Introduction
Want to measure speed with an Arduino? A speed sensor helps calculate the velocity of moving objects using infrared or magnetic sensors. In this guide, we will walk you through the step-by-step process of building an Arduino-based speed sensor, including circuit connections, code, and applications.
What is a Speed Sensor?
A speed sensor is a device that detects the movement of an object and measures its velocity. It is commonly used in vehicles, industrial automation, and robotics. In this project, we use an IR sensor and Arduino to track speed.
Components Required
- Arduino Uno
- IR Sensor Module
- LCD Display (16x2)
- Resistors & Capacitors
- Breadboard & Jumper Wires
Circuit Diagram & Working
The IR sensor detects when an object passes through it. By measuring the time taken between two points, we calculate the speed using the formula:
Speed = Distance / Time
Applications of Arduino Speed Sensors
- Automobile speed monitoring
- Industrial conveyor belt tracking
- Robotics & automation
- Sports performance analysis
Building an Arduino-based speed sensor is simple and effective. With a few components and code modifications, you can customize it for different applications. Try this project and share your results.
