The gator:soil consists of two probes and three pads (PWR, GND, and SIG). The probes are used to measure the conductivity of the soil. SIG provides an analog voltage out that can be attached to an ADC pad on the gator:bit (v2). The value read on SIG is dependent on a few variable, including soil composition, contact on the probes, soil compaction, and other factors. In most cases, it will behoove you to calibrate your sensor reading for each soil sample and sensor.
