Milesight EM300-SLD: Smart flood prevention with LoRaWAN technology.

Protecting infrastructure from water damage is a top priority. The Milesight EM300-SLD is a smart sensor designed to promptly detect liquid leaks, preventing flooding in basements, offices, and industrial sites before they turn into costly emergencies.
3-in-1 Security and Monitoring
In addition to the leak detection probe (based on the conduction principle), the EM300-SLD integrates temperature and humidity sensors. This combination enables complete environmental monitoring, ideal for checking the integrity of pipes, server rooms and warehouses.
Extreme Resistance and Long Life
Designed to operate in the harshest environments, the sensor features an IP67 certification (waterproof and UV-resistant) and an operating range from -30°C to +70°C. Thanks to the 4000 mAh battery and LoRaWAN® technology, the device ensures operation up to 5 years with no maintenance required.
