The Okdo TelePort 3-channel line tracking sensor adopts the TCRT5000 infrared tube. Its working principle is to use different reflectivity of infrared light to colors, then convert the strength of the reflected signals into current signals. During the process of detection, black is active at HIGH level while white is active at LOW level. The detection height is 0-3 cm. Compatible with RJ11 6P6C OKdo TelePort Control boards and expansion shields
Detection range between 0-3 cm
Sensitivity can be adjusted with the three on-bard potentiometers
