Product Description

The Milesight EM300-ZLD is a compact and effective zone leakage detection sensor, expertly designed for detecting the presence of water or other liquids over large areas. This sensor is a vital tool for applications such as pipe leakage monitoring, basement flooding, and pump failure. Utilizing LoRaWAN® technology, the EM300-ZLD stands out with its low power consumption, functioning up to 5 years with a single 4000mAh battery, making it a durable and cost-effective solution.

Key to the EM300-ZLD's functionality is its integrated temperature and humidity sensors, allowing for comprehensive environmental monitoring. This sensor is capable of ultra-wide-distance transmission up to a line of sight of 10km, which is particularly beneficial for large-scale applications. Encased in an IP67 UV-resistant and waterproof enclosure, it is well-suited for harsh environmental conditions, ensuring reliability and longevity.

Furthermore, the EM300-ZLD can store up to 3,000 historical records locally and supports retransmission to avoid data loss. It also supports the Milesight D2D protocol, enabling ultra-low latency and direct control without the need for gateways. For ease of use, it is equipped with NFC for straightforward configuration. When used in conjunction with the Milesight LoRaWAN® gateway and IoT Cloud solution, users can remotely manage sensor data and receive timely alarm notifications via a mobile app.
