QTR-HD-06RC Reflectance Sensor Array: 6-Channel, 4mm Pitch, RC Output

The QTR-HD-06RC Reflectance Sensor Array is an innovative product from Pololu, featuring 6 channels and a 4mm pitch with RC output. The sensor array measures 25.0mm x 20.0mm in size and is designed to identify changes in reflectance with precision, making it perfect for tasks like line detection. It operates optimally within a range of 5mm and can function efficiently with a power supply ranging from 2.9V to 5.5V.

The QTR-HD-06RC is equipped with IR LED/phototransistor pairs and offers dimmable brightness control that is independent of the supply voltage. This feature allows for separate controls for the odd and even emitters, enhancing the versatility of the sensor array. The maximum current for the LED and the board are 30mA and 93mA respectively.

One of the unique properties of the QTR-HD-06RC is its ability to detect high-reflectance objects up to around 40mm. This means that the closer the object, the higher the contrast between light and dark readings. This version of the sensor array comes with the traditional-style QTR sensors, but without lenses, providing a more straightforward and practical user experience.

In terms of usage, the QTR-HD-06RC Reflectance Sensor Array can be used in a variety of applications, from robotics to automated systems, where precise detection of changes in reflectance is required. With its unique features and robust performance, the QTR-HD-06RC is a reliable choice for those seeking a high-quality sensor array.
