DFRobot_MGC3130

• 中文版

The DFRobot 3D gesture sensor is an interactive sensor that integrates 3D gesture recognition and motion tracking. This sensor can be used to detect clockwise/counterclockwise rotation and movement directions. It is based on Microchip patent GestIC® technology with electric near field sensing technology, including 3D gesture input sensing system and advanced 3D signal processing unit. And its effective detection range is 0-10cm.

Summary

The library provides three samples: gesture recognition, touch recognition and proximity position monitoring

Gesture recognition: left --> right, right --> left, up --> down, down --> up

Touch recognition: single-click, double-click or touch the up, down, left, right or center key

Proximity position recognition: position data in the X, Y and Z axes

Installation

There are two ways to use the library:

1. Open the Arduino IDE, search for "DFRobot_MGC3130" in Tools --> Manager Libraries on the status bar, and install the library.
2. First download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in that folder.
