The AI Visual Gesture and Human Presence Tracking Sensor is a high-performance, offline AI recognition module designed for non-contact interaction. Featuring advanced gesture recognition and head-and-shoulder detection, it identifies up to five distinct gestures and senses human presence within a range of 3 meters. Compatible with Arduino, Raspberry Pi, and IoT ecosystems, it enables seamless, touch-free control in hygiene-sensitive environments, high-noise scenarios, and smart automation systems.

Advanced AI-Powered Gesture Recognition
The sensor accurately recognizes 5 predefined gestures at distances up to 3 meters, enabling intuitive and contact-free interaction. Ideal for applications such as non-contact device operation, smart home control, and interactive public displays.Human Presence and Motion DetectionWith built-in head-and-shoulder detection, the sensor identifies human presence and movement in its field of view. It outputs the number and coordinates of detected upper-body targets, allowing smart devices like fans or lighting systems to dynamically respond to user location—enhancing automation and energy efficiency. Versatile Integration and Seamless ConnectivitySupporting both I2C and UART communication, the sensor integrates easily with various embedded platforms. Operating at 3.3V–5V, it is also compatible with graphical programming platforms such as MakeCode and Mind+, simplifying development and deployment.
