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

The QTRX-HD-02RC Reflectance Sensor Array is a compact and efficient device featuring a 2-channel, 4mm pitch, RC output, and low current. With dimensions of 10.2mm x 20.0mm, this sensor array operates optimally within a range of 10mm. Its digital RC output is powered by a maximum current of 5mA for the board and 3.5mA for the LED. The QTRX-HD-02RC Reflectance Sensor Array is an excellent choice for applications that require precise identification of reflectance changes, such as line detection. It operates smoothly within a voltage range of 2.9V to 5.5V. Plus, it offers the advantage of dimmable brightness control that remains independent of the supply voltage. One of the unique properties of this sensor array is the high contrast it provides between light and dark readings, especially when the object is closer. However, it is also capable of detecting high-reflectance objects at a distance of up to 30mm. This flexibility in detection range makes it a versatile tool for various applications.The QTRX-HD-02RC Reflectance Sensor Array stands out from other sensor arrays due to its high-performance, low-current QTRX sensors equipped with lenses. The inclusion of lenses enhances the performance of the sensors, ensuring accurate and reliable readings at all times. This makes it a reliable choice for projects that demand precision and consistency.
