IR SPEED SENSOR MODULE FOR ARDUINO ESP32

This is a versatile and easy-to-use IR (Infrared) speed sensor module, perfect for your next robotics or automation project. It’s built around a reliable LM393 comparator and features a slotted optical switch, also known as a photo-interrupter. Just slide an encoder disk (or any object) through the slot to break the IR beam, and the sensor will send a signal. It’s a piece of cake to get running. The module provides both a clean digital output (HIGH/LOW) and a raw analog output. With an onboard potentiometer, you can easily fine-tune the sensitivity for your specific needs. It’s ideal for measuring motor speed (RPM), counting rotations, or creating simple limit switches.
