This document describes a student project to develop a street light energy saving control system. The system uses an Arduino nano, infrared sensors, LEDs and an LDR to dim streetlights when no vehicle movement is detected, in order to reduce energy consumption. When an IR sensor detects a vehicle, the LED streetlights in that area will glow at full intensity, and then the next block of lights will turn on as the vehicle moves forward. The system aims to save electrical power by only keeping streetlights dimmed at 40% intensity when roads are inactive. The document outlines the methodology, hardware components, software, results and applications of the smart streetlight control system.

3. ABSTRACT
In this project the system is to develop a street light energy saving control
system to reduce energy if no vehicles pass through certain roads.
The proposed system saves a large amount of the electrical power. In addition,
it may increase the lifetime of the lamps.
Operation of this system is to maintain the intensity of street lighting to 40% of
the maximum intensity if no vehicles passing through the road.
The prototype for the street lighting energy saving control system is also has
safety usage that is the light will not turn OFF completely but only dimming
and the user can easily see from far away and the light will full turn ON if it
detecting movement.

4. INTRODUCTION
 Street lights are an essential part of all cities and the highways, that’s helpful to
prevent accidents and unwanted thefts or robbery.
 Thousands of Street lights are installed beside the highways and the main roads. But
the main problem is these street lights consume about 25-30% of the total energy
spent in the city.
 In this project, our main aim is to develop a “Smart Street light system” that will
reduce electric power consumption.
 The normal street lights always glow with high intensity, who consumes high
electricity.
 But in the case of a smart street lights system, it will glow with high intensity if
there are vehicles or human movement on the road otherwise the lights will remain
dim.

6. METHODOLOGY
The Smart street light control system adopts a dynamic control methodology.
According to the proposed plan, initially when it becomes dark .
Vehicle or human movement passes by a block of street light then that block of
street light glows.
When the vehicle or human moves forward, the next block of street light
glowing where the previous block switched off.

8. EXPALANATION OF BLOCK DIAGRAM:
 When we observe from the block diagram when humans or vehicles move
on the road IR sensor senses the movement and give the signal to Arduino
nano.
 Arduino nano send signal to LED’s to turn ON and glow only when at the
night time by using LDR.
 LDR is alight dependent resistor so when there is a sun light presents the
LDR gives the signal to Arduino to turn OFF the LED.

10. HARDWARE REQUIREMENT
 ARDUINO NANO
 IR SENSOR
 LED’S
 LDR

11. The Arduino board is designed in such
a way that it is very easy for beginners
to get started with microcontrollers
ARDUINO NANO
IR SENSORS
An infrared sensor is an electronic device, which
emits in order to sense some aspects of the
surroundings. An IR sensor can measure the heat of
an object as well as detects the motion. Usually in the
infrared spectrum, all the objects radiate some form
of thermal radiations.

12. LED’S
 A light-emitting diode (LED)
is a Semiconductor light
source that emits light when
current flows through it.

13. LDR
 LDR are light sensitive devices, it is also
known as photo resistor, that works based on
electromagnetic radiation.
 When the light falls on the LDR, its resistance
drops and current flows into the base of the
first and second resistor.
 When LDR are kept in dark, the resistance is
high.

14. SOFTWARE DESCRIPTION
 ARDUINO IDE
Where IDE stands for Integrated
Development Environment – official
software introduced by Arduino.cc that is
mainly used for writing, compiling and
uploading the code in the Arduino Device.

15. RESULTS
The project in the figure has been
implemented and works as expected and will
prove to be very useful.

16. ADVANTAGES
 Automatic switching ON and OFF of street lights, so there is no need of manpower.
 Cost-effective.
 Maintenance cost is less.
 Power saving.

17. DISADVANTAGES
 Implementation cost is high.
 In case of defect or repair, troubleshooting of the system is complex.
 System is subjected to damage by environmental conditions.

18. APPLICATIONS
 It is used for digital signage.
 It could also be equipped with charging station for electric vehicles.
 Highways, parking lights, garden lights etc.

19. CONCLUSION
 If we use this idea and implement it into our society it will be very useful in saving
enough amount of electricity and ofcourse money.
 The energy will be conserved and given to the next generation.
 This idea & implementation will also conserves the natural resources.

20. FUTURE SCOPE
 An smart street lighting system can cut municipal street lighting costs as much as
50% - 70%.
 These smart lights will help cities reduce electricity costs and improve maintenance.
 In addition to enabling cities to provide the proper amount of street light for local
conditions, installing smart lighting will help improve citizen satisfaction regarding
security and safety, while bringing municipalities significant savings in power
consumption and lighting system maintenance.
