The QTR-HD-31RC Reflectance Sensor Array is capable of offering dimmable brightness control that is independent of the supply voltage. It also provides separate controls for odd and even emitters. The sensor array has a maximum current of 30mA for the LED and 495mA for the board. Its optimal range is 5mm, but it can generally detect high-reflectance objects out to around 50mm.
One of the key benefits of this sensor array is its precision in identifying changes in reflectance. This makes it an ideal tool for various applications that require accurate line detection. Moreover, its ability to control brightness independently of the supply voltage adds to its flexibility and adaptability in different operating conditions.
The unique feature of this version of the sensor array is that it features the traditional-style QTR sensors without lenses. This means it offers a raw, unfiltered and direct method of detecting changes in reflectance. This is particularly beneficial in applications where the highest level of accuracy and precision is required.
