This product is known as IR, IR Sensor, LM393, Counter, Photoelectric, Correlation, Correlation Sensor Module,Count Slot Sensor Module, Correlation Photoelectric Infrared Count Slot Sensor Module 15 mm.

It works as

1. The OUT pin is a low level when there is no object between the photoelectric sensor, and the red LED is lit.
2. The OUT pin is a high level when there is an object between the photoelectric sensor, and the green LED is not bright.
3. The OUT port can be connected to MCU directly, Than MCU can calculate how many circles the smaller car has run per unit
