Nowadays energy sources are regulated and renewable energy sources are being used to meet the increase in energy demand. Because the price can be reduced by using the easily available energy. Besides the project is based on the minimum loss of available energy and the maximum utilization. During the daytime the solar cell will be collect the available solar energy and it is stored in battery. The stored energy is used to illuminate the street lamp at nighttime. This system provides an energy saving activity by the method of using automation. The automation method is based on sensors. The “ON”/“OFF” switch can be automated by using the sensors when a dark sensor and a light sensor provides the automatic “ON/OFF” facility to the automatic street lights. So that it will be glowing automatically when it is required. It is used again for auto intensive algorithm has applied with the help of microcontroller to control the intensity of lights as per the required. It can avoid energy loss due to the unwanted glow of the automatic street lights.
