Vehicle based Intensity controlled Street lighting System

One of the biggest problem the world facing now is Wastage of Power. Generally, in almost all the countries, you can see that whether there is vehicle present or not, the street will glow continuously for the entire night. Now imagine that there is a system where whenever the vehicle comes near the street light that street glows with full intensity and as soon as the vehicle move from that area the streetlight will be glow with very less intensity. Through this project, you are going to build a Power Efficient Street Lighting system.

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 high (It will glow with full intensity). Similarly whenever the IR sensors don’t detect the vehicle, immediately the Streetlight will be turned low (the street will glow at 10% intensity). We can make this happen by using the Triac circuit through you can flow of current to the street light. You can innovate the system to upload the data regarding Street light status into a remote server for further analysis.

Project Description:

1. 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.
2. 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
3. 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.
4. IR Sensors: The component we use to find whether there is any vehicle going on the road is called IR sensors (Infrared).
5. Triac Circuit: This Triac circuit will be used to reduce the voltage supplied to the components connected to it.

Project Implementation:

1. Interface the Relay and IR sensors and Triac circuit with Arduino
2. Power the components and upload the code
3. As soon as the IR sensors detecting vehicles, the street lights will glow with its full intensity immediately
4. Similarly as soon as the IR sensors stops detecting the vehicle, the Street lights will Starts glowing at 10% intensity
5. The data regarding present status of the light can be updated in the remote server and can be retrieved for analysis

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
2. 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
