QTRX-MD-01A Reflectance Sensor: 1-Channel, 7.5mm Wide, Analog Output, Low Current

The QTRX-MD-01A Reflectance Sensor from Pololu is a compact and efficient sensor designed for precise detection of changes in reflectance such as line detection. With a size of 7.5mm x 20.0mm, this sensor is equipped with a single IR LED/phototransistor pair. It operates within a voltage range of 2.9V to 5.5V and features an analog output. The sensor has a maximum LED current of 3.5mA and a maximum board current of 5mA. The optimal range for this sensor is 10mm.

The QTRX-MD-01A is an excellent choice for projects that require precise object detection. The sensor's ability to identify changes in reflectance makes it ideal for tasks such as line detection. The closer the object, the higher the contrast between light and dark readings. However, even high-reflectance objects can be detectable up to a distance of 30mm. This makes the sensor versatile and suitable for a wide range of applications.

One of the unique features of this sensor is its dimmable brightness control which is independent of the supply voltage. This allows for greater flexibility and precision in controlling the sensor's performance. Additionally, the sensor features a high-performance, low-current QTRX sensor with lenses. This ensures superior performance while keeping power consumption to a minimum.

Overall, the QTRX-MD-01A Reflectance Sensor is a compact, efficient, and versatile sensor that offers a range of features designed for optimal performance. Its precise detection capabilities, adjustable brightness control, and low power consumption make it a reliable choice for a variety of applications.
