QTR-HD-02RC Reflectance Sensor Array: 2-Channel, 4mm Pitch, RC Output

The QTR-HD-02RC Reflectance Sensor Array is a compact, highly precise device with a 2-channel, 4mm pitch, and RC output. It measures only 10.2mm x 20.0mm in size, making it ideal for projects that require a small footprint. The sensor array operates between 2.9V to 5.5V, with a maximum current for the LED and board at 30mA and 32mA respectively. It features an optimal range of 5mm.

The QTR-HD-02RC is equipped with an array of IR LED/phototransistor pairs. This makes it excellent for identifying changes in reflectance with high precision, such as line detection. The sensor array offers dimmable brightness control, which is independent of the supply voltage. This allows for greater flexibility and adaptability in various lighting conditions.

With the QTR-HD-02RC, the closer the object, the higher the contrast between light and dark readings. However, it's worth noting that high-reflectance objects are generally detectable up to around 30mm. This makes the sensor array versatile and suitable for a wide range of applications. This particular version features traditional-style QTR sensors without lenses, providing a clear, unobstructed view for precise detection.

Whether you're creating a line-following robot, an automated sorting system, or any project that requires precise detection of changes in reflectance, the QTR-HD-02RC Reflectance Sensor Array is a reliable and efficient choice. With its small size, high precision, and flexible voltage operation, it's a versatile tool that can elevate your project to new heights.
