Line Tracker IR Sensor Module

Description

• 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
