Pololu QTR-HD-11A Reflectance Sensor Array: 11-Channel, 4mm Pitch, Analog Output

The QTR-HD-11A Reflectance Sensor Array is a versatile and precise tool with 11 channels, a 4mm pitch, and an analog output. The sensor array measures 45.0mm x 20.0mm and operates optimally within a range of 5mm. It has a maximum LED current of 30mA and a board current of 185mA. The array operates from a voltage range of 2.9V to 5.5V. The QTR-HD-11A Reflectance Sensor Array is perfect for identifying changes in reflectance with precision, making it an ideal tool for tasks such as line detection. It offers dimmable brightness control that is independent of the supply voltage, and separate controls for the odd and even emitters.The closer the object, the higher the contrast between light and dark readings. However, high-reflectance objects are generally detectable up to around 40mm. This makes the QTR-HD-11A Reflectance Sensor Array a versatile tool for a variety of applications. This version features the traditional-style QTR sensors without lenses, offering a straightforward and uncomplicated user experience.With its unique properties and benefits, the QTR-HD-11A Reflectance Sensor Array is a reliable tool for those who require precise and accurate reflectance readings. Whether for professional or hobbyist use, this sensor array delivers exceptional performance and flexibility.
