IMPLEMENTATION OF SOLAR WATER PUMP CONTROLLED WITH FOUR DIFFERENT TIMES FOR POWER SAVING APPLICATIONS

ABSTRACT:

Form olden days we re using non renewable sources of energy in excess mount  for  our needs. As this type of minerals like coal etc are exhausting so we have to depend on the renewable sources of energy like solar, wind, etc. For smaller application it is better to use renewable energy.

As this project is based on streetlight automation and required Ac supply. So for this particular application we are using solar panels to charge the DC battery and the power from the battery can be used for this application.

This project is an innovative solution to operate a machine / motor / liquid pumps for a small duration. If a machine is to be operated for ten minutes, and should be switched off after the duration, it is too difficult and many times we forget to switch it off the system after the prescribed time.

This project provides the facility of automatic switch off after the requited time duration. This is achieved by using the MCU. Four push-to-on switches are connected to one port of the microcontroller. These four switches are to provide four different fixed time constants.

A  16X2  LCD  is  connected  to  the  microcontroller  to  display the  status  of  the  pump. Contrast of the LCD can adjusted by using a preset which is connected to it.

A transistor is used to drive the relay during the active time period. 5V double pole - double through relay is used to control the AC liquid pump. LED indication is provided for visual identification of the relay / load status. A switching diode is connected across the relay to neutralize the reverse EMF.

ADVANTAGES:

1.      Power can be saved

2.      Decreases the man power

APPLICATIONS:

1.      Agriculture

2.      Industries

3.      Homes
