EM300-SLD LoRaWAN Spot Leak Detection Sensor
Please fill in your details below, we will get back to you as soon as possible
EM300-SLD is a compact spot leakage detection sensor for detecting the presence of water (or other liquids) and transmitting alarms using LoRaWAN® technology. With this low power consumption technology, EM300-SLD can work up to 5 years with a 4000 mAh battery. Combining with the 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 great use for applications such as pipe leakage monitoring, basement flooding, pump failure, etc.
