Pololu QTRX-HD-02A Reflectance Sensor Array: 2-Channel, 4mm Pitch, Analog Output, Low Current

The QTRX-HD-02A Reflectance Sensor Array is a 2-channel, 4mm pitch device with an analog output and low current. It is a compact sensor with dimensions of 10.2mm x 20.0mm. The array has a maximum current of 3.5mA for the LED and 5mA for the board. The optimal range for this device is 10mm.Equipped with an array of IR LED/phototransistor pairs, the QTRX-HD-02A Reflectance Sensor Array is excellent for accurately identifying changes in reflectance, such as line detection. The device can operate from 2.9V to 5.5V and provides adjustable brightness control, independent of the supply voltage.The QTRX-HD-02A Reflectance Sensor Array offers superior performance in detecting high-reflectance objects, generally detectable up to around 30mm. The closer the object, the higher the contrast between light and dark readings. This version of the sensor array features high-performance, low-current QTRX sensors with lenses, enhancing its ability to accurately detect and measure reflectance.With its compact size, low current, and high-performance sensors, the QTRX-HD-02A Reflectance Sensor Array is a versatile and reliable tool for a variety of applications. It's ideal for robotics, automation, and other projects that require precise detection and measurement of changes in reflectance.
