IR Reflectance Sensor - QRE1113
We can get 702 units in Australia from SparkFun. If you order today, we can dispatch this stock between Dec 15, 2019 - Dec 17, 2019.
The QRE1113 is a small IR reflectance sensor. This sensor is often used in line following robots because, if it can sense if a surface is white or black.
There are four pins on the QRE1113 - two control the IR emitting LED while the other two are the collector and emitter of a phototransistor. The IR diode has a max forward current of 50mA and operates at 940nm.
