LoRaWAN environmental monitoring sensor

Minimize Losses from Water Leaks

The EM300-MLD Membrane Leakage Detection Sensor, our newest addition to the water leak detection product line, features a 40 cm x 40 cm detection membrane, ensuring dependable water leak monitoring for both residential and commercial applications.

Secure Every Inch with Membrane Leakage Detection

Unlike rope or spot leak sensors, the EM300-MLD Membrane Leakage Detection Sensor offers a 40cm x 40cm membrane, enabling it to cover broader areas and effectively detect water leakage.

Meeting Needs with Custom-Fit Membrane

The membrane of the EM300-MLD can be vertically trimmed to fit specific requirements. Also, it supports large-size customization (Contact Milesight).

Versatile Protection for Every Space

Designed to meet various needs, the EM300-MLD is suitable for both residential and commercial environments. Whether it's placed under appliances like washing machines and refrigerators or used to monitor roofs and ceilings for potential leaks, this sensor provides comprehensive coverage and ensures timely notifications to prevent costly damages.

Robust Data Storage and Retransmission

The EM300-MLD stores up to 1,000 sets of historical data records locally. With data retrieval and retransmission support, it ensures data integrity even during occasional network downtime.

Comprehensive Water Leak Solution

Milesight offers both zone-based and spot-based leak detection options to suit various needs. Whether you require coverage for larger areas or pinpoint accuracy, we have the right products for you.

Ultra-Low Power Consumption

The EM300-MLD provides an operational lifespan of up to 10 years using a single battery, with the option to further extend it using two batteries.
