The PAJ7620U2 Gesture Recognition Sensor Module is an intelligent optical sensor designed for motion and proximity-based applications. Capable of recognizing up to 9 intuitive hand gestures—including directional swipes, circular motions, and waving—it enables touchless control interfaces for a wide variety of electronic systems. This makes it a perfect solution for IoT projects, smart home automation, and robotics. The module supports I²C communication at up to 400 kbit/s, allowing seamless integration with microcontrollers such as Arduino, ESP32, Raspberry Pi, and STM32. Its high-speed recognition (up to 1200°/s in gaming mode), combined with ambient light immunity up to 100,000 Lux, ensures reliable performance even in bright environments. With low power consumption and a compact form factor, the PAJ7620U2 offers an efficient and responsive solution for gesture-based control systems. Featured By RoboticsBD.
