QTR-HD-01RC Reflectance Sensor: 1-Channel, 5mm Wide, RC Output

The QTR-HD-01RC Reflectance Sensor is a compact and efficient solution for detecting changes in reflectance, such as line detection. With its dimensions of 5.0mm x 20.0mm, it features a single sensor and RC (digital) output. The sensor operates optimally within a range of 5mm and requires a maximum current of 30mA for the LED and 32mA for the board.

The sensor operates from a voltage range of 2.9V to 5.5V, offering the advantage of dimmable brightness control, independent of the supply voltage. This means you can adjust the brightness of the LED to suit your specific requirements, without having to alter the power supply. This feature enhances the versatility of the QTR-HD-01RC Reflectance Sensor, making it suitable for a variety of applications.

The QTR-HD-01RC Reflectance Sensor is exceptionally precise in identifying changes in reflectance. The closer the object, the higher the contrast between light and dark readings. However, the sensor is capable of detecting high-reflectance objects up to around 30mm. This makes it an ideal choice for tasks that require a high level of accuracy in reflectance detection.

Unlike other versions, this sensor features a traditional-style QTR sensor without lenses. This design choice simplifies the sensor's structure and enhances its reliability. Whether you're a hobbyist building a line-following robot or a professional developing a complex automation system, the QTR-HD-01RC Reflectance Sensor is a reliable and efficient tool for your project.
