The WS-CWS-RDJH-100 temperature and humidity sensor is composed of a high-precision sensor and a wireless communication unit. It uses a low-power temperature and humidity acquisition chip and a wireless LoRa module to measure the temperature and humidity of the surrounding environment of the equipment. It is mainly used to monitor temperature and humidity changes in substations, power distribution rooms, UPS computer rooms and other scenes. When limits are exceeded, it can be linked to other equipment to achieve automatic control of temperature and humidity to ensure the safe operation of the equipment.
Main functions and characteristics
1）Using a dedicated low-power temperature and humidity acquisition chip, it has a wide measurement range and high accuracy;
2）Low cost of use and maintenance;
3）Wireless upload, data visualization;
4）Wide range of applications.
