IR Line Tracking Module

Description 

This is a line detection sensor module based on infrared (IR) reflection and it is super easy to use. The sensor has been mounted at the bottom of the module, perfect for mobile robot line detection. It comes with an onboard potentiometer to adjust the sensitivity. The output is digital signal so it is easy to interface with any microcontroller such as Arduino UNO, ESP32, or Raspberry Pi Pico.

Features
  • 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
