LDR based Power saving system projects main idea is to develop a application which can control the electricity usage in street lights. LDR is used in this application for sensing light intensity. LDR controls power by controlling output resistance which is dependent on light intensity. Output form LDR is given to microcontroller and it controls output which is dependent on light intensity.

In existing system there is lot of wastage of power in street lights, in order to solve this problem this system will play important role. This application can also be used in industries, house hold applications and many other fields where power consumption is more.
