Vehicle Speed Measurement System 

Overview:

The Vehicle Speed Measurement System is an innovative project designed to measure the speed of moving vehicles using an ultrasonic sensor and display the result on an LCD screen. The system is based on Arduino Uno, which processes the distance and time data to calculate vehicle speed in real time.

At the initial stage, the system displays a startup message “Vehicle Speed Measurement” on the LCD screen for a few seconds. After that, the ultrasonic sensor continuously measures the distance of approaching objects. When the object crosses two predefined detection points, the system records the time difference and calculates the speed accordingly. The measured distance and calculated speed are then displayed on the LCD display.

This system provides a low-cost and efficient solution for traffic monitoring and speed detection, helping to identify overspeeding vehicles without human intervention.

Key Features:

1. Real-Time Speed Measurement: Calculates vehicle speed using time difference between two points.

2. Distance Monitoring: Continuously measures object distance using an ultrasonic sensor.

3. LCD Display Output: Shows real-time distance and calculated speed.

4. Low-Cost Design: Uses simple and affordable components.

5. Automatic Operation: No human involvement required for measurement.

6. Traffic Monitoring Application: Useful for detecting overspeeding vehicles.

7. Alert System: Buzzer and LEDs indicate system status and detection.
