Overview
EM300-SLD overview
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.
