QTR-HD-15RC Reflectance Sensor Array: 15-Channel, 4mm Pitch, RC Output

The QTR-HD-15RC Reflectance Sensor Array: 15-Channel, 4mm Pitch, RC Output is a top-notch product from Pololu. It features a 4mm pitch with 15 sensors, a size of 61.0mm x 20.0mm, RC (digital) output, a maximum LED current of 30mA, a maximum board current of 250mA, and an optimal range of 5mm.

The Reflectance Sensor Array is equipped with an array of IR LED/phototransistor pairs, making it an excellent choice for accurately identifying changes in reflectance, such as line detection. It operates within a voltage range of 2.9V to 5.5V. Furthermore, it offers the advantage of dimmable brightness control, which is independent of the supply voltage. It also provides separate control options for odd and even emitters.

The QTR-HD-15RC Reflectance Sensor Array is designed to enhance the contrast between light and dark readings when the object is closer. However, it can generally detect high-reflectance objects up to approximately 50mm. This version of the sensor array features the traditional QTR sensors without lenses, offering a classic and reliable design.

With its precise detection and versatile control options, the QTR-HD-15RC Reflectance Sensor Array is an ideal choice for robotics, automation, and other applications where accurate line or object detection is required. Its compact size and low power requirements make it a practical and efficient solution for a wide range of projects.
