QTR-HD-02A Reflectance Sensor Array: 2-Channel, 4mm Pitch, Analog Output

Pololu brings you the QTR-HD-02A Reflectance Sensor Array, a compact and efficient solution for detecting changes in reflectance. This 2-channel sensor array, with a pitch of 4mm, is equipped with IR LED/phototransistor pairs that are perfect for tasks such as line detection. The product dimensions are 10.2mm x 20.0mm, making it compact and easy to integrate into your projects.

The sensor array operates from a voltage range of 2.9V to 5.5V, and it also features dimmable brightness control that is independent of the supply voltage. It consumes a maximum current of 32mA for the board and 30mA for the LED. The optimal range for this sensor array is 5mm, providing you with high precision in your tasks.

What sets the QTR-HD-02A Reflectance Sensor Array apart is its high contrast detection. The closer the object, the higher the contrast between light and dark readings. This makes it ideal for projects that require precision and accuracy. Moreover, it can detect high-reflectance objects up to approximately 30mm away. This version of the sensor array comes without lenses, staying true to the traditional-style QTR sensors.

Whether you're working on a robotics project or a complex automation task, this reflectance sensor array can be a game-changer. Its compact size, high precision, and efficient power consumption make it an excellent choice for a variety of applications. With the QTR-HD-02A Reflectance Sensor Array, you can take your project to the next level.
