The Soil Moisture Sensor or the hygrometer is usually used to detect the humidity or wetness of the soil. This sensor is perfect for building an automatic watering system or to monitor the soil moisture of your plants. The sensor kit is set up by two pieces: the electronic board, and the probe with two pads, that detects the water content. The sensor has a built-in potentiometer for sensitivity adjustment of the digital output (D0), a power LED and a digital output LED to use for viewing the output state of the sensor board.
