LoRaWAN® EM300-SLD Leak Detection and T°C/Humidity Sensor – Milesight
General Description
Milesight 's EM300-SLD sensor is a compact and robust point leak detection sensor for water or conductive liquids, designed to operate in harsh environments thanks to its UV-resistant IP67 housing. Also equipped with temperature and humidity sensors, it is an ideal solution for environmental monitoring of sensitive areas such as basements, pipes, technical rooms or pumping systems. It features long-range transmission via LoRaWAN®, local data storage (3000 records), a retransmission function and the Milesight D2D protocol with very low latency.
