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. Breakout boards with analog and digital outputs are also available. Features: * Phototransistor output * No contact surface sensing * Miniature package * SMT gull wing leads Documents: * Datasheet https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2009-11-22 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-11-25 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-11-28 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-11-29 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-12-09 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-12-13 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2016-12-26 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2017-01-10 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2017-11-24 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2017-11-28 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2018-05-05 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2018-11-21 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2018-11-27 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2022-02-21 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2025-04-12 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2025-04-14 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2025-04-16 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2025-06-04 https://elecena.pl/product/962151/ir-reflectance-sensor-qre1113 2025-06-07
