A gesture recognition sensor module capable of detecting nine distinct hand gestures including directional swipes, rotation, and waving. The module communicates via I²C and features both normal and game modes for different gesture speed sensitivities, making it a versatile input device for interactive projects.
With a detection distance of up to 10 cm and ambient light immunity up to 100k lux, the sensor works reliably in a variety of lighting conditions. Connect via the standard 5-pin header to any 5 V microcontroller.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- lux
- Lux is the standard unit for measuring how much light falls on a surface, similar to how a light meter reports brightness. A sensor that outputs lux gives readings that are easier to compare between rooms, outdoor conditions, and different projects.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
