SwitchBot W4402000 - Water Leak Detector

The SwitchBot W4402000 Water Leak Detector is a smart sensor for monitoring residential spaces against water damage. It detects dripping water, full immersion, and rising or falling water levels in containers. The device runs on battery power, giving it an operational life of up to two years. An integrated audible alarm produces a local warning of up to 100 dB when moisture is detected. Combined with its long battery life, this provides consistent, low-maintenance monitoring. The sensor is intended for use near plumbing, tanks, and household appliances.

The housing has an IP67 rating, protecting the internal electronics from dust and temporary immersion in water. This build quality means the unit continues to function reliably even if the monitored area floods. Connectivity uses Wi-Fi and Bluetooth to integrate with the home network. The detector works with Amazon Alexa and Google Assistant for voice control. Users can monitor the system remotely through a smartphone or tablet app. The straightforward installation makes it easy to place in tight spaces under sinks or near washing machines.
