Timer based Water Level Controller Circuit

Last Updated on February 17, 2021 by Swagatam 56 Comments

CD 4060 based timer 9be8549fa77bb7793263 1 1

The explained circuit of a water level controller circuit is based on a adjustable timer circuit whose time delay is first adjusted to match the filling time of the tank, as the the tank fills, the timer delay also simultaneously lapses and its output switches OFF the water pump. Circuit Specifications Actually the circuit was […]
