    Description

    EM300-SLD Description

    Overview

    The EM300-SLD is a compact spot leakage detection sensor that detects conducting liquids via a small water probe and reports alarms over LoRaWAN. It also integrates temperature and humidity sensing for environmental monitoring at the leak location.

    Conductive Spot Detection

    A 1.5 m probe detects water or other conducting liquids when the level reaches about 5 mm, triggering timely LoRaWAN alerts before damage spreads across a facility.

    Environmental Monitoring

    Embedded temperature and humidity sensors add context around each leak event, helping distinguish condensation, flooding and HVAC failures.

    Long-Life & Reliable

    A built-in 4000 mAh replaceable battery supports up to 10 years of operation at a 10-minute interval with 24 triggers per day. Local storage and retransmission prevent data loss during outages.

    Field-Ready Design

    IP67 UV-resistant housing suits harsh indoor and sheltered outdoor sites. NFC configuration and Milesight D2D enable fast setup and ultra-low-latency local control.

    Industry Applications

    EM300-SLD Industrial Applications

    Data Centres & Server Rooms

    Spot probes under racks, CRAC units and pipe joints catch early leaks before equipment damage or downtime.

    Commercial Buildings

    Basements, mechanical rooms and elevator pits are monitored for conductive liquid presence with remote alerting.

    Smart Facilities

    Combined leak, temperature and humidity data integrates with BMS and Milesight IoT Cloud for automated response workflows.
