Milesight IoT Membrane Leakage Detection Sensor, EM300-MLD-868M (EM300-MLD-868M)

Detects liquid presence instantly upon contact with its conductive membrane, triggering an immediate LoRaWAN uplink alarm. This sensor is built for reliable leak detection in demanding environments.

Overview

The EM300-MLD-868M is a LoRaWAN-based membrane leakage detection sensor operating on the EU868 frequency band (863-870 MHz). It uses a conductive membrane principle to detect leaks, making it suitable for monitoring water or other conductive liquids. The device is powered by two ER14505 Li-SOCl2 batteries with a combined capacity of 5400 mAh, delivering an estimated battery life of up to 5 years. Configuration is done via NFC using the Milesight ToolBox App, and the data transmission interval is configurable from 10 minutes to 24 hours.
