Vehicle-Activated Smart Highway Lights

Description:

The “Vehicle-Activated Smart Highway Lights” is an innovative working model for students that demonstrates how automated lighting systems can improve energy efficiency on highways. This project simulates a smart lighting system that turns on only when a vehicle is detected, reducing unnecessary energy consumption while ensuring road safety.

The model is built on a 40 × 50 cm Foam Board or Sun Board base, representing a highway equipped with an intelligent lighting system. The system operates as follows:

Working Mechanism:

• Vehicle Detection via IR Modules:
  • IR sensors are placed along the highway to detect moving vehicles.
  • When a vehicle passes, the sensor sends a signal to the Arduino Uno microcontroller.
• Arduino Uno Microcontroller & LED Control:
  • The Arduino processes the input from the IR sensors and turns on the LED highway lights.
  • The lights remain on for a set duration and then turn off automatically to conserve power.
• Circuit Components & Power Regulation:
  • BC547 Transistors & Resistors help regulate current and control LED switching.
  • Jumper Wires & Straws provide structural and electrical support for the lighting setup.

Applications & Benefits:

• Reduces Energy Wastage by activating lights only when vehicles are present.
• Improves Road Safety by ensuring well-lit highways at night.
• Ideal for Smart Cities & Highways where energy-efficient infrastructure is required.
• Provides Hands-on Learning in sensor-based automation, Arduino programming, and smart energy solutions.
