The main objective of our project Density Based Advance Traffic Light System with 8 sensor using 8051 is to provide more advance facility at red light crossing. Normally there is traffic system in which each side gets green light for fixed time then red light gets on whether there is any traffic presence or not on that side. And traffic on other sides has to be waiting which waste of time. So, we provide an idea to overcome this problem. In our system there are total eight sensors, two at each side which detects the traffic on each side. The first sensor on each side tells to the system that there is any traffic or not. If system knows that there is no any traffic the side where the green light is going to be on, then it switches to the next side without wasting of time.

If first sensor gives presence of traffic on that side then system checks the second sensor of that side which gives an idea of crown that side. If second sensor gives the presence of traffic then system provides the green light twice of regular time (say 2 min) on that side. Otherwise, it provides green light for regular time (say 1 min). By apply this system in our red crossing traffic light we can reduce the accident on crossing road. Our advanced traffic light system can easily apply on the real life. This system is controlled by AT89S51 (8051 family) micro – controller with help of eight sensors.


  1. Sensors used are easy to handle.
  2. It clear traffic in less time.
  3. It decreases waiting time on traffic light while there were no or less traffic on rest sides.
  4. It automatically controls the traffic light according to congestion by providing proper time for green light.
  5. Low maintenance and low power consumption.
  6. Labour saving.

How To Choose Best kit for You

1. Professional Kit

this kit for Professional person who knows project soldering, testing, assembling and some basics knowledge. In this kit our role is to provide PCB fabrication, microcontroller programming (If any), Project designing and documentation. Our responsibility is limited to according to checklist facilities only. User is responsible for further process like soldering, assembling etc to complete the project. (Do it yourself 70%)

2. Assembled kit

this kit is fully assembled and tested by us for final running. It has prepared for instant requirements and Ready to Use

3. Combo Kit

there are two separate kits, one fully assembled and tested kit. The second one is a Designed & Drilled Copper PCB with soldering components except a set of detachable components which is already attached in first kit (assembled). User can complete the second kit according to assembly procedure given by us in their college practical lab. If user could not complete their project then he/she can use our first kit or make correction by analyzing and comparing with first kit. (Do it yourself 50%)

4. Learning Kit

this kit is fully Do it yourself under our live guidance & support at our workshop or online video calling. We guide how can component has to be place on PCB and solder to it. We continuously checks and guide if any mistaken by user step by step till completion of project. And after successfully completion of project we certify to student that he/she complete their project successfully in our guidance and also provides our company certificate for this.
