QTR-8RC Reflectance Sensor Array SF_Biometrics * [SEN54](https://wwwThis sensor module has 8 IR LED phototransistor pairs mounted on a 0. 375" pitch, making it a great detector for a line following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power savings options. Each sensor provides a separate digital I O measurable output . Note: The QTR 8RC reflectance sensor array requires digital I O lines to take readings. The
