Has an electronics engineer, you are required to come up with a circuit that controls the
water levels in a tank so that it saves water as well as powers when a tank is filled up by
cutting the power supply to the water pump. Write a project proposal that will explain the
working of the circuit?

 

Before coming to a circuit, can you visualise what has to happen?
Let me give you a start.

* Tank becomes full - stop pump.

 

Welcome to AAC!
Consider how you will detect if the tank is full, or is nearly empty and needs filling.
Research the power requirements of the pump.
Show us your work so far on this project.
