Abstract : In this model we show that how we can generate a voltage from the busy traffic. Conversion of the mechanical energy into electrical energy is widely used concept.
Itís a mechanism to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into rotational energy.
We have used that simple concept to the project. We connect one mechanical rod with the dynamo and fit this rod on the surface of the road.
When any vehicle moves from this roller then due to friction, vehicle Rotate the rod or roller and roller then move the dynamo.
When dynamo move then it generates a voltage and this voltage now connects to the bulbs.
In actual practice with the help of this voltage we will charge the battery and then we use this voltage to light the small bulb.
If we install this unit to the any small flyover then with the help of this voltage we generate a small voltage, and with the help of this voltage we light the bulb.
The second part of that project is an efficient use of energy by using simple electronics.
We always see that road light continuously glow whether vehicle on path or not. We have introduced a concept to avoid a waste of light.
We have used two sensors between some distances. When vehicle pass through first sensor it sends the signal to the microcontroller that the vehicle is passing along that particular distance then light will glow for that particular time and when vehicle goes out from the second sensor.
Then the second sensor sends a signal to a microcontroller that vehicle has been passed through that particular path then light gets off automatically.
Different types of basic electronics components has been used to get the desired output like capacitor, resister etc.
We have also used a light diode resistance(LDR) when LDR senses a light around it all the road lights gets off and when LDR senses there is a dark around it then LDR sends a signal to microcontroller then all the road lights gets on.
By using a LDR we can avoid a waste of light that glow in a day time. The two sensors are made from the concept of electronics.
These sensors are called an infrared sensor which is made from photo diode and light emitting diode each.
When any vehicle pass from first sensor then first sensor becomes on, for that time the road lights gets on and when it pass from second sensor the second sensor become on and the first sensor gets off then the road light gets off.
