Photo Interrupter Sensor, Robot Speed Measuring Module

Photo Interrupter Sensor, Robot Speed Measuring Module

Photo Interrupter Sensor is a light occlusion interrupt sensor, which is often used in smart car speed measurement.

Principle: This product adopts a WYC-H206 slot photoelectric sensor, one end is an infrared transmitting tube, and the other end is an infrared receiving. When there is a block, the infrared receiving end cannot receive infrared and outputs a high level, which is triggered by inverting Schmitt. The device becomes low-level output, and the signal lamp is on at the same time. The use of the Schmitt trigger makes the output signal more stable, with good waveform and no jitter.
