The slot type photoelectric sensor is composed of an infrared light emitting diode and an NPN phototransistor with a groove width of 5.9 mm. As long as the non-transparent object passes through the slot type, it can be triggered (used with our car code wheel) to output TTL low level. The Schmitt trigger is used to shake the pulse, which is very stable and can be used for measuring the speed of the car, measuring the distance and the like!
