Grove - Gesture Sensor for Arduino (PAJ7620U2)

The Grove Gesture Sensor is an easy-to-use module that enables hand gesture recognition through a dedicated PAJ7620U2 sensor chip. This integrated sensor detects common hand motions such as swipes and directional movements and outputs corresponding gesture information through a standard I²C interface. The compact Grove-compatible design allows you to instantly connect it to supported development boards, including Arduino and Seeeduino, without complex wiring.

This module is ideal for human–machine interaction (HMI), touchless control systems, gesture-based user interfaces, robotics, smart devices, and wearable electronics. It supports real-time gesture recognition and is suitable for interaction projects where contactless control using hand movements is needed.

Key Features

• PAJ7620U2 Gesture Recognition Sensor
  Built around the PAJ7620U2 chip that integrates gesture detection and I²C communication.
• Recognizes 9 Common Gestures
  Capable of detecting gestures including Up, Down, Left, Right, Forward, Backward, Clockwise, Counter-clockwise, and Wave.
• Grove Plug-and-Play Interface
  Utilizes the standard Grove connector for quick and clean connection to Grove systems and compatible development boards.
• Easy I²C Communication
  Gesture data is delivered via I²C bus, making it easy to integrate gesture control into Arduino and other microcontroller projects.
• Compact Form Factor
  Small footprint (approximately 20 × 20 mm) for embedding in interactive and space-constrained projects.
• Wide Operating Conditions
  Supports a 5 V power supply, operates in various ambient light conditions (up to high lux levels), and is reliable across typical embedded-system temperatures.
