Detailed Technical Explanation of LoRa Wireless Temperature and Humidity Monitoring Sensors for Campus Applications
The wireless temperature and humidity monitoring sensors deployed in campus environments utilize advanced wireless sensing technology based on the latest LoRaWAN communication protocol, offering several key advantages. First, they feature ultra-low power consumption—equipped with high-capacity built-in batteries that enable continuous operation for 2 to 3 years. The communication range reaches up to 5 kilometers without obstructions, and remains stable at over 50 meters within fully loaded data centers, capable of reliably penetrating 3 to 4 layers of concrete structures. Frequency hopping technology is employed to avoid congestion in the 2.4 GHz band.
The intelligent sensor has been upgraded with LoRa communication, eliminating the need for cabling. It simultaneously monitors temperatures from -20°C to 70°C with an accuracy of ≤±0.5°C, and humidity levels from 5% to 95% RH with an accuracy of ≤±5%. The data upload interval is configurable, ranging from 10 to 3600 seconds. This temperature and humidity sensor is also suitable for environmental monitoring in server rooms, warehouses, greenhouses, and similar applications.
For standard monitoring areas, it is recommended to install one sensor per 30–50 square meters. Place sensors away from air conditioning vents and direct sunlight, at a height of 1.2 to 2 meters (an optimal height for human perception). The sensor supports both magnetic mounting and wall installation.
