Simple Water Detection Sensor

This palm-sized cherry-red water sensor is simple

CHECK IT OUT

The sensor has a very lightly biased transistor that is connected to two long sets of interlocking traces. When a lil bit of water/condensation lands on the PCB and touches two of the traces, the transistor will turn on, setting the output pin high.
