- Optimizes sensor detection up to 40 mm
- Integrates seamlessly with digital I/O systems
The Pololu QTRX-MD-13RC Reflectance Sensor Array: 13-Channel, 8mm Pitch, RC Output, Low Current is an advanced sensor array designed for precise detection of reflectance changes, such as those encountered in line detection applications. It comprises 13 IR LED/phototransistor pairs, each spaced at an 8 mm pitch, allowing for detailed and accurate readings. The array operates efficiently within a voltage range of 2.9 V to 5 V, featuring dimmable brightness control that functions independently of the supply voltage. This control extends to separate management of the odd and even emitters, enhancing the versatility of the device.
The sensor array is equipped with high-performance, low-current QTRX sensors that include lenses, optimizing their ability to detect high-reflectance objects up to approximately 40 mm away. The closer the object, the more pronounced the contrast between light and dark readings, facilitating precise detection. The output is formatted as digital I/O-compatible signals, which can be read in parallel as timed high pulses, ensuring seamless integration with various systems.
Note: Ensure proper handling to avoid damage to the sensors or circuitry.
