Simple Water Level Detector

This is so useful circuit diagram because this circuit helps us to detect water.When the water come and touch the sensors it will make a sound.Here I have used common transistor bc109. Actually you can modify this circuit.. By using a relay you can switch on or off your water motor I will tell you them in my next post.


# Use 6V to power this circuit
# The distance between the circuit and the sensors should be short.
# Build this circuit on a pcb to get good result.
