Pololu QTRX-HD-13A Reflectance Sensor Array: 13-Channel, 4mm Pitch, Analog Output, Low Current

The QTRX-HD-13A Reflectance Sensor Array is a 13-channel device with a 4mm pitch and analog output. It's compact, measuring only 53.0mm by 20.0mm, and it operates with a low current, with the LED drawing a maximum of 3.5mA and the board drawing up to 31mA. The optimal range for this sensor array is 10mm. The QTRX-HD-13A is equipped with an array of IR LED/phototransistor pairs that excel at identifying changes in reflectance, making it an ideal tool for tasks such as line detection. It operates within a range of 2.9V to 5.5V and features dimmable brightness control that functions independently of the supply voltage. Additionally, it boasts separate controls for the odd and even emitters. One of the standout features of this sensor array is its high contrast ratio between light and dark readings, which increases the closer the object is to the sensor. Despite this, it still performs well at greater distances, being capable of detecting high-reflectance objects at up to 40mm away. The QTRX-HD-13A Reflectance Sensor Array is a high-performance, low-current device that comes with lenses. This makes it a reliable and efficient tool for a variety of applications, from robotics to security systems, and anything in between. Its precision and versatility make it a valuable addition to any project where accurate reflectance detection is key.
