Arduino RPM Sensor for Measuring Rotational Speed | Infrared Speed Sensor Module

The Arduino RPM Sensor Module is a simple and accurate solution for measuring rotational speed (RPM) of motors, fans, and other rotating parts. It uses an infrared (IR) emitter and receiver pair to detect reflected light from a white/black pattern or reflective tape placed on a rotating surface.

When the reflective mark passes in front of the sensor, it generates a pulse signal that can be read by an Arduino, ESP32, or any microcontroller to calculate RPM or speed. This makes it ideal for motor speed measurement, automation systems, and robotics.

The module features a digital output, onboard signal indicator LED, and sensitivity adjustment potentiometer, making it both easy and precise to use.

Features:

1. Measures rotational speed (RPM) using IR reflection
2. Non-contact sensing for longer life and reliability
3. Adjustable sensitivity via onboard potentiometer
4. Digital output (High/Low) compatible with Arduino and ESP32
5. Onboard power and signal indicator LEDs
6. Compact and easy to install on mechanical setups
7. Ideal for motor speed, fan RPM, and automation systems
