QTR-HD-11RC Reflectance Sensor Array: 11-Channel, 4mm Pitch, RC Output

The Pololu QTR-HD-11RC Reflectance Sensor Array is an 11-channel, 4mm pitch, RC output device. It is a compact assembly, measuring just 45.0mm x 20.0mm. This sensor array operates with a maximum current of 30mA for the LED and 185mA for the board, with an optimal range of 5mm.

The QTR-HD-11RC Reflectance Sensor Array is ideal for accurately detecting changes in reflectance, making it perfect for tasks such as line detection. It operates within a voltage range of 2.9V to 5.5V. The sensor array features dimmable brightness control that is independent of the supply voltage, as well as separate controls for the odd and even emitters.

The closer the object is to the sensor, the higher the contrast between light and dark readings. However, it is capable of detecting high-reflectance objects at a distance of up to 40mm. This version of the sensor array features the traditional-style QTR sensors without lenses, offering a straightforward, reliable solution to various sensing needs.

The QTR-HD-11RC Reflectance Sensor Array is a versatile tool that can serve a wide range of applications. Its ability to identify changes in reflectance with precision makes it an invaluable component in robotics, automation, and other tech-driven projects. Its compact size, along with its functional capabilities, make it a practical choice for projects where space is a premium.
