m5Stack U127 Gesture Moving Recognition Sensor recognizes up to 9 gestures. It’s a touchless 3D gesture recognition sensor via the I2C interface that integrates with the PAJ7620U2. The user can feel the charm of 9 kinds of gesture recognition by default program. The supported nine gestures are up, down, left, right, front, back, clockwise, counterclockwise, and a quick wave. In addition to adding more complex gestures, the recognition rate is up to 240Hz with higher anti-interference capability. The m5Stack U127 sensor is reliable for its recognition process, is intuitive, and has low power consumption (operating current only 2.2mA). This ability allows the user to control a robot by hand movement. This feature is useful in interactive applications.
