake, oyster, and enoki mushrooms) are highly sensitive to environmental conditions throughout their growth cycle—including the mycelium stage, primordium formation stage, and fruiting body development stage. Traditional mushroom house management relies on manual inspections, which often result in uneven temperature and humidity distribution, delayed parameter adjustments, uncontrolled CO₂ levels, and imprecise lighting. These issues can lead to high deformity rates, low survival rates, and inconsistent batch quality. Addressing current industry pain points and leveraging our product portfolio—which includes illuminance sensors, temperature and humidity sensors, carbon dioxide sensors, and a cloud platform—this solution focuses on four core requirements: precise monitoring, real-time alerts, intelligent control, and data traceability, effectively resolving the following key challenges:Temperature and Humidity Instability: Significant temperature and humidity variations exist across different zones of the mushroom house (e.g., shelf tiers, floor level, and ventilation outlets). For instance, shiitake mushrooms require 15–18°C and 85–90% humidity during the primordium stage—conditions that are difficult to regulate promptly through manual intervention.CO₂ Imbalance: Mushroom respiration generates CO₂. Excessively high concentrations (>1500 ppm) inhibit fruiting body development, while levels that are too low (<500 ppm) impair mycelial metabolism. Traditional monitoring lacks real-time data support.Inadequate Lighting: The mycelium stage requires darkness (<50 lux), whereas the fruiting body stage needs low light (50–500 lux). Manually operating supplemental lighting often results in deviations from target illumination levels.Lack of Data Traceability: The absence of historical environmental records prevents post-analysis and optimization of growth issues across different batches, leading to low efficiency in large-scale management.II. Solution Design PrinciplesPrecision Monitoring: Sensors are deployed in core growth zones of the mushroom house (e.g., middle tiers of cultivation shelves, dead corners of ventilation, and lighting areas) to ensure comprehensive, gap-free data coverage.Real-Time Alerts: Dynamic thresholds are configured (adjustable by mushroom variety and growth stage). When values exceed limits, the cloud platform instantly pushes SMS and app notifications to prevent delays.Intelligent Management: The cloud platform aggregates multi-dimensional data and supports automatic generation of growth reports to assist cultivation decision-making.Scalable Adaptation: Interfaces for smart devices (e.g., humidifiers, exhaust fans, supplemental lights) are reserved, enabling future upgrades to an integrated "monitoring-control" system.III. Core Solution Architecture (Layered Design)This solution adopts a four-tier architecture—Perception Layer, Transmission Layer, Platform Layer, and Application Layer—deeply integrating sensors with the cloud platform to achieve end-to-end environmental management of the mushroom house:Perception Layer: Environmental Data Acquisition Terminals (Core Product Implementation)As the primary data source, sensors are precisely deployed according to the spatial layout of the mushroom house and growth requirements, focusing on solving the issue of "data acquisition accuracy":Temperature and Humidity Sensors: Deployed at a density of one sensor per 50 m², prioritizing installation at the middle tier of cultivation shelves (core growth zone), floor level (to prevent water accumulation from high humidity), and ventilation outlets (to monitor intake and exhaust air conditions). High-humidity-adapted models are selected (measurement range: temperature 0–60°C, humidity 0–100% RH) to withstand the moist environment of mushroom housesHere's the English translation in plain text for you to copy:Wireless Temperature and Humidity SensorProduct FunctionUsed to monitor temperature and humidity in the mushroom house (fruiting room).

Solution for Wireless Temperature Monitoring Online System in Winery CellarsAutomated Brewing Environment DetectionI. Functional Requirements1. The Importance of Temperature and Air Quality in BrewingGenerally, the production of wine involves the following steps: raw material selection, starter culture preparation (Qu), fermentation, distillation, aging, blending, and bottling. From grain fermentation and distillation to aging and final bottling, temperature control is extremely critical.Brewing equipment, starter cultures (Jiuqu), and brewing techniques are often regarded as the "favorable climate, geographical advantage, and human unity" (Tian Shi, Di Li, Ren He) in the brewing industry. In this context, "geographical advantage" also refers to the environment—specifically the fermentation temperature and the air quality of the surroundings. Neglecting any of these three aspects will significantly compromise the quality of the final brew.Throughout the brewing process—from the ripening of raw materials and fermentation to aging and bottling—temperature control remains paramount. Failure to maintain the specific temperatures required to guarantee quality will result in substandard wine, regardless of how premium the raw materials or brewing equipment are; even the best inputs will yield disappointing results if the thermal environment is not properly managed.Brewing experts list the following reasons:1.High temperatures promote oxidation, microbial spoilage, and instability.2.Fermenting and storing under heated conditions causes the desired aromas and spices other than alcohol to evaporate completely.3.When temperatures exceed 38°C, yeast becomes inactivated and fermentation may be hindered by residual sugar.It is essential to strictly control the temperature required at every stage of the brewing process; a single oversight compromising wine quality would deprive the world of fine wine.Simultaneously, monitoring and managing oxygen and carbon dioxide levels during brewing can further enhance wine quality.1.Traditional Detection MethodsCurrently, China widely adopts relatively traditional methods for measuring fermented grain temperature, involving manual insertion of glass thermometers into grain blocks for measurement and recording. This operational model suffers from the following shortcomings:1.Glass thermometers are fragile, and leaked mercury contaminates starter culture blocks. Additionally, the thermometers are short and cannot fully reflect temperatures at different locations.2.The workload is heavy, recording is untimely, and efficiency is low. For larger fermentation chambers with dozens or even hundreds of monitoring points per room and multiple chambers, assigning one worker to complete a full temperature measurement cycle takes a long time. The daily workload exhausts data collectors, becoming unsustainable over time. Meanwhile, recorded data lacks synchronization and comparability, collected data has little practical significance, and work efficiency is very low. Increasing the number of workers will inevitably raise production costs.3.Data lacks continuity, making it difficult to observe temperature trends during fermentation. This hinders systematic analysis and judgment of the fermentation process and impedes improvements in fermentation techniques.4.Errors or omissions in manual data entry occur frequently, making it difficult to guarantee the accuracy and completeness of data records.Outdated data monitoring and recording methods are incompatible with the modern, informatized, and automated development concepts and directions of enterprises, inevitably causing adverse impacts on corporate development. Keeping pace with the times, improving temperature monitoring methods in the starter-making process, and adopting modern, automated, and intelligent monitoring and management systems are top priorities that every enterprise must emphasize and develop urgently. This yields twice the result with half the effort and holds immense significance!The intelligent starter culture temperature measurement system ideally resolves all the aforementioned issues and is the temperature monitoring solution actively adopted by major wineries.Solution for Automated Brewing Environment DetectionOur company has developed a smart environmental detection system tailored to every technological process of liquor production. This system is capable of monitoring temperature and carbon dioxide levels in real-time throughout the entire brewing cycle, with all data uploaded instantly to a cloud platform.System ArchitectureThe system consists of four core components: Front-end Sensors, Wireless Transmission Modules, Alarm Terminals, and a Cloud Platform.Sensors & ConnectivityThe sensors include insertion temperature probes, temperature/humidity sensors, and CO2 sensors. Notably, the insertion probes and T/H sensors utilize LoRa/LoRaWAN wireless transmission. Operating in a low-power mode and powered by batteries, these s

How to Select Inclinometers for Rack MonitoringIn modern warehousing and logistics systems, heavy-duty high-rise racks serve as the core carriers for goods storage. Factors such as prolonged heavy loads, collisions from forklift operations, foundation settlement, and environmental temperature and humidity fluctuations can all lead to subtle tilting and deformation of rack uprights. These latent failures are difficult to detect with the naked eye, and traditional manual inspections suffer from low efficiency and high rates of missed detection, easily creating hidden dangers of collapse. Therefore, deploying high-precision inclinometers for 24-hour real-time monitoring has become a standard requirement for safe and compliant operations in warehousing enterprises. Faced with a vast array of monitoring equipment on the market, most companies struggle with selection. To address this, Shenzhen Hengyi Technology offers two targeted solutions: a battery-powered model and a constant power supply model, specifically designed for rack monitoring. These products adapt to different warehouse scenarios, providing the industry with precise and efficient selection options.The primary criteria for selecting a rack monitoring inclinometer are measurement accuracy​ and environmental adaptability, which form the foundation for ensuring reliable monitoring data. Rack deformation often involves millimeter-level micro-changes that ordinary low-precision sensors cannot capture. Both models of Hengyi Technology’s HYS07 series inclinometers are equipped with imported high-precision triaxial sensors, uniformly achieving an ultra-high measurement accuracy of ±0.1° and a resolution of 0.0055°. This enables them to precisely identify subtle tilt changes in racks. Additionally, the devices support dual-range configuration (±10°, ±90°), allowing flexible adjustment according to the specific monitoring needs of high-bay or heavy-duty racks. Both triaxial inclinometers feature IP67 industrial-grade protection, making them resistant to complex working conditions such as warehouse dust, moisture, and temperature fluctuations, ensuring stable operation around the clock and eliminating monitoring errors at the hardware level.Scenario Adaptability and Power Supply Mode​ are key considerations in the selection process and represent the core differentiation between the two products.1. Battery-Powered ModelDesigned for renovation scenarios where wiring is difficult—such as existing warehouses, temporary storage facilities, and outdoor warehouses—the battery-powered inclinometer from Hengyi Technology is the ideal solution.Equipped with a built-in 19000mAh large-capacity battery, it requires no external power supply or cabling, completely eliminating the high costs associated with construction and line modification. The device features an external LoRa antenna and supports LoRa/LoRaWAN wireless transmission, offering strong anti-interference capabilities and long transmission distances. Installation is simple and convenient; it only needs to be securely fixed to the flat surface of the rack upright. With its wire-free and maintenance-free characteristics, it is perfectly suited for storage scenarios where wired power is inconvenient and rapid deployment is required.2. Constant Power Supply ModelFor scenarios requiring long-term stable monitoring and integration with automation systems—such as standardized smart warehouses and fully automated high-bay storage—Hengyi Technology's constant power supply inclinometer offers distinct advantages.The device supports DC 9~36V industrial wide-voltage power supply, making it compatible with mainstream factory power systems to ensure stable, uninterrupted operation. It is equipped with a standard RS485 interface using the MODBUS protocol, allowing for direct connection to PLC industrial control systems and seamless integration into the warehouse automation architecture. The transmission mode is compatible with both RS485 wired and wireless options, balancing stability with flexibility.A unique feature of this model is its discrete output (switching value) function, which can directly link to audible and visual alarms. This enables instant local alerts for tilt levels exceeding safety thresholds. When combined with remote cloud-based push notifications, it forms a dual-layer protection system, perfectly suited for the high-standard, high-demand safety monitoring requirements of intelligent warehousing.Intelligent Operation and Maintenance Capabilities​ are a significant differentiating factor in the modern inclinometer selection process. Both devices support IoT cloud monitoring; collected real-time inclination data can be uploaded to cloud platforms via gateways, 4G/5G, or Ethernet, enabling 24-hour unattended surveillance. The platform visually displays rack posture data in real-time, automatically generates monitoring reports, and records deformation trends, effectively replacing traditional manual inspection

Why do ordinary door sensors fail en masse when temperatures drop?​— Unfazed by extreme cold and snow! Low-temperature 4G door sensors designed for outdoor power distribution cabinets safeguard electrical security.​In electrical security and maintenance scenarios, outdoor distribution boxes and cabinets are exposed year-round to harsh open-air environments. They must withstand severe frost, sudden temperature swings, unmanned operation, and risks such as unauthorized access. In northern regions during winter—or in remote, wind-swept locations—ordinary security door sensors often malfunction, lose signal, or stop detecting altogether. This makes it impossible to monitor the status of cabinet doors in real time, creating opportunities for equipment theft, cable damage, and potential power failures, which severely disrupt maintenance operations.To meet the demanding operating conditions of outdoor electrical equipment, we have launched a specialized low-temperature 4G door sensor for outdoor distribution cabinets. With industrial-grade cold resistance, stable data transmission, and intelligent monitoring functions, it provides comprehensive protection for outdoor power distribution assets—even in the harshest climates.Why Do Door Sensors Fail En Masse in Cold Weather?​— And How to Solve ItSo, what exactly causes door sensors to fail in groups? Based on real-world usage experience, the root causes generally boil down to two main factors.Reason 1: The Battery ⚡ — Cold weather drains its strength and reduces performanceLow temperatures leave the battery “too weak to work,” significantly impairing its performance.Chemical reactions slow down:​ In cold environments, the electrolyte thickens or even partially solidifies, slowing ion movement and sharply reducing chemical activity.Internal resistance increases:​ Resistance inside the battery rises, resulting in lower output voltage and reduced usable capacity.Overall capacity drops:​ Electrode materials contract in low temperatures, reducing the amount of storable energy and lowering total charge.Reason 2: The Magnet 🧲 — Ordinary magnets temporarily lose strength in freezing conditionsStandard magnets become “listless” in low temperatures, weakening their magnetic force.Loss of magnetic strength:​ Cold suppresses certain magnetic domains, causing a temporary drop in magnetism. This affects coordination with the reed switch and may lead to switching failure.Material limitations:​ Most door sensors use ferrite magnets, which are highly sensitive to low temperatures. For example, at –5°C, magnetic strength may decrease by approximately 30%.Is There a Product Designed Specifically for These Challenges?​Yes—there is.To address these pain points, Shenzhen Hengyi Technology​ has launched a Low-Temperature Door Sensor​ built for extreme environments.Power Supply:​ Uses a constant power source instead of batteries, completely eliminating concerns about cold-induced battery failure.Probe Magnet:​ Equipped with a neodymium‑iron‑boron (NdFeB) rare-earth magnet, unlike conventional ferrite magnets, capable of operating in temperatures ranging from –40°C to +110°C.Host Electronics:​ Industrial‑grade electronic components rated for –40°C to +85°C, ideal for the wide temperature fluctuations common in northern China.Key FeaturesHardcore Cold-Resistance Configuration for All Outdoor Low-Temperature Conditions​Unlike consumer-grade or standard industrial sensors, this model is purpose-built for extreme cold. It integrates industrial-grade cold-resistant components, high-precision reed switches, and high-strength magnetic assemblies to overcome the industry-wide challenge of cold-weather device failure.Operating temperature range: –40°C to +80°C​Performs reliably in sub-zero northern winters, extreme day-night temperature swings, frost, snow, and high-wind environments.No magnetic failure, circuit faults, freezing, or disconnections caused by low temperatures.Highly Sensitive Detection & Ultra-Low Power Consumption​Normally-closed switch design:​ The circuit closes instantly when the magnet approaches.Detection distance:​ ≥ 70 mm under interference-free conditions, ensuring fast, accurate response without lag or false alarms.Power consumption:​ Strictly controlled below 3 W, supporting 24/7 continuous operation with minimal maintenance—perfect for long-term unmanned outdoor power distribution applications.2. 4G Wireless Smart Transmission — Real-Time, Precise Cabinet Status Monitoring​Outdoor power distribution cabinets often face challenges such as difficult wiring, scattered installation points, and complex maintenance workflows. To address these pain points, this low-temperature door sensor integrates a 4G wireless communication module, freeing installation from the constraints of wired cabling and enabling deployment in various outdoor environments—whether in remote fields, urban streets, or industrial zones.Data is transmitted via the reliable MQTT protocol, ensuring that cabinet
