[0002] A water sensor is a device that detects the presence or location of liquid (usually water). It is used to monitor and control flood risks and protect equipment and property. When water is detected, the sensor sends a signal to the alarm system or control system, triggering an alarm or shutting down the device. It is commonly used in homes, factories, computer rooms, and other places.

[0003] First, the user selects an installation location based on the direction of water flow and accumulation points. A hole is then drilled at the selected location and the water sensor is secured to the installation location using screws and other fixings.

Furthermore, in environments prone to false water traces (such as steam or spray), water sensors are prone to false alarms. Therefore, a water sensor with adjustable contact height is needed to address this issue. Utility Model Content
