Pololu QTR-HD-06A Reflectance Sensor Array: 6-Channel, 4mm Pitch, Analog Output

The QTR-HD-06A Reflectance Sensor Array is a 6-channel, 4mm pitch, analog output device. This compact unit, measuring just 25.0mm x 20.0mm, is designed for precise detection of changes in reflectance, such as line detection. It is capable of operating from 2.9V to 5.5V, with a maximum current of 30mA for the LED and 93mA for the board. Its optimal range is 5mm, but high-reflectance objects can generally be detected up to 40mm.The QTR-HD-06A Reflectance Sensor Array is equipped with an array of IR LED/phototransistor pairs. This makes it an excellent tool for applications that require precision and accuracy. Whether you're working on a robotics project or developing a system that relies on line detection, this sensor array can provide the reliable performance you need.One of the key benefits of this sensor array is its dimmable brightness control. This feature is independent of the supply voltage, offering flexibility and adaptability in various lighting conditions. Additionally, it has separate controls for the odd and even emitters, allowing for more precise control and adjustment.Despite its compact size, the QTR-HD-06A Reflectance Sensor Array does not compromise on detection range. High-reflectance objects can be detected up to 40mm away, making it a versatile tool for a wide range of applications. This version features the traditional-style QTR sensors without lenses, providing a straightforward, uncomplicated user experience.
