OV2640 2 Megapixel Camera Module Previous 
LM393 Infrared Optocoupler Speed Sensor Module is a microcontroller-compatible motor speed sensor module for pulse counting, motor speed detection, and position limit applications. It uses an infrared optocoupler sensor with an infrared LED and phototransistor to detect when the optical path is interrupted. The LM393 comparator converts the sensor change into a digital output signal. The module includes signal output indication and provides a single signal output. It is designed for use in electronics and robotics projects where optical pulse detection is required.
