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
