Sharp GP2A25J0000F Close-range Reflective Sensor Overview
The 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 Sharp GP2A25J0000F may be used to output a simple digital interface like a pushbutton, with a high-low transition when activated.
See the video under Additional Resources for a BlocklyProp pseudocode example.
