We face many problems when we use water pump every day life. Water spill unknowing of water level at the time of pump operation. run out of water when doing some thing such as taking bath. the objectives of this project is to find solution of problems associate with filling of overhead water tanks using electronic pump. Also knowing of water level of water tank. stop operation of pump when water get contaminated with such as mud.
Methodology
A micro-controller used as controller of the system. To measure water level a water level sensor based on electric conduction of water was used. these sensors were fixed on , lowest, highest and mid level of the tank. To sense impurities of water, a sensor to measure transparency of water is fixed at the entry point of water from the well. This sensor consist of LED bulb and photo-diode allowing water flow in between. also there is a water sensor about 6 inch above the water entry point of well, to sense presence of water.
A relay used to operate water pump. Water level, status of water pump and quality of water is displayed on LCD display.
