Pololu QTRX-HD-03A Reflectance Sensor Array: 3-Channel, 4mm Pitch, Analog Output, Low Current

The QTRX-HD-03A Reflectance Sensor Array is a compact and efficient product, equipped with 3-channel, 4mm pitch sensors, and designed to provide accurate analog output. It measures 13.0 x 20.0mm in size and operates optimally within a range of 10mm. The sensor array requires a maximum current of 3.5mA for the LED and 9mA for the board. The QTRX-HD-03A Reflectance Sensor Array is ideal for detecting changes in reflectance with precision, making it perfect for tasks such as line detection. It operates effectively within a voltage range of 2.9V to 5.5V. The brightness can be easily adjusted, independent of the supply voltage, to suit your specific requirements.One of the unique features of this sensor array is its ability to provide higher contrast between light and dark readings when the object is closer. However, it can detect high-reflectance objects at a distance of up to 30mm. This version of the sensor array is equipped with high-performance, low-current QTRX sensors with lenses, enhancing its efficiency and reliability.Whether you're a hobbyist or a professional, the QTRX-HD-03A Reflectance Sensor Array is a versatile tool that can be used in a variety of applications. It's not only easy to use but also offers reliable performance, making it a valuable addition to your toolkit.
