The light sensor converts light input into corresponding electrical output. It is used in automatic street light system, automatic brightness control in mobile, and security devices in home and offices, which helps in minimizing the power consumption of the devices. Most commonly used light sensors are based on photo resistors, which control flow of current using sensed light energy. These are known as Light Dependent Resistors (LDRs). Еще
