Pololu QTRX-HD-25A Reflectance Sensor Array: 25-Channel, 4mm Pitch, Analog Output, Low Current
Detects reflectance changes with precision
Operates efficiently at 2.9 V to 5 V
Allows dimmable brightness control
Detects objects up to 50 mm away
Weighs only 6 grams for light applications
The Pololu QTRX-HD-25A Reflectance Sensor Array: 25-Channel, 4mm Pitch, Analog Output, Low Current is an advanced sensor array designed for precise detection of reflectance changes, such as those encountered in line detection applications. This sophisticated device comprises 25 IR LED/phototransistor pairs, each spaced at a 4 mm pitch, allowing for detailed and accurate readings. The array operates efficiently within a voltage range of 2.9 V to 5 V, providing flexibility in various electronic setups.
The sensor array is equipped with high-performance, low-current QTRX sensors that include lenses, enhancing their sensitivity and accuracy. The device features dimmable brightness control, which is independent of the supply voltage, and allows for separate adjustments of the odd and even emitters. This feature ensures optimal performance and adaptability to different environmental conditions.
The array is capable of detecting high-reflectance objects at distances up to approximately 50 mm, with optimal sensing occurring at around 10 mm. The output is provided in the form of analog voltages, ranging from 0 V to the supply voltage, facilitating easy integration with various analog input systems. The lightweight design, weighing only 6 grams, makes it suitable for applications where weight is a critical factor.
