Fermion: GR10-30 Gesture Sensor (Breakout, UART & I2C, 12 Gestures, 0~30cm)

Fermion GR10-30 Gesture Sensor delivers reliable non‑contact motion recognition for interactive electronics and embedded control systems. The compact gesture detection module identifies multiple hand movements within a sensing range of up to 30 cm, enabling intuitive control without physical buttons or touch surfaces. Adjustable recognition parameters allow developers to fine‑tune responsiveness and accuracy for different environments. Support for both UART and I2C communication enables straightforward integration with common microcontroller platforms such as Arduino, ESP32 controllers, and Raspberry Pi systems, making the compact sensing board suitable for robotics, smart interfaces, and interactive electronics projects.

12 Gesture Recognition Modes

This gesture recognition module detects 12 distinct hand movements including up, down, left, right, forward, backward, clockwise rotation, counterclockwise rotation, continuous clockwise rotation, continuous counterclockwise rotation, hovering, and waving. Compared with many optical gesture sensors that recognize fewer motion patterns, the expanded gesture library enables richer interaction design. Such capability allows embedded systems to interpret complex user commands, supporting intuitive control schemes for robotics interaction systems, smart lighting interfaces, and gesture‑controlled devices.

Adjustable Recognition Parameters

The intelligent sensing board allows configuration of several key parameters including gesture trigger distance, recognition window size, hovering duration, and hand rotation angle thresholds. Adjustable detection parameters provide flexibility when adapting the motion detection module to different application scenarios, environmental lighting conditions, and interaction distances. Developers can optimize responsiveness or precision depending on project requirements, improving gesture reliability in embedded systems, interactive kiosks, and custom human‑machine interface designs.

Stable Detection up to 30 cm

Advanced optical sensing technology enables accurate gesture detection at distances reaching 30 cm, extending interaction range beyond many conventional gesture sensors. Dual interrupt pins provide clear hardware signals indicating gesture recognition events and object entry into the sensing field, simplifying firmware design for responsive interfaces. Reliable long‑distance detection allows the contactless control sensor to function effectively in robotics control panels, interactive installations, and smart appliance interfaces where hygienic touch‑free interaction is preferred.

The compact gesture detection sensor suits projects requiring intuitive, contact‑free interaction. Applications include gesture‑based remote controllers, robotics interaction systems, human‑machine interface panels, lighting control solutions, and gesture‑controlled gaming devices. The flexible communication interfaces and configurable detection parameters allow the sensing module to integrate easily into embedded development platforms, smart devices, and experimental interactive systems.
