Occupancy based Street lighting System

Published on 20 May 2022. Written by Tej Kumar

Right now the entire world has taken steps to reduce the wastage of power. You may have observed that during night time whether anyone present on the road or not, the street lights will glow continuously for the entire night. Now imagine that there is a system where whenever someone is walking through the street, immediately Street lights are turned on and as soon as the person left the street, the street lights will be turned off. Through this project, you are going to build an autonomous street Lighting system based on occupancy.

You will need Arduino to interface the microcontroller with the Relay, Wi-Fi module, and Triac circuit. You will programme the microcontroller in such a way that whenever the IR sensor detects the vehicle on the road, immediately the Streetlight will be turned will be turned on and similarly whenever the IR sensors don’t detect the vehicle, immediately the Streetlight will be turned off. You can innovate the system to upload the data regarding Street light status into a remote server for further analysis.

Project Description:

Arduino Uno: The digital and analog input/output pins equipped on this board can be interfaced to various expansion boards and other circuits. The serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
Wi-Fi Module: ESP8266 Wi-Fi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter
N-Channel Relay Module: The n-Channels Relay module’s operating voltage is 5V DC with drive current of 20mA. This relay can be interfaced with many no. of microcontrollers such as Arduino, AVR, PIC, ARM, and MSP430. Here we use Arduino, because programming is not that much typical. This relay module has ports “NC” abbreviated as “Normally connected to COM”, “NO” abbreviated as “Normally open to COM” and “COM” abbreviated as Common. Along with these, there will be two types of LED’s, one is to show the power status of the board and other for showing the relay status. Here “N” indicates the no relays on single board. We have 2, 4, 6, 8, 10, 12-Channel Relay Module are available in the market.
IR Sensors: The component we use to find whether there is any vehicle going on the road is called IR sensors (Infrared).

Project Implementation:

Interface the Relay and IR sensors with Arduino
Power the components and upload the code
As soon as the IR sensors detecting vehicles, the street lights will glow immediately
Similarly as soon as the IR sensors stops detecting the vehicle, the Street lights will turned off
The data regarding present status of the light can be updated in the remote server and can be retrieved for analysis

Software requirements:

Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
Thingspeak : Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online

Programming language: Arduino Programming (C++)
