Automatic Street Light for night using 555 timer and LDR.

Simulation of automatic street light

PCB Layout

Conclusion

There were two goals for the project: to lessen the negative consequences of the present street lighting system, and to find a way to conserve energy. The first step in this project is to set up the inputs and outputs of the system that will be used to control the street lights, which will take some time.

This study elaborates the design and installation of automated street control system circuit. Circuit works perfectly to turn street light ON/OFF. After creating the circuit which controls the illumination of the street as demonstrated in the previous sections. LDR sensor and the photoelectric sensors are the two basic conditions in functioning the circuit. If the two requirements have been met the circuit will conduct the needed task according to particular program. Each sensor regulates the turning ON or OFF the lighting column. The LEDs have been successfully controlled by 555 timer. With orders from the sensor, the lights will be ON at the areas of the movement while it's dark. moreover, the problem of the street light system employing timer controller has been eliminated, where the system relies on photoelectric sensor. Finally, this control circuit may be employed on a lengthy route between the cities.
