Careful examination of the datasheet is crucial for selecting appropriate external components, such as resistors, and designing the sensor’s interface with a microcontroller or other control circuitry.
The Qrd1114 sensor utilizes an infrared (IR) LED and a phototransistor. The IR LED emits infrared light, and the phototransistor detects the reflected light. When an object is close to the sensor, more IR light is reflected back onto the phototransistor, causing it to conduct more current. This change in current can be measured and used to determine the presence of an object. Key specifications to watch for in the Qrd1114 Datasheet include:
- Forward voltage of the IR LED
- Collector-emitter voltage of the phototransistor
- Typical and maximum operating currents
- Sensing distance
