Most of the people in the context of our country, they are still using manual process for water pumping and motor control that used in home, office and industries. We will need two different power supplies, one for smooth running of microcontroller and another for input and optocoupler Optocoupler will be used to make circuit safe from outside signal. When all strip is dipped in water motor will off. Among different strips one will be connect with dc voltage, when water reaches and touches any of the strip the circuit is completed and respective Optocoupler is activated which gives will signal to microcontroller. In this project we will use self-make sensor which is consist of metallic strip. Beside the program logic and its functions, one important thing regard the level monitoring is its sensor. The programed logic in microcontroller gives the output which is connected the relay which controls the switching of the pump, using of siren and LCD to indicate the present condition of controller. the main control unit of the system which consist of the primary control switches. This circuit monitor the condition of water tank and control the motor used to pump water from ground tank to roof tank using microcontroller. Water level controller is automatic electronic circuit.
