Warehouse Environmental Monitoring System Solution

The warehouse/storage‑room environmental monitoring system is designed to collect data within a localized area, primarily focusing on air quality, ambient temperature, and humidity. It comprises a gateway equipped with a 10.1‑inch display, two LoRa/LoRaWAN temperature and humidity sensors, one CO₂ sensor, one PM10/PM2.5 sensor, and two LoRa/LoRaWAN water‑infiltration sensors. The system monitors and records various environmental parameters in the storage facility. Environmental data are transmitted wirelessly via LoRa/LoRaWAN, as well as through RS485 and RJ45 interfaces, to the gateway. Upon receiving the data, the gateway displays it locally and stores it in its internal memory.

Paperless Temperature and Humidity Recording System

The paperless temperature and humidity recording system consists of a gateway with a 10.1-inch display and ten RS485‑compatible temperature and humidity sensors. It is used to monitor and log ambient temperature and humidity data. Temperature and humidity readings are transmitted via RS485 to the gateway, which then displays the data locally and stores it in its internal memory.

Wireless PT100/PT1000 Paperless Temperature Recording System

The wireless temperature and humidity paperless recording system consists of a gateway equipped with a 10.1-inch display and ten two-channel transmitters supporting LoRa, LoRaWAN, RS485, PT100, or P1000 interfaces. It is used to measure and record the surface temperatures of various objects. Temperature and humidity data are transmitted to the gateway via RS485 or wirelessly over LoRa/LoRaWAN; upon receiving this data, the gateway displays it locally and stores it in its internal memory.

Wireless Plug-in Temperature and Humidity Paperless Recording System

The wireless plug-in temperature and humidity paperless recording system consists of a gateway with a 10.1-inch display and ten plug-in LoRa/LoRaWAN temperature sensors. It is used to measure and record the internal temperature of various objects under test. Temperature data is transmitted wirelessly via LoRa/LoRaWAN to the gateway, which, upon receiving the temperature and humidity readings, displays them locally and stores them in its onboard memory.

What effects do millimeter-wave radar sensors have on the human body?

Do millimeter-wave radar sensors have any effects on the human body? In recent years, millimeter-wave radar sensors have been widely adopted, particularly in fields such as autonomous driving, security monitoring, and medical diagnostics. So, do these sensors actually pose any health risks to humans? First, it’s important to understand how millimeter-wave radar sensors work. These sensors emit electromagnetic waves in the millimeter-wave band; when these waves encounter an object, they are reflected back. By measuring the time and intensity of the reflected signals, the sensor can determine the object’s position, velocity, and shape. Because millimeter-wave electromagnetic waves have short wavelengths, high frequencies, and substantial energy, some people worry about potential impacts on human health. Hengyi Technology’s 60 GHz millimeter-wave radar sensors offer an exceptionally wide detection range. As a result, whether in wet or slippery areas like kitchens and bathrooms, or in open spaces such as bedrooms and living rooms, they can accurately detect falls in real time.

This article explains the differences and similarities between PT100 and PT1000 sensors.

One article explains the differences and similarities between PT100 and PT1000 sensors. The most obvious distinction lies in their resistance–temperature relationships. A PT100 sensor has a resistance of 100 Ω at 0°C, whereas a PT1000 sensor exhibits a resistance of 1000 Ω at the same temperature. This difference means that the PT1000 sensor is more sensitive to temperature changes, making it more commonly used in applications requiring higher‑precision temperature measurements. Both types operate on the principle that platinum’s electrical resistance varies with temperature. Platinum is a material renowned for its high‑accuracy temperature measurement capabilities; its resistance–temperature relationship is highly linear and stable, enabling PT100 and PT1000 sensors to deliver precise temperature readings across a wide temperature range.

Smart Power Storage Cabinet Fire Protection System

Our company has developed an intelligent fire‑suppression system for power‑storage cabinets. Building on conventional fire‑protection systems, we have designed several specialized front‑end fire‑detection devices tailored to the unique characteristics of these cabinets and integrated IoT technology into their fire‑suppression architecture. In terms of front‑end sensing, we have developed a lithium‑battery leakage sensor, an infrared matrix sensor, an organic volatile compound (VOC) detector, and a linear heat‑sensing cable. When any of these sensors detect signs of battery ignition or abnormal temperature spikes, they transmit the data via I/O or RS‑485 to the cabinet’s alarm control unit. The control unit employs advanced algorithms to analyze the incoming signals; upon identifying symptoms of a lithium‑battery fire, it activates the perfluorohexanone extinguishing agent through its I/O interface while simultaneously reporting the incident over Ethernet and via 4G/5G networks.
