6, the output form: digital switching output (0 and 1)
7, a fixing bolt hole, easy to install
8, the small PCB board size: 3.2cm x 1.4cm
9, the use of wide voltage comparator LM393
Features:
TCRT5000 infrared emitting diodes emit infrared sensors continuously, when infrared rays emitted is reflected or not reflected back but the strength is not large enough, the infrared receiver has been in the off state, then the output of the module is high, indicating diode remains off state; occurs when the detected object is within the detection range, infrared rays are reflected and sufficient strength, saturation infrared receiver, then the output terminal of the module is low, the indicator LED is illuminated.
Wiring:
1, VCC: the positive supply (3-5V)
2, GND: negative one
3, DO: TTL switching signal output
4, AO: analog signal output (different output voltages at different distances, this pin is not connected generally)
