The reflectivity of infrared light varies with the color and distance of the reflecting surface. According to this principle, Grove - Infrared Reflective Sensor utilizes an RPR220 reflective photosensor module to detect color and distance. When a light-colored object approaches, the signal intensity received by infrared reflective sensor increases and the indicator LED on board turns red. When a dark-colored object approaches, the intensity decreases and the LED turns off.
This sensor is a basic and widely used part in applications such as line-following cars, rotary speed detection, auto data logging on utility meters or other situations where color or distance contrast is sharp.
For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.
Ready to use with microcontrollers as a digital input. This product also has a compact modular design Plug-and-play grove compatible interface.
In the picture above, the grove shield for Arduino is stacked with Seeeduino V4.2. Of course, you can use that shield with Arduino too :)
