Gravity: GR10-30 Gesture Sensor (UART & I2C, 12 Gestures, 0~30cm)
This GR10-30 gesture sensor is capable of recognizing 12 hand gestures: move up, down, left, right, forward, backward, rotate clockwise and counterclockwise,...
This GR10-30 gesture sensor is capable of recognizing 12 hand gestures: move up, down, left, right, forward, backward, rotate clockwise and counterclockwise, rotate clockwise and counterclockwise continuously, hover, and wave. And users can set parameters such as the gesture trigger distance, the hand rotation angle, the hovering time that can be recognized, and the size of the recognition window to get more accurate results.
The GR10-30 features stable performance and high accuracy within a sensing distance of up to 30 cm. Meanwhile, it provides two interrupt pins for indicating if a gesture trigger occurs and if an object enters the recognition range.
The sensor is well suited to non-contact operation applications like gesture remote controllers, robot interaction, human-machine interface control, lighting control, and gesture game machine.

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
