Solar Highway Lighting System with Auto Turn Off in Daytime
The project is designed for LED based street lights with an auto-intensity control that uses solar power from photovoltaic cells. Photovoltaic panels are used for charging batteries by converting the sunlight into electricity. A charge controller circuit is used to control the charging, and an LDR is used to sense the ambient light on day time.
The intensity of street lights is required to be kept high during the peak hours. As the traffic on the road tends to decrease slowly at late nights, the intensity also gets reduced progressively till morning to save energy. Besides the same street lights are switched on at the dusk and then switched off at the dawn automatically by using an LDR sensing device LDR. The process repeats every day.
High Intensity Discharge lamps (HID) generally used for urban street light are based on the principle of gas discharge and thus the intensity is not controllable by any voltage reduction method as the discharge path gets broken.
LED lights are the future of lighting, because of their low energy consumption and long life they are fast replacing conventional lights world over. White light emitting diode (LED) replaces the HID lamps where intensity control is possible by pulse width modulation.
The intensity control helps in saving energy during late nights while traffic density on the street is low. A programmable microcontroller of the 8051 family is engaged to provide different intensities at different times of the night using PWM technique, for energy saving for solar based system, also using a charge controller for protecting the battery from over charging, overload and deep discharge protection. A light sensing device LDR (Light Dependent Resistance) is used , whose resistance reduces drastically in day light for sensing purposes.
Furthermore, the project can be enhanced by using time programmed dusk to dawn switching based on latitude and longitude of a specific location .

Get 100% Assured Successful Results
A simple and effective plan that assures you the best scores, a plan that gives you time to read, learn, practically experience the whole workings of your project and create a successful unit you can proudly showcase. And the best part is this… even if your own project unit malfunctions... you will still have a ready-made project unit for yourself, just in case there is a last minute issue that you or your teammates could not solve. Confused? Well let me explain.
Plan A: Create A Successful Project Model By Yourself
Plan B: Have A Expertly-Made & Quality-Tested Replica Of Your Project For Assured Results
So here’s how it works.
In my engineering days, we used to struggle replicating a PCB model from our text books with real tools. We had a tough time with the circuits and most of the time - they used to fail. So I wanted to solve this problem not just for myself but for all my fellow students like you. Young, energetic and knowledgeable youth who really want to learn but still cannot afford to fail with the project because it matters and the colleges rarely help us out productively.
So I want to give you a beautiful DIY model of the project that also includes:
- A Complete set of tools, circuit diagrams, tested PCD, zero board, audiovisuals and everything else you will need to execute your project to perfection.
- A ready-made unit of the project itself, so that you can actually see, test and learn in real-time and if by any chance you could not complete the unit by yourself - can submit this unit for an assured first-class score.
Sounds like a dream? Well, yes it is and here’s how you can benefit from this project not just in your final year but also help you with your interviews and in the future too.
"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "Ravi Teja

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "Anusha

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"Mr. Ramesh Kumar Jha
