Product Description
The DFRobot Gravity: PAJ7620U2 3D Gesture Recognition Sensor is a compact gesture recognition sensor module for touchless control concepts in embedded and prototyping applications. It is based on the PAJ7620U2 sensor IC and uses an I2C interface, which simplifies integration with microcontroller and SBC platforms such as Arduino, ESP32, and Raspberry Pi.
The module detects up to 13 different hand gestures at distances from 3 to 20 cm. Supported patterns include directional movements, circular motions, and wave-type gestures. With an update rate of 120 Hz, the module is intended for applications that require fast response and repeatable gesture detection. The source information also describes two operating modes: a fast mode for essential gestures and a slow mode with extended gesture recognition.
Technical Features
- Sensor IC: PAJ7620U2
- Supports recognition of up to 13 hand gestures
- Detection distance: 3 to 20 cm
- Interface: I2C
- Update rate: 120 Hz

Application Areas
Typical use cases include touchless control panels, robotics, smart home and smart environment systems, and interactive installations. The module can be integrated into human-machine interfaces where motion patterns are used as input commands. Due to its I2C connectivity, it fits development boards, educational projects, and functional prototypes using optical gesture sensing.
Additional application areas include control functions in compact devices, experimental user interface concepts, and detection of predefined motion patterns in embedded electronics. The ability to adapt recognition parameters supports development of application-specific interaction logic.
