Pololu QTRX-MD-05A Reflectance Sensor Array: 5-Channel, 8mm Pitch, Analog Output, Low Current

The QTRX-MD-05A Reflectance Sensor Array is a compact and efficient tool with 5 channels, an 8mm pitch, analog output, and low current. It measures 37.0mm by 20.0mm, operates from 2.9V to 5.5V, and offers dimmable brightness control independent of the supply voltage. With a maximum current of 3.5mA for the LED and 14mA for the board, it provides optimal performance within a range of 10mm.The sensor array is equipped with an array of IR LED/phototransistor pairs, making it an excellent choice for identifying changes in reflectance such as line detection. The closer the object, the higher the contrast between light and dark readings. However, it's worth noting that high-reflectance objects are generally detectable up to around 40mm.This particular version of the sensor array carries the unique feature of high-performance, low-current QTRX sensors with lenses. This feature enhances its performance and reliability, making it an ideal choice for a wide range of applications. Whether your project involves robotics, automation, or any other application requiring precise detection of changes in reflectance, this sensor array is a reliable and efficient tool to use.The QTRX-MD-05A Reflectance Sensor Array offers several benefits. Its low current consumption extends battery life in portable applications, while its analog output allows for more nuanced readings than digital signals. Additionally, its compact size makes it easy to integrate into a variety of systems. With its high-performance QTRX sensors and lenses, this sensor array stands out for its precision and efficiency.
