Overview

On sale while supplies last! The Sharp GP2A25J0000F Close-range Reflective Sensor 4-pack is a collection of four optical reflective sensors along with convenient components for building a breadboard interface to a microcontroller. Each Sharp GP2A25J0000F sensor detects changes in white and black surfaces from distances of 1-9 mm,  (0.039-.354” as well as the absence of any object in front of the sensor. Potential applications range from robotic encoders to human-activated sensing for machine activation or reed-switch proximity type applications. The sensor outputs a simple digital interface like a pushbutton, with a high-low transition when activated. This kit includes every component needed to interface the sensor to a microcontroller.   

See the video under Additional Resources for a BlocklyProp pseudocode example.

Features
