Milesight EM300-SLD Standard Leak Detection LoRa Sensor

Milesight EM300-SLD Standard Leak Detection LoRa Sensor

EM300-SLD is a compact spot leakage detection sensor for   detecting presence of water (or other liquids) and transmitting  alarm using LoRaWAN® technology. With this low power  consumption technology, EM300-SLD can work up to 5 years  with 4000 mAh battery. Combining with Milesight LoRaWAN®  gateway and Milesight IoT Cloud solution, users can manage all  sensor data remotely and visually and receive alarms via mobile  APP. 

EM300-SLD also integrates temperature and humidity sensors,   which has a great use for applications such as pipe leakage  monitoring, basement flooding, pump failure, etc.
