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

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