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 in the off state. At this time, the output end of the module is high level, and the indicator diode is always in the off state; when the detected object appears in the detection range, the infrared rays are reflected back and the intensity is strong enough, the infrared receiving tube is saturated, and the output end of the module is low level, and the indicator 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 can generally be left unconnected)
