Description
This Infrared Slotted Speed Sensor Module is perfect for adding precise speed measurement and motion detection to your Arduino, Raspberry Pi, or other microcontroller projects.
Powered by 3.3V or 5V, it uses an LM393 comparator to provide a clean digital output signal when motion is detected through a slotted disc.
Ideal for projects requiring motion feedback, rotation counting, or speed sensing.
