WS303 Mini Leak Detection Sensor
Smart Water Leak Detection Solution
Introducing 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.
Immediate Warning Against Water Damage
WS303 will sound an alarm and send a remote alert when water leakage occurs.
Sensitivity That Exceeds Expectations
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 Communication
