Rain Detector / Rain Sensor

Rain-sensorSome models come with a basic analogue to digital converter that's adjustable.  It requires a 3 volt and ground connection, and has a signal line which triggers when wet.

I wired the signal connector directly to a GPIO.  It may also run at 5volts but didn't want to risk the pi.
