M5Stack Gesture Recognition Sensor Unit (PAJ7620U2)

The M5Stack Gesture Recognition Sensor Unit is a low-power 3D gesture sensor with support for nine motion gestures, enabling fast and accurate non-contact control for interactive, robotics, and smart automation projects.

The M5Stack Gesture Recognition Sensor Unit is a 3D gesture recognition sensor using the I2C communication interface. It adopts the PAJ7620U2 sensor solution, with the program by default supporting 9 types of gesture recognition. The maximum gesture update frequency can reach 240Hz, and it has a certain level of ambient light interference resistance. It supports custom unit sampling time and can add recognition gesture combinations through program algorithms as needed. The sensor features strong stability, fast recognition speed, high accuracy, and low power consumption (operating current only 2.2mA), making it suitable for various applications such as non-contact remote controls, robot interaction, human-computer interaction games, and gesture light control. This product supports nine gestures: Up, down, left, right, forward, backward, clockwise, counter clockwise and wave. Features
