The automatic street light control is designed to switch on and off street lights automatically. This project checks the amount of light. If light is 80 percent available, it automatically turns off street lights. But if the amount of light is less than 80 percent, this project will automatically turn on the street lights. One can also adjust it according to your requirement. The light sensor is used to detect the intensity of light. PIC161F877A microcontroller interface is used with the light sensor to detect the amount of light available. The control signal is generated with the help of the microcontroller pic16f877a after analyzing the amount of light. The control signal generated by pic microcontroller is used to activate the transistor which in turn energize the relay coil and the relay turn on the street light. I have used only one lamp in this project. Because this is for demonstration purposes only. To use it practically, you can use as many street lights as many that you want to control through this automatic control of street lights.


The idea of designing a new system for the lamp that does not consume large amounts of electricity and illuminate large areas with the greatest intensity of light is on every engineer working in this field. Providing street lighting is one of the most important and costly responsibilities of a city. Lighting can represent 10-38% of the total energy bill in typical cities around the world. Street lighting is a particularly important concern for public authorities in developing countries because of its strategic importance for economic and social stability. Inefficient lighting is wasting significant financial resources each year, and lack of lighting creates unsafe conditions. Energy efficiency technologies and design mechanism can drastically reduce the cost of street lighting. Manual control is prone to errors and leads to energy wastage and manual darkening at night is impractical. In addition, dynamic tracking of the light level is manually impracticable. The current trend is the introduction of automation and remote management solutions to control street lighting. There are several numbers of control strategy and methods in the control of street lighting system as the design and implementation of CPLD-based solar energy saving system for street lights and automatic traffic controller, design and manufacture Automatic street light control system, and road safety module with integrated system, automatic street light control system, intelligent street lighting system with Gsm, energy-saving solutions based on intelligent control system Street lighting and a new design of an automatic lighting control system for a network of wireless sensors with increased sensor Life-levels and reduced sensor  . This document will use two types of sensors that are light sensor and photoelectric sensor. The light sensor will detect the darkness to activate the on / off switch, so the street lamps will be ready to light and the photoelectric sensor will detect movement to activate the streetlamps. LDR, which varies according to the amount of light falling on its surface, this gives an induction to know if it is a day-night, photoelectric sensors are placed on the side of the road, which can be controlled by PIC16f877A microcontroller. The photoelectric will activate only at night. If any object crosses the photoelectric beam, a particular light will automatically turn on. Using this as a basic principle, the intelligent system can be designed for the perfect use of lampposts anywhere.
