The QTR-8A reflectance sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals of 0.375" (9.525 mm). The Pololu QTR-8A and QTR-8RC reflectance sensor arrays are intended as line sensors, but they can be used as a general-purpose proximity or reflectance sensors. Each module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals of 0.375" (9.525 mm).

The QTR-8RC reflectance sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals of 0.375" (9.525 mm). Measures only 2.95" x 0.5" x 0.125" and weighs 3.09 grams. The Pololu QTR-8A Reflectance Sensor Array 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.

Ask a Question QTR-8A has been added to your Personal Library Open related page by Fomo.com Download schematic symbols, PCB footprints, pinout & datasheets for the QTR-8A by Pololu. Pololu offered, until recently two different eight sensor arrays, the QTR-8RC and the QTR-8A. The RC array uses an RC circuit and capacitor decay time to determine a reflectance amount whereas the A array uses a voltage divider to determine a reflectance amount. Within the past year pololu has released newer QTR-HD and QTR-MD sensors in all.
