QTRX-MD-03RC Reflectance Sensor Array: 3-Channel, 8mm Pitch, RC Output, Low Current

Pololu's QTRX-MD-03RC Reflectance Sensor Array is an innovative product that combines 3 IR LED/phototransistor pairs with an 8mm pitch. The compact size of 21.0 x 20.0mm is perfect for applications where space is at a premium. The digital RC output ensures precise readings, while the maximum current for the LED and board is 3.5mA and 9mA respectively. The optimal range for this sensor array is 10mm.

The QTRX-MD-03RC Reflectance Sensor Array is designed to identify changes in reflectance with pinpoint accuracy. It's an excellent tool for applications such as line detection. The sensor array operates efficiently within a voltage range of 2.9V to 5.5V. It also offers the advantage of dimmable brightness control, which remains independent of the supply voltage.

What sets this version apart is the use of high-performance, low-current QTRX sensors with lenses. These sensors increase the overall efficiency and reliability of the array. In general, the closer the object to the sensor, the higher the contrast between light and dark readings. However, this array can detect high-reflectance objects up to approximately 30mm away. This makes the QTRX-MD-03RC Reflectance Sensor Array a versatile and valuable tool for a wide range of applications.

In summary, the QTRX-MD-03RC Reflectance Sensor Array from Pololu is a compact, efficient, and reliable solution for detecting changes in reflectance. Its high-performance sensors, dimmable brightness control, and ability to detect high-reflectance objects from a distance make it stand out in the market.
