Note: Unfortunately, the design of this sensor isn't intended for long term exposure to outdoor environments. It is primarily intended for the classroom setting. This is due to the limitations in waterproofing the sensor and its connections.

Connecting your gator:soil to the gator:bit (v2) is simple. Connect GND to GND, SIG to an analog pin (P0-P2)1, and PWR to either 3.3V OUT or to a digital pin that is not in use (P0-P2, P8, P16, or P5). This can easily be done with alligator cables or these special banana cables.
