2. Detects reflection distance: 1mm~25mm applicable

3. Comparator output, clean signal, good waveform, strong driving capability, exceeding 15mA.

4. Equipped with a potentiometer for sensitivity adjustment

5. Operating voltage 3.3V-5V

6. Output form: Digital switch quantity output (0 and 1)

7. Fixed bolt holes for convenient installation

8. Small board PCB size: 3.2cm x 1.4cm

9. Uses a wide-voltage LM393 comparator

Functional Overview:

The infrared emitting diode of the TCRT5000 sensor continuously emits infrared light. When the emitted infrared light is not

reflected back or is reflected back but with insufficient intensity, the infrared receiver is in the off state, and the module's

output is at a high level, indicating that the diode is off. When the detected object appears within the detection range, the

reflected infrared light is sufficient to saturate the infrared receiver. At this point, the module's output is at a low level,

indicating that the diode is lit.

Wiring Method:

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 distances output different voltages, this pin can generally be left unconnected)
