## Description

The SparkFun Qwiic Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. The more water in the soil, the better the conductivity between the pads will be, resulting in lower resistance and a higher SIG output. This version of the Soil Moisture Sensor features a Qwiic connector, making it even easier to use.

To get the SparkFun Soil Moisture Sensor functioning, simply connect the VCC and GND pins to your Arduino-based device (or a compatible development board). You will receive a SIG out, which will depend on the amount of water in the soil. One commonly known issue with soil moisture sensors is their short lifespan when exposed to a moist environment. To combat this, we’ve had the PCB coated in gold finishing (ENIG, or Electroless Nickel Immersion Gold).
