Now a day's every system is automated in order to face new challenges. In the present days Automated systems have fewer manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. The project aims to design and develop an automatic vehicle speed detection system. The system uses two IR sensors placed at a fixed distance to measure the time taken by a vehicle to travel between them, and the speed is calculated accordingly. The calculated speed is displayed on a 16×2 LCD in km/h along with the speed status, such as Normal or High Speed. A buzzer is activated to provide an alert when the vehicle exceeds the preset speed limit. To accomplish this task, an Arduino Uno is programmed using Embedded C language to process sensor inputs, compute speed, control the display, and trigger alerts.      

The major features of this project are:

• IR sensor-based vehicle speed detection.
• Monitoring the vehicle speed and speed level on LCD.
• High Speed alerts using BUZZER.
• To achieve this task using Arduino UNO microcontroller.

      The major building blocks of this project are:  

1. Power Supply.
2. Arduino UNO.
3. TWO IR sensors.
4. LCD display.
5. Buzzer.

      Software’s used:

• Arduino IDE for compiling and dumping code into Microcontroller
• Express SCH for Circuit design.

      Regulated Power Supply:
