This GR10-30 gesture sensor is capable of recognizing 12 hand gestures: move up, down, left, right, forward & backwards, rotate clockwise & counterclockwise, rotate clockwise & counterclockwise continuously, hover, and wave. Users can set parameters such as the gesture trigger distance, the hand rotation angle and hovering time, and the size of the recognition window to get more accurate results.

The GR10-30 gives a stable performance and high accuracy within a sensing distance of up to 30cm. Meanwhile, it provides two interrupt pins for indicating if a gesture trigger occurs and if an object enters the recognition range.

Most gesture recognition sensors use the PAJ7620U2 chip, which has a recognition distance of 20cm and supports 9 types of hand gestures (compared to GR10-30, which lacks three gestures: clockwise and counterclockwise continuous rotation, and hovering).

The sensor is well suited to non-contact operation applications like gesture remote controllers, robot interaction, human-machine interface control, and lighting control.
