Milesight IOT - Leak Detection Sensor (Rope Type)

The EM300-ZLD is a compact area leakage detection sensor designed to detect the presence of water (or other liquids) over a large surface area and transmit alarms using LoRaWAN® technology.

Thanks to this low-power technology, the EM300-ZLD can operate for up to 5 years with a 4000mAh battery.

Combined with Milesight's LoRaWAN® gateway and Milesight IoT Cloud solution, users can remotely manage all sensor data and visually receive alerts via a mobile app.

The EM300-ZLD also integrates temperature and humidity sensors, which are valuable for applications such as pipe leak monitoring, basement floods, pump failures, etc.

Features:

• Detect liquid presence through a long cable and based on the conductivity principle
• Integration of temperature and humidity sensors for environmental monitoring
• Ultra-long-distance transmission with a range of up to 10km
• IP67 waterproof and UV-resistant housing for use in harsh environments
• Replaceable built-in 4000mAh battery that operates for 5 years without replacement
• Equipped with NFC technology for easy configuration
• Compatible with standard LoRaWAN® gateways and network servers
• Quick and easy management with the Milesight IoT Cloud solution
