The objective of this project is to implement the system for power saving. This paper presents the implementation of the power saving system. For the power control system, detection method is used for a power ON/OFF automatically in respective place. There are four parts in this project: the solar panel power, voltage switching source, sensor stage, and the energized relay portion. In the supplying power, sensor unit is employed for switching stage. The heart of this project is sensor portion. The sensor unit consist the LDR (Light Depending Resistor) the PIR (passive infrared sensor). The task of LDR is to detect the approaching of human person based on the principle of light/dark sensing. PIR sensor detects the radiated heat of a person and these data converts to an electrical signal and this signal is sent to the switching for processing. This signal creates a specific voltage for the relay to activate the power switching. But nobody is detected the power is automatically turned off. As a consequence the constructed energy control system prevents energy wastage.
