The WDS series products are wireless data sensors that use LoRA communication for data cleaning and transmission to achieve centralized monitoring of temperature and humidity data. This design greatly reduces the difficulty of construction, improves construction efficiency, and reduces maintenance costs. The product is equipped with an LCD display, dual control of upper and lower limits of temperature and humidity, free setting of limit values, and temperature and humidity calibration by giving a password.
