IR Line Tracking Module


  • Operating voltage: 3.3V or 5VDC
  • 4-pin interface which are: AO, DO, GND and VCC:
    • AO is an analog output pin, the analog voltage will be high when there is no obstacle or infrared reflection. The voltage will gradually decrease when the infrared receive it high.
    • DO is a digital output pin from the sensor module, please connect to any digital input on your microcontroller. Will output logic LOW when object is detection
    • GND is where you connect to your controller ground or 0V
    • VCC is the +ve supply, connect to either +3.3V or +5V
  • Two LED indicators:
    • Power indicator LED
    • Object detection indicator LED
  • Obstacle detection range: 5mm to 10mm from the sensor
  • Adjustable sensitivity with an onboard potentiometer, this translates to an adjustable detection range.
  • Compact makes it easy to assembly
  • Digital and analog output
  • Compatible with all types of microcontrollers
  • Dimension: 3.2cm x 1.4cm

Packing List:

  • 1 x IR Line Tracking Module
