Control with reliable real-time data

EM300-TH is a compact environmental monitoring sensor that measures temperature and humidity and transmits data using LoRaWAN technology. Thanks to this low-energy technology, the EM300-TH can operate for up to 5 years on a 4000mAh battery. By combining Milesight's LoRaWAN gateway and Milesight's IoT Cloud solution, users can manage all sensor data remotely and visually.

EM300-TH is widely used for indoor and outdoor applications such as offices, hospitals, factories, greenhouses, etc.
