The sensor on Grove - Gesture is PAJ7620U2 that integrates gesture recognition function with general I2C interface into a single chip. It can recognize 9 basic gestures, and these gestures information can be simply accessed via the I2C bus.
Application: You can use Gesture as an input device to control another grove, or a computer, mobile phone, smart car, robot, and more with a simple swipe of your hand.
