The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be, resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.\u003c\/p\u003e\n\u003cp\u003eTo get the SparkFun Soil Moisture Sensor functioning, all you will need is to connect the VCC and GND pins to your micro:bit or  Arduino-based device (or compatible development board).
