LoRaWAN® EM300-ZLD Wide Area Leak Sensor and T°C/Humidity – Milesight
 General Description
 Milesight 's EM300-ZLD is a cable-based leak detector designed to monitor large sensitive areas for the presence of water or conductive liquids. Using a 3-meter (customizable) wired probe, it combines leak detection, temperature and humidity measurement, and LoRaWAN® transmission. It is waterproof and UV-resistant (IP67), making it suitable for outdoor or harsh environments. It also offers local data storage, automatic retransmission, and compatibility with the Milesight D2D protocol.
 Targeted Applications
-  Leak monitoring in large areas (technical rooms, technical floors, pipes)
 
-  Flood prevention in cellars, parking lots or basements
 
-  Industrial or logistics systems
 
-  Climate monitoring in hostile environments
 
 Highlights
-  3m cable detection (customizable)
 
-  Measurement of ambient temperature and humidity
 
-  IP67 waterproof UV resistant housing
 
 - Up to 10 km LoRaWAN® range in open field
 
-  Up to 10 years of battery life
 
-  D2D functions, local storage (3000 data) and retransmission
 
-  Easy setup via NFC
