QTR-HD-15A Reflectance Sensor Array: 15-Channel, 4mm Pitch, Analog Output

The QTR-HD-15A Reflectance Sensor Array is a 15-Channel, 4mm Pitch, Analog Output device that offers precision in identifying changes in reflectance, such as line detection. The device's size measures 61.0mm x 20.0mm, and it operates optimally within a range of 5mm. It functions with a maximum current of 30mA for the LED and 250mA for the board. The array operates from 2.9V to 5.5V, providing dimmable brightness control independent of the supply voltage. It also features separate controls for the odd and even emitters.

The QTR-HD-15A Reflectance Sensor Array is perfect for applications requiring precise detection of changes in reflectance. For instance, it can be used in robotics for line detection or object recognition. The closer the object, the higher the contrast between light and dark readings. However, high-reflectance objects can generally be detected up to around 50mm.

One of the key benefits of the QTR-HD-15A Reflectance Sensor Array is its ability to control brightness independently of the supply voltage. This allows for greater flexibility and precision in various lighting conditions. Additionally, the separate controls for odd and even emitters enable more refined control over the sensor's performance.

This version of the QTR-HD-15A Reflectance Sensor Array features the traditional-style QTR sensors without lenses, providing a more straightforward, uncomplicated user experience. It's a reliable choice for those seeking a robust and precise reflectance sensor array.
