The QRD1114 is an infrared reflective optical sensor with a phototransistor output. It typically comes in a 4-pin package. Here's a concise breakdown of its pin configuration and function:
1. Pin 1 (Anode): Connects to the positive side of the power supply and is used to power the infrared LED.

2. Pin 2 (Cathode): Connects to the negative side of the power supply, completing the LED circuit.
3. Pin 3 (Collector): The collector of the phototransistor, which is used to detect the reflected infrared light.
4. Pin 4 (Emitter): The emitter of the phototransistor, typically connected to ground or a reference voltage.
Functionally, the QRD1114 emits infrared light from its LED, which is then reflected off nearby objects back to its phototransistor. The phototransistor's conductivity changes based on the amount of reflected infrared light it detects, allowing it to function as a proximity sensor or for object detection purposes.
