Crowtail - Water Sensor 2.0

The water sensor detects the presence of water using a series of exposed, grounded traces, including the sensor traces. These traces have a weak pull-up resistance of 1 M?. This resistance will raise the value of the sensor trace until a drop of water causes a short circuit between the sensor trace and the grounded trace. The amount of water-induced contact between the grounded and sensor traces can be detected using the digital I/O pins.
