Description QRD1114 Reflective Object Sensor

The QRD1114 is a powerful object detection sensor. This sensor uses infrared light to detect the presence of objects. It contains an infrared emitter and an NPN photodarlington. These are placed side by side in a compact, black housing. The QRD1114 works efficiently by emitting light. If an object reflects this light, the sensor captures it. This technique is useful in many applications, such as robots and copiers.

The operation is simple but effective. Light from the infrared emitter reflects from a surface. The photodarlington detects this. The more light that comes back, the closer the object is to the sensor. This principle makes the QRD1114 reliable for object detection. The sensor works best with a supply voltage of 5V DC. Its small dimensions (4.39 x 6.1 x 4.65mm) make it ideal for use in confined spaces. The QRD1114 functions well at temperatures from -40 to 85°C. This makes it suitable for various environments.
