Advanced Protection Against Costly Water Damage
Prevent catastrophic damage to property and assets with the Milesight Zone Leakage Detection Sensor. This industrial-grade sensor provides immediate, reliable alerts for the presence of water or other conductive liquids across a large area. Ideal for basements, data centers, warehouses, and any location susceptible to leaks, the EM300-ZLD uses LoRaWAN technology to transmit alarms over vast distances. Beyond simple leak detection, it integrates high-accuracy temperature and humidity sensors to offer a complete environmental monitoring solution, helping you safeguard sensitive equipment and prevent conditions that could lead to mold or corrosion.
Engineered for Reliability and Longevity
Designed for 'fit and forget' deployment, the sensor is powered by a high-capacity 4000 mAh Li-SOCL2 battery, enabling it to operate for up to 5 years without replacement. Its rugged, IP67-rated waterproof and UV-resistant enclosure ensures dependable performance even in the harshest indoor or outdoor environments. Configuration is made simple through NFC technology, allowing for quick setup and management directly from your mobile device. As part of the Milesight IoT ecosystem, you can visually manage sensor data, receive instant alerts via a mobile app, and gain valuable insights through the Milesight IoT Cloud.
