Automatic water tank level controller motor driver circuit

Posted on Feb 6, 2014

Automatic water level controller circuit is a simple engineering project. It can automatically switch ON and OFF the domestic water pump set depending on the tank water level. You can implement this motor driver circuit at your home or college using less costly components. The approximated cost of the project is about $5 only. The main advantage o

f this water level controller circuit is that it automatically controls the water pump without any user interaction. The heart of this pump controller circuit is a NE 555 IC; Here we have manipulated the flip flop inside the 555 timer IC. Our project consists of two water level sensors, one fixed at the top and other at the bottom. Working of this circuit is almost similar to a bi stable mutlivibrator. Simulation of this circuit is also given below. Definitely this will help you to do your academic project. In this project 3 wires are dipped in water tank. Let us define two water levels- Bottom (Low) level and Top (Up) level. One of the wire or probe is from Vcc. When water level goes down, the 2nd pin gets disconnected(untouched) from water i. e. voltage at the trigger pin becomes less than Vcc. Then the output of 555 becomes high. For practical implementation, you must use a relay. Rating of relay is chosen according to the load (Motor). 32 Ampere relay is best suited for domestic applications.
