Pololu QTR-MD-08A Reflectance Sensor Array: 8-Channel, 8mm Pitch, Analog Output

The QTR-MD-08A Reflectance Sensor Array is an 8-channel device with an 8mm pitch and analog output. It measures 61.0mm x 20.0mm in size and operates optimally within a 5mm range. Its maximum LED current is 30mA and the board can handle up to 125mA. The QTR-MD-08A is equipped with an array of IR LED/phototransistor pairs, making it an excellent tool for accurately identifying changes in reflectance, such as line detection. It operates within a voltage range of 2.9V to 5.5V and has a dimmable brightness control that is independent of the supply voltage.Generally, the closer the object, the higher the contrast between light and dark readings. However, the QTR-MD-08A can typically detect high-reflectance objects up to around 40mm away. This version of the sensor array features the traditional-style QTR sensors without lenses, offering a straightforward and effective solution for various applications.Whether you're a robotics enthusiast creating a line-following robot or a professional engineer working on a complex automation project, the QTR-MD-08A Reflectance Sensor Array could be the perfect component for your needs. Its unique properties and high-performance capabilities make it a reliable choice for a wide range of applications.
