The EM300-ZLD is a compact zone leakage detection sensor for detecting the presence of water (or other liquids) over large areas and for transmitting alarms using LoRaWAN® technology. With this low-power consumption technology, EM300-ZLD can work up to 5 years with a 4000 mAh battery.
In combination with the Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all the sensor data remotely and visually as well as receive alarms via a mobile app. EM300-ZLD also integrates temperature and humidity sensors, which is very useful for applications such as pipe leakage monitoring, basement flooding, pump failure, etc.
