  • Electricity meter pulse data sampling.
  • Fax machine. shredder paper detection.
  • Obstacle detection.
  • Black and white line detection.


Module features:

  • Using infrared reflection sensors TCRT5000.
  • Test reflection distance: 1mm to 25mm.
  • Clean and 3. the comparator output. signal waveform. driving ability is strong. for more than 15 ma.
  • With many adjustable precision potentiometer to adjust sensitivity.
  • The working voltage of 3.3V to 5V.
  • Output form: digital switch output (0 and 1).
  • Has a fixed bolt hole. convenient installation.
  • Small board PCB size: 3.2cm x 1.4cm.
  • The LM393. use of wide voltage comparator.
  • Size: 3.1 x 1.3cm (approx).


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.
