Automatic Water Pump Controller….
(Developed for unnecessary ‘wastage’ and sometimes ‘non-availability’ of water)
Description . . .
It is a automatic water level controller circuit,it can automatically switch ON and OFF the domestic water pump set depending on the tank water level.It can implement this motor driver circuit at home or college using less costly components.the main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction.The approximated cost of the project is very less.
Challenges . . .
? Maintain a pre-determined water level when the water level in the tank goes low.
? Operation of controller works upon the fact that “water conducts electricity”.
? Glowing of LEDs,one can know water level in the tank.This LEDs can be mounted anywhere for easy monitoring.
? This circuit consumes very little power,always maintains a 12v DC power supply.
? Insulator stand of height greater than water tank height.
