Milesight WS303 Mini Leak Detection Sensor

MIlesight LoRaWAN AS923/AU915 WS303 Mini Leak Detection IoT Sensor. Stop Leaks, Avoid Further Damage, the WS303, a mini water leak detection sensor that detects the presence of leaks and raises alarms locally and remotely. With low power consumption, it can operate for 5 years on a single battery. It's ideal for smart offices, buildings, houses, etc. WS303 will sound an alarm and send a remote alert when water leakage occurs. The WS303 sensor uses water conductivity to detect a minimum water level of 0.5 mm by forming a circuit with two little metal probes. (Other conductive liquids are also supported). Milesight D2D (Device to Device) communication protocol featuring LoRa® enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.

Perfect for smart buildings, smart city deployments or industrial use-cases.
