QTR-1RC Reflectance Sensor
 
|
The QTR-1RC reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following applications. The output is designed to be measured by a digital I/O line.
