QTR-HD-25RC Reflectance Sensor Array: 25-Channel, 4mm Pitch, RC Output



Description

The QTR-HD-25RC Reflectance Sensor Array is a high-quality product from Pololu, known for its precision in identifying changes in reflectance, such as line detection. It consists of 25 IR LED/phototransistor pairs, with a pitch of 4mm between each sensor. The size of the board is 101.0mm x 16.5mm, making it compact and suitable for various applications. The product operates from 2.9V to 5.5V, and it has a maximum current output of 30mA for the LED and 405mA for the board. The sensor array also offers a unique feature of dimmable brightness control, which is independent of the supply voltage. It provides separate controls for the odd and even emitters.

The QTR-HD-25RC Reflectance Sensor Array is particularly useful for applications that require precise detection of changes in reflectance. For instance, it can be used in robotics for line following, object detection, and navigation. With an optimal range of 5mm, it ensures high-contrast readings for objects that are close. However, it is also capable of detecting high-reflectance objects at distances up to 50mm. This makes it a versatile tool for various reflectance detection applications.

One of the unique properties of this sensor array is its ability to control the brightness independently of the supply voltage. This allows for more flexibility and precision in adjusting the brightness to suit specific requirements. Additionally, it offers separate controls for the odd and even emitters, providing more control and customization options. The traditional-style QTR sensors without lenses are a characteristic feature of this version, offering a reliable and effective solution for reflectance detection.

Overall, the QTR-HD-25RC Reflectance Sensor Array stands out for its precision, versatility, and unique features. It is a testament to Pololu's commitment to providing high-quality, innovative solutions for a variety of applications.
