The most basic diy devices are battery-operated discs or small boxes that simply sit on the floor where leaks might occur, such as directly under a refrigerator, sink, toilet, or washing machine. They typically have two or more metal sensor terminals … smart water sensors cost anywhere from $50 to over $500. The more affordable models are just leak detectors that typically lack a wi-fi radio and communicate via bluetooth or work as part of a home automation system.

Prevent water disasters with advanced leak sensors that alert you instantly via app, email, and loud alarms - plus automatic water shut-off for peace of mind.
