Optical Detector / Phototransistor - QRD1114

The Sparkfun Optical Detector / Phototransistor - QRD1114 is a sensor that utilizes an infrared emitted diode in conjunction with an infrared phototransistor. This combination allows the device to detect reflected infrared signals. The QRD1114 is particularly adept at sensing transitions from black to white and can also be used to detect nearby objects within a range of 0.5 to 1 cm.

The QRD1114 sensor is an invaluable tool for a variety of applications. It can be used in robotics for line following or object detection, in security systems for intrusion detection, or in automation systems for object sensing. The sensor's ability to detect black-to-white transitions also makes it useful in applications such as barcode readers or printers.

The QRD1114 stands out for its simplicity and effectiveness. Its compact size allows it to be easily integrated into a variety of systems. The sensor operates using infrared signals, which means it is not affected by ambient light conditions, making it reliable in a wide range of environments.
