DESCRIPTION OF CIRCUIT & COMPONENTS

1.Transformer-: To step down voltage from 230v to 12v(A.C).2.Rectifier-: Bridge rectifier is used to convert 12v ac into

D.C.3.capacitor-: To filter the rectifier output supply.4.AN7805-: To get regulated 5v dc supply for controller.5.8051(microcontroller)-: to sence the position of magnetic

sensor.6.crystal-: it is use for controller operation.7.Magnetic sensor-: It is just a switch . When magnet comes

near it, the sensor switch will be close.

8.BC547(transistor)-: it will give the 12v d.c. current to the relay when it gets the signal from microcontroller.9.SPDT relay-: It will switch the motor when it gets the power from transistor.10.resistor-: to limit the base current of BC547.11.motor+pump-: to suck the water from the ground and send it for fill the watertank.

Application-:

1.This system can be used anywhere ,where water pump are used to fill the watertank.

For example-:-residential buildings-Municipality water supply service-industries

Advantages-:

1.Fully automatic service , so there is no need of mankind.

2.Low power consuption circuit.3.Easy to construct.4.Low coast.5.Reliability6.Less chances of failure
