PIC based Traffic Light Control using Solar Panel Mr. Sangram Pawar1 Mr. Ganesh Chavan2 Mr. Abhishek Oran3 Prof. N. S. Ukirade4 1,2,3 Student 4Assistant Professor 1,2,3,4 Department of Electronics & Telecommunication Engineering 1,2,3,4 DACOE, Banawadi, Tal-Karad, State-Maharashtra, Country-India Abstract— Solar traffic light is having some benefit and drawback. The solar powered traffic light control system is making very suitable work. Main use of this traffic control system it's not create the wiring complexity and other electric work. For the road safety and traffic management system. It is matched with latest technology electronics. On the top of the pole this solar panel is situated. It is used for the converts sunlight into electrical power. The main problem of each city is electric power then by using this technology to save the electric power in some part. The main purpose of solar traffic light is to keep flowing the traffic during power cuts. Further the detectors are useful in this project. At night it detects for no vehicle then signal is off.

II. SOLAR PANEL The figure shows solar panel that had been used in this project. The solar signal was founded by the experts. The solar panel is working to collect the ray's coming from the sun. By the source of energy it generates electricity and heat. The solar panels having some measure mounted on the main pole directly above or next to head of two each signal.

The mast arm hangs over the road way typically eight meters and the air making theft nearly impossible

I. INTRODUCTION We introduces many interesting but important things in solar powered traffic light control .It is based on three type of colours in LEDs light signal. Some fact about Solar LED based Traffic light the benefits and losses of project, problem statement, objectives and the future of project. we have to create new facilities at this time make it very easy.

Nowadays more facilities comes in the world so that the reason we need to change the system. Therefore some cities are making to manage their transportation systems to improve it.

Fig. 1: Solar LED based Traffic Light Signal The solar based traffic light is produced by solar power at only daytime and at night time using charging the battery for backup. The advantage of this project is no trenching to do for stick upright the pole of traffic light. It is also no wiring from power supply to connect at the pole traffic light. The small LED's are used in this system but it produce bright light. The solar based traffic light is placed on top of the pole and it is portable system. For using this technology save the electricity and good for environment the maintains for this technology is not costly. It becomes problem to functioning the traffic light at night time when the battery was not fully charging during daytime. For rainy and cloudy season, the solar panel not working properly because solar rays not receive.

Fig. 2: Solar panel The silicon cell with highest efficiency is the mono-crystalline cell, where the atoms are symmetric placed within the structure. However it is also very costly to manufacture this symmetric structure. Commercial silicon cells have an efficiency of 14 - 17 %. A less expensive alternative is the polycrystalline cell, where the structure is less symmetric and less complex. This has an efficiency of about 13 - 15 %.

Another type of silicon solar cell is the thin film cell based on amorphous silicon that is sprayed on a transparent surface. Because of the low amount of silicon needed, the required energy for manufacturing and thereby the production cost of those cells can be very low. The expectations are high and in laboratories efficiencies of around 13 % have been reached

Table 1: Specifications III. CIRCUIT DIAGRAM In this circuit diagram the main device is solar panel and PIC16f877 microcontroller. The solar panel is provide the electricity and store the energy in battery. If the monitored voltage is above 12v the battery used to supply the voltage to PIC16f877 microcontroller.

regulator. Then they connected to the power supply it create three output.first is connected to PIC 16f877 microcontroller and another is traffic lights and display IV. CONCLUSIONS Based on the solar panel and PIC this design is properly successful. The benefit of the traffic control system is the proper use of solar energy in a well manner. It having only purchase cost then not for the utililization. This initiative will help the government to save this energy and meet the domestic and industrial needs. This projects it beneficial to the government for the save the extra work of the electricity.

This solar powered traffic control system is making the project very suitable.

Fig. 3: Circuit Diagram PIC 16f877 having connected to the four port. Port 1 is attaching to the three transistor. Similarly another three ports are connected to three LED signals.In this way the connection of solar powered traffic signal are briefly explain in the circuit diagram and the output of the traffic light signal based on program is designed.

A. PIC 16F877 PIC 16F877 is a 40-pin 8-Bit CMOS FLASH Microcontroller. 16F877 comes with 3 operating speeds with 4, 8, or 20 MHz clock input. Since each instruction cycle takes four operating clock cycles, each instruction takes 0.2 μs when 20MHz oscillator is used. It has two types of internal memories: program memory and data memory.

Program memory is provided by 8K words (or 8K*14 bits) of FLASH Memory, and data memory has two sources.

One type of data memory is a 368-byte RAM (random access memory) and the other is 256-byte EEPROM (Electrically erasable programmable ROM).

The core feature includes interrupt capability up to 14 sources, power saving SLEEP mode, and single 5V InCircuit Serial Programming (ICSP) capability. The sink/source current, which indicates a driving power from I/O port, is high with 25mA. Power consumption is less than 2 mA in 5V operating condition.

Fig. 4: Block Diagram The solar panel used to convert the sunlight energy to produce electricity and then store electricity to battery.

The battery is used to supply the voltage PIC microcontroller and at the same times it charging for appliance at the night time. Form the microcontroller; it has been produce the output at the traffic light signal board based on program that designed.

At first solar panel is connected to the battery further the output of battery is regulated using the voltage

ACKNOWLEDGMENT This is a small gesture and gratitude that we can express for the immense help rendered to us by our guide Prof.

N.S.Ukirade for suggesting, guiding and exhibiting keen interest in the project work. Without her guidance and supervision right from beginning it would not have been possible.
