TCRT5000 Infrared Reflective Sensor Module

This IR reflective sensor utilizes a TCRT5000 to detect color and distance. It emits IR and then detects if it receives the echo. This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black.
The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an on-board potentiometer to adjust the sensitivity.
The infrared diode will emmitting the infrared continutelly when the module connect to the power, when the emitted infrared light has not been reflected or the strength is not big enough,the triode will in the off state, at this time, D0 output logic LOW and the signal indicate LED off.

Features:

1. Using infrared reflective sensor TCRT5000
2. Detecting the reflected distance: 1mm ~ 25mm applicable
3. The comparator output signal clean, good waveform driving ability more than 15mA.
4. With multi-turn precision potentiometer adjustable sensitivity adjustment
5. The working voltage of 3.3V-5V
6. Output format: digital switching output (0 and 1)
7. Size: 3.2cm x 1.4cm
8. Using a wide voltage LM393 comparator

Application:

TCRT5000 sensors continuously emit 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.
1. Meter pulse data sampling
