The QRD1114 sensor operates based on the principle of infrared reflection. It consists of an infrared LED emitter and a phototransistor receiver placed side by side within the sensor module. The infrared LED emits a beam of infrared light toward the target surface, while the phototransistor receives and measures the intensity of the reflected infrared light.
When an object is present within the sensor’s viewing range, the infrared light emitted by the LED reflects off the object’s surface and is detected by the phototransistor. The phototransistor then generates an electrical signal proportional to the intensity of the reflected light, allowing for distance measurement or object detection.
