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, the output format: digital switching output (0 and 1)

7, a fixed bolt holes for easy installation

8 small plates PCB size: 3.2cm x 1.4cm

9, using a wide voltage LM393 comparator

Module functions is introduced: 

TCRT5000 sensor of infrared emission diode constantly launch infrared, the infrared ray is emitted when the intensity of reflected back has not been reflected or but is not big enough, the light activated triode has been in the off state, the output end of the module at this time for the high level, indicating diode has been put out state; Detected objects appear within the scope of testing, infrared light is reflected back and strength is enough big, light activated triode saturation, at this time the output of the module for the low level, instructs the diode lights.

Package includes:

1 x  TCRT5000 Infrared Reflective Sensor Module
