Module Function Introduction:

The infrared emitting diode of TCRT5000 sensor continuously emits infrared rays. When the emitted infrared rays are not reflected back or reflected back but the intensity is not strong enough, the phototransistor remains in the off state. At this time, the output terminal of the module is at a low level, indicating that the diode is always in the off state; When the detected object appears within the detection range, the infrared rays are reflected back and the intensity is strong enough, causing the photosensitive transistor to saturate. At this time, the output terminal of the module is at a high level, indicating that the diode is lit up.
