Pololu QTRX-MD-02A Reflectance Sensor Array: 2-Channel, 8mm Pitch, Analog Output, Low Current

The QTRX-MD-02A Reflectance Sensor Array is a 2-Channel, 8mm Pitch, Analog Output, Low Current device. It features a pitch of 8mm x 2 sensors, a compact size of 13.0mm x 20.0mm, and an analog output. The maximum current for the LED is 3.5mA, while the board can handle up to 5mA. The optimal range for this sensor array is 10mm. The QTRX-MD-02A is equipped with an array of infrared LED/phototransistor pairs, making it highly effective for identifying changes in reflectance such as line detection. It can operate from a voltage range of 2.9V to 5.5V, offering the advantage of dimmable brightness control that is independent of the supply voltage.The closer the object to the sensor, the higher the contrast between light and dark readings. However, high-reflectance objects can generally be detected at distances up to 30mm. The QTRX-MD-02A is a high-performance, low-current sensor array that comes with lenses for enhanced performance.Reselling Sparkfun products, Pololu offers the QTRX-MD-02A Reflectance Sensor Array, a perfect solution for applications that require precise detection of changes in reflectance. Its compact size, low current requirement, and high-performance make it a versatile and reliable choice for various applications.
