Core Configuration of China’s Private LoRaWAN Network

The core configuration of China’s LoRaWAN private network is designed for low‑rate, long‑battery‑life IoT applications such as environmental monitoring and asset tracking. Its key design features include: - Unlicensed spectrum: No license required, making it ideal for enterprise‑built networks. - Spread‑spectrum anti‑interference: With a 125 kHz bandwidth and CSS modulation, it offers strong penetration and a coverage range of 10–15 kilometers. - Flexible networking: Supports star and mesh topologies, with gateways capable of demodulating up to eight concurrent channels (e.g., using the SX1301 chip).

New Arrival – Multi-Point Infrared Thermometer

With the intelligent upgrading of power systems, the need for safety monitoring of distribution cabinets is becoming increasingly urgent. Traditional manual inspections rely on specialized personnel to open cabinets for testing, which is inefficient, costly, and often fails to promptly detect localized overheating risks caused by poor contact or overload, posing a significant fire hazard. In response, our company’s R&D team has focused on infrared sensing and IoT technologies to develop the HYT80 multi-point infrared thermometer. Featuring an 80×62 high‑precision infrared pixel array, this device delivers wide‑range temperature measurement from –20°C to 400°C with an accuracy of ±0.25°C. Coupled with multiple field‑of‑view options (45°/90°/105°) and MODBUS protocol compatibility, it enables non‑contact, real‑time monitoring of temperature changes inside distribution cabinets. By transmitting data over networks and leveraging big‑data analytics, it can proactively identify potential risks, providing an efficient, low‑cost, intelligent solution for power‑system safety.

Does multi-point temperature measurement require installing multiple devices? A single probe enables three-layer monitoring, providing full coverage for tobacco leaves, tea leaves, and grain stacks.

In traditional industries such as tobacco leaf aging, tea fermentation, and grain storage, the accuracy and efficiency of temperature monitoring directly impact product quality and production safety. Faced with challenges like bulky material piles, complex environments, and numerous monitoring blind spots, conventional multi-point deployment not only entails high costs but also struggles to meet real-time control requirements due to fragmented data and cumbersome operations. The wireless insertable temperature‑monitoring system breaks new ground through technological innovation; our company has adopted a “single probe, three‑layer temperature measurement” design that integrates multi‑point monitoring into a single solution, addressing the industry’s most pressing pain points.

Dust‑prone environments, sealed containers, and dam monitoring—no challenge too great! An analysis of the multi‑industry applications of wireless level‑measurement systems.

In industrial settings, numerous liquid tanks like the one shown above require real-time level monitoring. Millimeter-wave radar sensors offer a non-contact, zero‑contamination, fast, and convenient solution, making them ideal for monitoring closed vessels in industries such as chemical processing and food manufacturing, where they can easily measure the liquid height inside the tank. At the heart of this wireless level‑monitoring system lies 60 GHz millimeter‑wave radar technology. By combining non‑contact, high‑precision measurement (±1 mm) with multi‑mode wireless communication (LoRa/4G/WiFi), it seamlessly adapts to complex environments—such as dust‑filled industrial silos, river‑water level sensing amid aquatic vegetation, and sealed, high‑risk liquid storage containers—enabling all‑weather, low‑maintenance level monitoring. From boosting production efficiency to ensuring public safety, this innovative system is driving level monitoring toward an intelligent, highly efficient future.
