This module is a digital line tracking sensor you can use with Arduino to make a better line follower robot that can sense 8 way of black and white lines. The more ways it can sense, the more resolution the sensor gets!

This module works based on the reflection of infrared light. When following a line, the black line must therefore be able to absorb infrared light (approximately 950nm wavelength). The outputs of the sensors are high when enough light is reflected back.


  • Voltage : 3.3 – 5V
  • Output Type : Digital
  • Two 3mm mounting holes
  • 8-way reflective optical sensors
  • Dimensions : 17 x 67 x 2 mm



GNDGroundConnect to GND of system
IRInfrared enableConnect to 3.3V or 5V of system (digital pin also will do)
D1 – D8Sensor output pinsConnect to any digital pins
VCCPower sourceConnect to 3.3V or 5V of system


Note : To run the module at 3.3V, connect the solder pads in the bottom left corner to brighten the IR LEDs.
