EM300-ZLD-868M: LoRaWAN Leak Detection Sensor

Rope-type for large area detection covered by 3m cable

### High-Sensitivity Leak Detection

The M300-ZLD is suitable for detecting the presence of water or other liquids and remotely alerting users to potential water leaks. It supports the detection of conductive liquid leaks when the liquid level reaches 5mm.

### Advanced Alarm Settings

With custom alarm reporting intervals and times, users can flexibly apply them in various scenarios.

### 3 Sensors in 1

The EM300-ZLD features temperature and humidity sensors for comprehensive monitoring in a single device.

### LoRaWAN Based

Penetrating signals: data transmission range up to 2 km in urban areas and 15 km in rural areas
High compatibility: compatible with standard LoRaWAN® gateways and network servers

### Milesight D2D Communication

The Milesight D2D (Device to Device) communication protocol with LoRa® enables communication between different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.

### Storage Capacity with 2,800 Sets of Historical Data Records

Data can be stored on the device and cannot be manually deleted, further ensuring the traceability of reported information.

### Retransmission Support for Reliable Communication

With data retransmission support, the device ensures that the web server receives all data even if the network is occasionally interrupted.

### NFC Configuration

Power on/off and configure the device via NFC technology from a mobile phone or PC
