Introduction: Water Detector
This Circuit is simple and useful to detect floods. It can operate another circuit to stop electricity if there is a flood.
#The sensor is made from 2 pieces of metal connected to the PCB (sensor). If the 2 leads are in water the circuit will trigger.
It is an easy and cheap circuit powered by 9V.
