Design And Construction Of A Street Lights That Glow On Detecting Vehicle Movement

Electrical Electronics Engineering | Industrial Physics | Physics

The development and implementation of an intelligent street lighting system that illuminates upon detecting vehicle movement involves a sophisticated integration of sensors, microcontrollers, and light-emitting diodes (LEDs). This innovative infrastructure harnesses motion detection technology to activate the street lights, enhancing energy efficiency and promoting safety in urban environments. By leveraging sensors strategically positioned along roadways, this system can swiftly identify the presence of vehicles, triggering the illumination of LEDs along the path of movement. The construction phase encompasses the installation of these sensor nodes at optimal locations, ensuring comprehensive coverage of vehicular activity. Additionally, the design incorporates microcontrollers programmed to interpret sensor data and activate the corresponding LED modules effectively. Through meticulous engineering and meticulous calibration, this intelligent street lighting solution not only conserves energy by illuminating only when necessary but also enhances visibility for both motorists and pedestrians, thereby fostering safer and more sustainable urban communities.

ABSTRACT

Generally, street lights are switched ON for whole night and during the day, they are switched off. But during the night time, street lights are not necessary if there is no traffic. Saving of this energy is very important factor these days as energy resources are getting reduced day by day. Alternatives for natural resources are very less and our next generations may face lot of problems because of lack of these natural resources. This circuit switches the street lights on detecting vehicle movement and remains off after fixed time.

INTRODUCTION

1.1 BACKGROUND OF THE STUDY

The idea behind the design of this system is to make available the require illumination in our roads for nighttime events, security, and beautification. This goes a long way in helping to curb the problem frequently encountered as a result of darkness during nighttime such as thieves, arm robbers operations or wide animals approaching our homes during night hours.

A street lighting is any electrical lighting that is fixed outside house for the illumination of such environment or a Street light is a raised source of light on the edge of a road or walkway, which is turned ON or lit at a certain time every night.

Many of the people have a phobia of darkness, so to assist them in such situation; we have explained a simple circuit. This device switches street lights on detecting vehicle movement and remains off after fixed time.

1.2 PROBLEM STATEMENT

Lack of natural light during nighttime in the urban environment was always a problem due to natural law – light in the day and darkness at night. From basic inconvenience that people cannot see where they are going to the greater chance of being attacked or mugged during the night. Street light came to bring solution to this problem, street light electrifies our environment for easy and clear access and also add beauty to it.

1.3 OBJECTIVE OF THE PROJECT

The main objective of this work is to construct a street light that switches ON when detecting vehicle movement and remains off after fixed time. This work is built around Atmega8 microcontroller, LDR, PIR sensor and RTC.

Objectives:

The main objective of this project is that to make a device which controls the ON and OFF process of street
The another objective of this project is that to reduce the wastage of electricity on a large
It will reduce the work of human being and help us to manage the

1.4 SIGNIFICANCE OF THE STUDY

Major significance of street lighting includes: prevention of accidents and increase in safety. Studies have shown that darkness results in a large number of crashes and fatalities, especially those involving pedestrians; pedestrian fatalities are 3 to 6.75 times more likely in the dark than in daylight. Street lighting has been found to reduce pedestrian crashes by approximately 50%.

Furthermore, lighted intersections and highway interchanges tend to have fewer crashes than unlighted intersections and interchanges.

Towns, cities, and villages use the unique locations provided by lampposts to hang decorative or commemorative banners.

This circuit uses LED Bulbs, so it is very low cost and it has more life span.

Maximum energy can be saved.

1.5 PURPOSE OF THE STUDY

The main purpose of having an automatic street lighting at roads is for lighting up your road automatically – for beautification, safety and security.

By using this Automatic system for street light controlling, we can reduce energy consumption because the manually operated street lights are not switched off properly even the sunlight comes and also not switched on earlier before sunset.
In sunny and rainy days, ON and OFF time differ noticeably which is one of the major disadvantage of using timer circuits or manual operation for switching the street light system.

1.6 APPLICATION OF STREET LIGHTING

This circuit can be used in real time street lights and highways also.
This can be used for lights in parking areas of industries, hotels, restaurants, etc.

1.7 TYPES OF LAMPS USED FOR STREET LIGHTING

Ballast: Ballast is an auxiliary piece of equipment designed to start and properly control the flow of power to discharge light sources such as fluorescent and high intensity discharge (HID) lamps. Some lamps require the ballast to have thermal protection.
Fluorescent light: A tube coated with phosphor containing low pressure mercury vapor that produces white light.
Halogen: Incandescent lamps containing halogen gases such as iodine or bromine, increasing the efficacy of the lamp versus a plain incandescent lamp.
Neon: A low pressure gas contained within a glass tube; the color emitted depends on the gas.
Light emitting diodes: Light emitting diodes (LED) are solid state devices that emit light by dint of the movement of electrons in a semiconductor
LED lamps have been advocated as the newest and best environmental lighting method. According to the Energy Saving Trust, LED lamps use only 10% power compared to a standard incandescent bulb, where fluorescent lamps use compact 20% and energy saving halogen lamps 70%. The lifetime is also much longer — up to 50,000 hours. A downside is still the initial cost, which is higher than that of compact fluorescent lamps.
Compact fluorescent lamps: CFLs are designed to replace incandescent lamps in existing and new installations.
