QTR-MD-08RC Reflectance Sensor Array: 8-Channel, 8mm Pitch, RC Output

The Pololu QTR-MD-08RC Reflectance Sensor Array is an impressive 8-channel device with an 8mm pitch and RC output. With dimensions of 61.0 x 20.0mm, this sensor array is compact and easy to integrate into various applications. The device operates efficiently, with a maximum LED current of 30mA and a board current of 125mA. The optimal range for this sensor array is 5mm.The QTR-MD-08RC is equipped with an array of IR LED/phototransistor pairs that are highly effective in identifying changes in reflectance, making it excellent for tasks such as line detection. The device operates from a supply voltage of 2.9V to 5.5V and features dimmable brightness control that is independent of the supply voltage.The closer the object is to the sensor, the higher the contrast between light and dark readings. However, the device can generally detect 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 simple and straightforward solution for various sensing needs.By choosing the Pololu QTR-MD-08RC Reflectance Sensor Array, you're opting for a reliable, precise, and high-performing device that can significantly enhance your project's capabilities. Whether you're working on a line-following robot or a system that requires precise object detection, this sensor array is a great choice.
