The Grove Gesture is based on the PAJ7620U2 that integrates gesture recognition function with general I2C interface into a single chip. It can recognize 9 gestures including moving up, moving down, moving left, moving right and more, with a simple swipe of your hand.
We can use the gesture to adjust the sound volume, control a robot, direct an application and more. We can also make a remote-control unit, which is able to operate many devices at the same time using gestures
