8x IR Line Tracking Module - 40mm Range

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.
