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.
A switch can simply be defined as a device powered to turn the electric current on or off. Switches are important devices in electrical and electronic circuit design. Therefore, they are widely used components that serve today as control devices in modern electrical systems and circuits. The switches may also be defined as devices by which a circuit or signal parameter such as electric current may be linked or cut from another part of a circuit manually or automatically.
