Abstract This project Automatic Street Light Control System aims at designing and executing the advanced development in embedded systems for energy saving of street lights by using light dependent resistor (LDR). Nowadays, human has become too busy and he is unable to find time even to switch the lights on or off. This can be seen more effectively in the case of street lights. The present system is like, the street lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timing for these street lights to be switched on are when there is absolute darkness on the roads. This project gives the best solution for electrical power wastage. Also the manual operation of lighting system is completely eliminated. In my project using LDR, which varies according to the amount of light falling on its surface; this gives an indication for me whether it is a day/night time. This project can be configured by using transistors, IC 555.
