Sometimes we forget about the filling of a water tank or think that it is full. So that we face a problem when it gets empty. So this circuit will help you to indicate the level of water in a water tank.
What is a Water Level Indicator?
A water level indicator is a sensor that tells us about the status of water in a water tank that is Full, Middle, or Empty.
This circuit is very useful as it tells you that your tank is going to turn off your water pump. This also helps us to save water.
