Hi , all i need you to help me making a small project to control the pump of water to make it switch on and off automatically , any one has any idea about the circuit diagram and component pleas replay .
Thank you 3v0 , look my circuit should be complately electronics ,by means of transistors and relay and logic circuits and IC's . there should be two sensors one for high level and the other for low level .
Where does the water come from you want to move? In some areas city water supply slowly fills a reservoir (mostly at ground level), which is then pumped into an overhead tank.
You certainly wouldn't like your pump running dry, so this has to be considered when designing a control device.
The pump activation also depends on your desires, meaning do you want to activate the pump if the water level in the overhead tank is not at maximum and there is water in the reservoir, or do you want to activate it if the water level in the overhead tank is down to minimum or 1/2 filled?
Hi MR Boncuk, consider the paremeter that you taked about were cared ,
i need to activate the pump only when the water at the low level and switch it off when the water at the high level , don't take care any other parameter, i need the electronic circuit diagram and the name of component that will do the job .
