Milesight EM300-MLD | LoRaWAN Membrane Leakage Detection Sensor

The Milesight EM300-MLD represents the next generation of Water Leakage Detection, moving beyond single-point pins to a comprehensive 400x400mm sensing area. This LoRaWAN-enabled device utilizes a flexible printed membrane that can be placed flat under appliances or customized to fit specific architectural contours. Unlike traditional cable sensors, the membrane is reusable, eco-friendly, and offers superior sensitivity for detecting water, weak acids, or weak bases. With an integrated 4000mAh battery providing up to 10 years of service life and a rugged IP67 enclosure, the EM300-MLD is the ideal solution for protecting high-value assets in server rooms, laboratories, and smart buildings.

Advanced Surface Leak Intelligence

Customizable Detection Area The high-quality membrane can be cut to suit specific detection zones without compromising the black-line circuit, allowing for bespoke installations. Data Reliability Features Supports local storage of up to 1,000 entries and features data retransmission to ensure critical leak alarms are never lost during network outages.

Professional Protection Scenarios

• Server Rooms: Monitor large floor areas under raised tiles to detect cooling system failures. • Smart Buildings: Hide the thin membrane under washing machines or refrigerators for invisible leak protection. • Equipment Cabinets: Protect electrical workshops and sensitive machinery from localized pipe bursts.
