Light Sensitive Trigger System is a simple but powerful concept, which uses the IC555 timer as a comparator. When using this system, manual operations are eliminated at 100%. It automatically turns on the lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependent Resistor (LDR) that detects light really like our eyes. Automatically turns off the lights every time sunlight comes, visible to our eyes. When using this system, the energy consumption is also reduced because nowadays manually operated streetlights are not switched off even when sunlight comes on and also turn on before sunset. In this project, there is no need for manual operation such as the power-on time and the time-out setting.
