16f877 microcontroller, 2*16 lcd, 5 relays(for 5 levels) were used as basic. In the screen, the level of water is seen as symbol of % and graphical. It was designed as 5 levels but the numbers of levels can be enhanced besides there is an output for motor pump(12v) to fill water into tank, the motor is activated as manual but, it is be stoped again as manual or when the water is in last level (it means when the tank is full) it again stops.
This project is compeletely prototype, however with some chances, it can be used for real system(220 volt AC water pump)
