Pololu QTR-MD-05RC Reflectance Sensor Array: 5-Channel, 8mm Pitch, RC Output

The QTR-MD-05RC Reflectance Sensor Array is a 5-channel, 8mm pitch, RC output device from Pololu. This compact unit measures 37.0mm x 20.0mm and offers digital output. It requires a maximum current of 30mA for the LED and 93mA for the board, and operates optimally within a range of 5mm. The QTR-MD-05RC is equipped with an array of IR LED/phototransistor pairs, making it ideal for accurately detecting changes in reflectance, such as in line detection applications. The device is operational within a voltage range of 2.9V to 5.5V and features adjustable brightness control that is independent of the supply voltage.The closer the object to the sensor, the greater the contrast between light and dark readings. However, objects with high reflectance can generally be detected at distances of up to 40mm. This particular model of the QTR series does not include lenses, which allows for a more traditional sensor experience.Whether you're developing a robotics project, creating an automated system, or working on a device that requires precise detection of changes in light, the QTR-MD-05RC Reflectance Sensor Array is a reliable and efficient solution. Its compact size, pitch precision, and adjustable brightness make it a versatile tool for a wide range of applications.
