Pololu QTR-MD-01A Reflectance Sensor: 1-Channel, 7.5mm Wide, Analog Output

The QTR-MD-01A Reflectance Sensor is a compact, single-channel device with a size of 7.5mm x 20.0mm. It has an analog output and is powered by an IR LED/phototransistor pair. With a maximum current of 30mA for the LED and 32mA for the board, it operates efficiently between 2.9V to 5.5V. The sensor is designed to identify changes in reflectance with precision, making it ideal for line detection tasks. The optimal range for this sensor is 5mm. The QTR-MD-01A Reflectance Sensor is an excellent choice for applications requiring precise detection of changes in reflectance. It's particularly effective in line detection, where it can accurately identify the contrast between light and dark readings. The sensor's output is not dependent on the supply voltage, and its brightness can be dimmed as per your requirements. This makes it a versatile tool for a wide range of projects.One of the unique features of this sensor is its ability to detect high-reflectance objects up to approximately 30mm away. This capability extends its usefulness beyond close-range tasks, opening up a broader range of potential applications. The sensor does not come with lenses, featuring a traditional-style QTR sensor design.With its compact size and efficient power consumption, the QTR-MD-01A Reflectance Sensor is a reliable and versatile addition to your toolkit. Whether you're working on a line detection project or need to identify changes in reflectance, this sensor offers a practical solution. Its unique features and capabilities make it a valuable component for a wide range of applications.
