Smart Home Light Intensity Control using Potentiometer method for Energy Conservation

This paper mainly focus on energy saving to reduce pollution using potentiometer method. There is a need to control the energy consumed by lamps in households and colleges in day time. A smart device based light intensity controlis done by using Arduino and potentiometer. According to consumer requirements they can change amount of light intensity by using simple potentiometer. Based on potentiometer set value and signal from zero crossing detector circuit Arduino receives the input signals and it generates a signal based on code given to it to the firing circuit of TRIAC to control the firing angle thus to control the voltage across lamp to get required brightness and it is simulated using proteus software. Proteus software is best tool to run Arduino based circuits in real time. Based on calculations energy consumption due to lightning units can be saved up to 10% by using this method.
