Two of the sensor has four pins\nare ground and +5V; the other two are clock and data pins that make up the\n2-wire serial interface. The board is 5V tolerant and designed to operate\ndirectly off the supply voltage. The sensor can be placed in soil to measure\nmoisture and temperature, which makes it ideal for using it in a garden or\ngreenhouse. The humidity sensor is also especially useful in building remote\nweather stations.
