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).

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).

QTR-8RC Reflectance IR Sensor Array. This 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.

The QTR-8RC Line Following Reflectance IR Sensor Array is a powerful and efficient tool designed for line following applications in robotics. This sensor array consists of 8 infrared (IR) emitter-detector pairs arranged in a row, which can detect the reflectance of surfaces.

Infrared Reflectance Sensor Array: fail-safe sensitivity, maximum energy savings This Infrared Reflectance Sensor Array’s two main qualities? First, its acuity, which is enhanced by its digital I/O-measurable output (more sensitive than an analogue output with voltage divider bridge).

2019年3月18日 · I’ll show you how to program a QTR sensor array, let’s get started. As far as parts go, assuming you’ve already built the robot we just need the following items. As always, there is a video you can watch if you’re more into that sort of thing. This video covers attaching the sensor and testing the line array.

Autonomous Line Follower Robot Using QTR-8A (Reflectance Sensor Array) This repository contains the code for a line-following robot implemented on an Arduino platform. The robot utilizes infrared (IR) sensors to detect the position of a line on the ground and adjusts its movements accordingly to follow the line.
