Water sensor

A water sensor is a special tool that helps us know when water is present in places where it shouldn't be. It works by using small metal probes that can sense if water is touching them. When the probes detect water, they send a signal to an alarm or notification system, which can alert us to the presence of water. This is helpful because water can cause damage to things like floors, walls, and electronics. By using a water sensor, we can quickly find and fix any water problems, which helps keep everything safe and dry!
