8x IR Line Tracking Module

With this module you can follow a black line by using infrared light. 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). 

The outputs of the sensors are high when enough light is reflected back.

Specifications:

• Voltage: 3.3-5V*
• Has two 3mm mounting holes
• 8 Infrared sensors
• Dimensions (LxW): 17x67mm

Pinout:

• GND: Ground/min
• VCC: Input voltage
• IR: On/off signal IR LEDs
• D1-D8: Output IR sensors

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