Smart Street Light System

Project Title

Smart Street Light System

Project Area of Specialization Wearables and ImplantableProject Summary

Project Summary:

Statistics show that almost three-fourth of the demands of energy in the world is fulfilled by fossil fuels. Since fossil fuels are hydrocarbons, burning fossil fuels releases a large amount of carbon dioxide into the air. This increased percentage of carbon dioxide causes global warming. Combustion of fossil fuels not only emits carbon dioxide into the air, it also releases other gases like carbon monoxide, methane, nitrous oxide, etc. that cause air pollution. To avoid this we have to reduce wastage of electrical energy and try to produce energy through other means instead of using fossil fuels. Currently, enormous amount of electrical energy is being consumed by the street lights, which remain switched on throughout the night. This causes a huge waste of electrical energy across the world and should be prevented. The main aim of smart street light systems is that lights turn on only when there are vehicles or pedestrians on the road and remain off otherwise. The street lights will be powered by the electrical energy generated through the pressure applied by footsteps and vehicles. So we don’t need to provide power to the street lights by energy from fossil fuels which are being depleted due to their increased demand.  The smart street light system consists of DC lights, LDR, piezoelectric sensors, motion sensors and short-distance communication networks. Our main purpose is to reduce wastage of energy and make use of non-conventional sources for energy production.

Project Objectives

Project Objectives:

Our project has the following objectives:

• The lights will be powered by energy produced by pressure applied by footsteps of pedestrians.
• We will use DC lights instead of AC lights to eliminate cost of conversion of DC to AC.
• Control energy efficient street lights to turn on only when needed and remain off otherwise
• This project will help to decrease wastage of electricity by controlling working of smart street light system that contributes to a good amount of electricity bills in our nation
• Smart street light system tries to find solution for faster depletion of energy resources due to inefficient usage and wastage of these resources
• Build an energy saving smart lighting system with integrated sensors and controllers.

Project Implementation Method

Project Implementation Method:

As in this project we have two stages. In the first stage we will produce energy through non-conventional sources of energy i.e. the electrical energy produced by pressure applied by footsteps and this energy will be stored in battery and utilized by powering the street lights and in the next stage we will save energy as the lights will turn on only when there is motion on the road. To implement this we will place sensors below the tiles which will be on the footpath, when the pedestrians walk on footpath energy will be generated and this energy will be stored in battery and then be utilized to power the lights. We will place a motion detection sensor on the light pole so the lights will only turn on when there are vehicles or pedestrians on the road.

Benefits of the Project

Benefits of the Project:

• Power is generated by walking on the footpath.
• No need of external power source to power the street lights
• Minimize power consumption
• Eco friendly
• Reduce energy cost
• The battery is used to store the generated power

Technical Details of Final Deliverable

Technical Details:

In this project, the street lights will turn on only when there is motion on the road and remain off otherwise. For this purpose we will use PIR sensors that detect a human being or vehicles moving around within approximately 10m from the sensor. This is an average value, as the actual detection range is between 5m and 12m.We will also use piezoelectric sensors to generate electricity. Piezoelectric sensor utilizes the piezoelectric effect, to measure changes in acceleration, strain, pressure, and force by converting them into electrical charge. The sensors will be arranged in series and parallel combination below the tiles used to make the footpath. This will produce AC voltage, which will be converted to DC voltage and stored in 12V battery. We will then use this energy to power the street lights which has DC bulbs of approximately 5W power.
