Pololu QTR-MD-13A Reflectance Sensor Array: 13-Channel, 8mm Pitch, Analog Output

The QTR-MD-13A Reflectance Sensor Array is a 13-channel device with an 8mm pitch and analog output. Its dimensions are 101.0mm x 16.5mm. The device operates at a maximum current of 30mA for the LED and 220mA for the board, with an optimal range of 5mm. The QTR-MD-13A Reflectance Sensor Array is perfect for accurately detecting changes in reflectance, such as line detection. It functions optimally between 2.9V to 5.5V. Unique to this device is its dimmable brightness control, which operates independently of the supply voltage. It also offers separate controls for the odd and even emitters. As a general rule, the closer the object, the higher the contrast between light and dark readings. However, high-reflectance objects are typically detectable up to approximately 40mm. This model features the traditional-style QTR sensors without lenses, offering a straightforward and reliable solution for various applications.The QTR-MD-13A Reflectance Sensor Array from Pololu brings together precision, versatility, and ease of use, making it an essential tool for a wide range of projects and applications.
