TCRT5000 Infrared Reflective Sensor 5V IR Photoelectric Switch Barrier Line Track Module For Arduino Diode Triode Board

TCRT5000 Chip:

 
Works TCRT5000 sensors and infrared sensors generally as a pass for a sense .
TCRT5000 has an infrared emitter and an infrared receiver tube.
When the infrared emission of the reflected signal is received by the receiver tube, receiving tube resistance will change 
    the circuit is generally in the form of voltage change reflected, and after the ADC conversion circuit such as plastic or LM324 output result obtained after the treatment.
since the resistance change take on the intensity of the infrared signal received by the receiving tube, often show the reflecting surface .
    the color and the reflective surface of the distance between the receiver tube hardware reference schematics two aspects as follows:

Black TCRT5000 Product Usage:

1, power meter pulse data sampling

2, fax machine paper machine paper detection

3, barrier detection

4, black and white line detection

product description:

1, using TCRT5000 infrared reflection sensor

2, detection of reflection distance: 1mm ~ 25mm applicable

3, the working voltage: 5V

4, the output form: digital signals (0 and 1)

5, with a fixed bolt hole, easy to install

6, small board PCB size: 3.5cm x 1cm

7, single weight: 4.5g

Features:

TCRT5000 sensor infrared emission diodes continue to emit infrared, when the emitted infrared rays are not reflected back or reflected back but the intensity is not big enough, the infrared receiver tube has been in the off state, then the module output is low, indicating The diode is in the extinguished state; when the object is detected within the detection range, the infrared rays are reflected back and the intensity is large enough, the infrared receiver is saturated, and the output of the module is high, indicating that the diode is lit.

Wiring:

1, VCC: then the power supply positive (5V)

2, GND: Connect the power supply negative

3, OUT: high / low switching signal (digital signals 0 and 1)
