Water Level Sensor

A water level sensor is an electronic component used to detect the presence or level of water in a container or tank. It works by detecting changes in electrical conductivity when water comes into contact with the sensor's conductive traces. The sensor can provide a signal to a microcontroller such as Arduino, which can then be used to activate a buzzer, LED, pump, or display according to the water level. It is commonly used in water tank monitoring, automatic water pumps, leakage detection, and smart irrigation projects.
