One day when I was in my native I found my grand father running fast to switch off motor since water is overflowing. I just stopped him and helped him to get it switched off but I worried in my absence they will be suffering there is a chance they may get hurt while running fast to switch off motor. I want to assure safety of my grandparents in my absence so I decided to look for a solution. Solution: Transistor based water overflow system where each level ( 25% ( red),50%( orange),75%( yellow) ,100%( green)) are indicated by LEDs. Whenever the tank is about to fill the Green LED glow along with beep sound indicates its time to switch off motor. Thus my grand parents and elderly people can switch off motor in a relaxed manner and we can prevent wastage of water.
