Semi Automatic Water Level Controller Circuit Diagram. Note that this an example of wiring of water level controller the wiring of the controller can be different according to different types of automatic water level controller. The circuit is completely automatic which starts the pump motor when the water level in the over head tank goes below a preset level and switches off the pump when the water level in the over head tank goes above the full level.
Simple automatic water level controller the circuit works off a 12v battery or 230v ac mains using a 12v adaptor. The circuit uses 6 transistors 1 ne555 timer ic a relay and few passive components. The uln2003 can be effectively used for making a full fledged automatic 7 stage water level controller with indicator as shown below.
2 and connected to the circuit fig.

Margaret byrd published date. The circuit will automatically switch on any water pump motor when the level of water in a tank reaches below from the required level and automatically switch off the pump after filling the tank. This is a very simple water controller circuit built using the popular 555 timer ic.
