The document outlines a project for a smart street lighting system developed by a team of students, aimed at minimizing power loss during nighttime by adjusting the intensity of street lights based on activity detection. The system utilizes an IR transmitter-receiver pair and a microcontroller to control the lights, with programmed responses based on light and motion sensors. The main outcome is a reduction in energy wastage while maintaining adequate lighting based on road activity.

Smart Street Lighting System

2. Objective/problem description:
 To devise a smart street lighting system which aims
at curbing the power loses during night time.
 It is Achieved by Reducing the Intensity of the Street
Lights when the street are empty and increasing it
when activity is detected.
Methodology:
 Connecting the IR transmitter-receiver pair and LDR
circuit to the microcontroller .
 Connecting the microcontroller to the LED’s (Street
light) via a LM324(Amplifier) assembly (to control light
intensity and amplify the voltage).
 Basic Programming of the microcontroller
Case1: if LDR=true(day) then, microcontroller pin(OFF)
Case2: if LDR=false(night)&&IR=true(motion) then,
microcontroller pin(high)
Case3: if LDR=false(night)&&IR=false(no motion) then,
microcontroller pin(low).
• Executing and running the program.
Main Result/outcome:
• Reducing the amount of energy wasted
by curbing the power losses in the street
lamps during the night time.
• Smart detecting system to adjust the
intensity of street light according to the
activity on the road.
