The QRE1113 module is a breakout board for the QRE1113 reflective optical sensor, which combines an infrared LED emitter and a phototransistor detector. The sensing principle relies on measuring the discharge time of an onboard 10nF capacitor through the phototransistor. When IR light reflects off a bright surface, the phototransistor conducts more, discharging the capacitor faster, resulting in a shorter digital pulse width. This timing-based digital output provides a reliable method for distinguishing surface reflectivity without analog signal conditioning.
Designed for embedded electronics and robotics, the module includes all necessary passive components, simplifying interfacing with digital I/O pins on microcontrollers. Its compact form factor and single mounting hole facilitate secure installation in mobile platforms and automated systems where precise optical detection is required.
