As we all knows that nowadays, street lighting systems in industries and cities are increasing rapidly. There are  different technologies like electrical and electronics are cost effective, automation and power consumption.  These lighting systems are used to control and decrease energy consumption. This article illustrates the street light that glows on detecting vehicles movement.

COMPONENTS DESCRIPTION

 

RESISTOR

A resister is an electrical component that regulates  the flow of electrical current in an electronic circuit.

CAPACITOR

It is a two terminal electrical component used to store electric charges.

POWER SUPPLY

It is an electronic device that is used to supply electric charges to electrical load.

7812 LED

It has series of three terminal positive regulators fixed with several output voltages.

LDR SENSOR

A light depending resistor (LDR) is also known as photo resistors. It is a type of resistor whose resistance varies depending on the amount of light falling on its surface.

ULN2003

It is an array IC which consists of seven NPN darlington having high voltage and high current.

LED’s

A light emitting diode (LED) which emits visible light when electric current passes through it.

MICRO CONTROLLER 8051

8051 is an 8-bit family of micro controller its means that “system on a chip”.

WORKING OF THIS PROJECT

The infrared sensor are placed on each side of the road that are used to detect the vehicle movement and send the logic signals to the micro controller to turn on/ off the LEDs for a specific distance. The power supply of this project is made up of a step-down transformer, which steps down the voltage from 230v to 12V AC. This is transformed to a DC using a Bridge rectifier. A capacitor is used to remove the ruffel using a capacitive filter, and it is then regulated to +5V from 12v using a 7805IC voltage regulator, which is mandatory for the micro controller and for the other components too.

ADVANTAGES

Vehicle Movement Based Street Lights With External Light Sensing Project3-engineeringprayog

  • This project is designed to detect vehicle movement on highways to switch ON only a block of street lights before the vehicles and to switch OFF the behind lights.
  • It saves lots of energy.
  • low cost.

So now your Project is Ready ,Keep enjoying this project.

So, Friends I hope you understand this project very well . In upcoming Tutorial  I will be back with some new interesting Projects and we will discuss about some useful development topics. Here if you want to recommend that what I should write in upcoming Tutorial then please leave your comments. and if u need any help or query please don’t Hesitate to discuss with me. Thank You  🙂
