Pololu QTRX-HD-07RC Reflectance Sensor Array: 7-Channel, 4mm Pitch, RC Output, Low Current

The Pololu QTRX-HD-07RC Reflectance Sensor Array is a compact and efficient 7-channel device with a 4mm pitch and RC output. The array measures 29.0mm by 20.0mm and operates at a maximum current of 3.5mA for the LED and 17mA for the board. It is designed to work optimally within a range of 10mm.The QTRX-HD-07RC Reflectance Sensor Array is equipped with an array of IR LED/phototransistor pairs, making it an excellent choice for tasks that require precise identification of changes in reflectance, such as line detection. It operates within a voltage range of 2.9V to 5.5V and features dimmable brightness control that is independent of the supply voltage. This allows for separate controls for the odd and even emitters.One of the key benefits of this sensor array is its high contrast between light and dark readings when the object is closer. However, it also has the capability to detect high-reflectance objects at a distance of up to 40mm. The QTRX-HD-07RC Reflectance Sensor Array stands out for its high-performance, low-current QTRX sensors with lenses, providing enhanced accuracy and efficiency in reflectance detection.The QTRX-HD-07RC Reflectance Sensor Array is a reliable and versatile tool that can be integrated into various applications. Whether it's for robotics, automation systems, or other projects that require precise detection and differentiation of reflective surfaces, this sensor array delivers exceptional performance and precision.
