QTR-MD-04A Reflectance Sensor Array: 4-Channel, 8mm Pitch, Analog Output

The Pololu QTR-MD-04A Reflectance Sensor Array is a 4-channel device with an 8mm pitch and analog output. This compact unit measures at 29.0mm x 20.0mm and is designed to precisely identify changes in reflectance, making it ideal for tasks like line detection. It operates efficiently within a voltage range of 2.9V to 5.5V and offers independent dimmable brightness control. The sensor array requires a maximum current of 30mA for the LED and 62mA for the board. It performs optimally within a range of 5mm, however, high-reflectance objects can be detected up to approximately 40mm. The QTR-MD-04A model comes without lenses.

The Pololu QTR-MD-04A Reflectance Sensor Array is perfect for robotics and automation projects that require precise detection of changes in reflectance. Its compact size, coupled with its wide operating voltage range, makes it versatile and easy to incorporate into a variety of designs. The device's ability to control brightness independently of the supply voltage is a unique feature that allows for better adaptability to different operating conditions.

One of the greatest benefits of the QTR-MD-04A Reflectance Sensor Array is its ability to detect high-reflectance objects up to 40mm away. This makes it a reliable choice for tasks that require a higher degree of precision and sensitivity. The absence of lenses in this model also contributes to its efficiency, as it reduces the risk of optical distortion and allows for more accurate readings.

Pololu's QTR-MD-04A Reflectance Sensor Array stands out for its quality and performance. Whether you're building a line-following robot or designing a complex automation system, this sensor array is sure to deliver accurate and reliable results, making your project a success.
