The Gravity: LIS331HH is a high-performance 3-axis linear accelerometer with ultra-low power consumption of just 10 µA in low-power mode. It offers user-selectable measurement ranges of ±6g, ±12g, or ±24g and delivers 16-bit data output with configurable data rates from 0.5 Hz to 1 kHz.
Using the Gravity I2C interface, the sensor connects without soldering and features a toggle switch for changing the I2C address, making it easy to use multiple sensors on the same bus. Built to survive shocks up to 10,000g.

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
