QTR-MD-05A Reflectance Sensor Array: 5-Channel, 8mm Pitch, Analog Output

Pololu presents the QTR-MD-05A Reflectance Sensor Array, a 5-channel device with an 8mm pitch and analog output. This compact unit, measuring just 37.0mm x 20.0mm, is equipped with an array of IR LED/phototransistor pairs, making it perfect for accurately detecting changes in reflectance such as line detection. The sensor array operates between 2.9V and 5.5V and provides independent dimmable brightness control, irrespective of the supply voltage. The maximum current for the LED and board is 30mA and 93mA respectively. The optimal range for this device is 5mm.

The QTR-MD-05A Reflectance Sensor Array is highly versatile and can be used in a variety of applications. Its high-contrast readings make it ideal for close object detection, but it is also capable of detecting high-reflectance objects at a distance of up to 40mm. This makes it a valuable tool in robotics for tasks such as line following or obstacle avoidance.

One of the unique features of this sensor array is its traditional-style QTR sensors without lenses. This design feature enhances the device's performance and reliability. Additionally, the sensor array offers the benefit of dimmable brightness control, which allows the user to adjust the brightness level independently of the supply voltage, providing flexibility in various lighting conditions.

With its compact size, high precision, and flexibility, the QTR-MD-05A Reflectance Sensor Array is an excellent choice for anyone looking for a reliable and versatile sensor solution.
