Features:

The infrared emitting diode of the TCRT5000 sensor continuously emits infrared rays. When the emitted infrared rays are not reflected back or are reflected back but the intensity is not strong enough, the infrared receiving tube is always off. At this time, the output terminal of the module is high level, indicating The diode is always extinguished; when the detected object appears within the detection range, the infrared ray is reflected back with sufficient intensity, and the infrared receiving tube is saturated. At this time, the output terminal of the module is low level, indicating that the diode is lit.
Wiring:

1. VCC: Connect to the positive pole of the power supply (3-5V)
2. GND: Connect to the negative pole of the power supply
3. DO: TTL switch signal output
4. AO: Analog signal output (different voltages are output at different distances, this pin generally does not need to be connected)
