The Milesight WS203 Motion + Temp is a LoRaWAN environmental sensor that combines PIR motion detection with high-accuracy temperature and humidity sensing. It detects human presence while periodically reporting ambient conditions, making it ideal for smart offices, hospitals, and building automation where occupancy-driven climate control saves energy.
