Tokatuker’s wired water leak detector is a component, not a finished product. That’s its core strength. It’s designed to be integrated into a larger system, giving you direct control over the response to a leak. The included 10A relay is the key. When the sensor probes detect moisture, this relay can trigger a much more powerful action than a simple beep.

The relay output can handle up to 260V and 10A. In practice, this means you can wire it to a loud siren for a whole-house alarm or, more critically, to an automatic water shut-off valve. The sensor will immediately cut power to the valve, stopping the flow of water at the source. A sensitivity adjustment dial helps you fine-tune it to avoid false alarms from condensation or missing a real flood.

You’ll need a basic 12V DC power supply and some wiring know-how to get it running. This isn’t a plug-and-play alarm for under your sink. It’s a reliable, hardwired module for a serious leak prevention setup, ideal for securing a basement, laundry room, or water heater pan where a passive alarm isn’t enough.
