TCRT5000 Infrared Reflective Sensor IR Photoelectric Switch Barrier Line Obstacle Avoidance Module Tracing Sensor Tracing Module 3.3-5Vfor Arduino Smart Car Robot
SIZE：
Length:0.55inch/14mm
Width: 1.22inch/31mm
Height:0.24inch/6mm
Wiring method:

VCC: Connect to the positive pole of the power supply (3-5V)
GND: Connect to the negative pole of the power supply
DO: TTL switch signal output
AO: Analog signal output (different voltages are output at different distances, this pin generally does not need to be connected)
Features:
Using TCRT5000 infrared reflection sensor
Detection reflection distance: 1mm~25mm applicable
Comparator output, clean signal, good waveform, strong driving ability, exceeding 15mA.
Distribution potentiometer to adjust sensitivity
Working voltage:3.3V-5V
Output Form: digital switching output (0 and 1)
Equipped with fixing bolt holes youjianeasy installation
Use wide voltage LM393 comparator
Working Current: 15mA
TCRT5000 sensors continuously emit infrared infrared emitting diodes
infrared rays emitted when not being reflected back or reflected back but the strength is not big enough,
the phototransistor has been in a shutdown state, then the output modules is high
indicating diode remains off state
when the object appeared to be detected within the detection range of the infrared is reflected back and the intensity is large enough, the phototransistor saturated
then the output of the module is low, indicating the diode is lit.
Place of Application:
⚪Meter Pulse Data Sampling
⚪Fax Paper Shredders Detection
⚪Obstacle Detection
⚪Black and white line detection
