Gravity I2C Triple Axis Accelerometer – LIS2DH (±16g)
Product Description
The Gravity I2C Triple Axis Accelerometer – LIS2DH is an ultra-low-power 3-axis linear accelerometer module based on the LIS2DH MEMS sensor. It provides accurate acceleration measurement across X, Y, and Z axes with selectable measurement ranges up to ±16g. The module uses the Gravity I2C interface for easy plug-and-play integration with microcontrollers such as Arduino, ESP32, Raspberry Pi, and more.
Key Features
- Gravity plug-and-play I2C interface — no soldering required.
- Wide operating voltage: 3.3V – 5V (with onboard level conversion).
- Ultra-low power consumption: as low as 2 µA in low-power mode.
- Adjustable sensitivity: ±2g / ±4g / ±8g / ±16g.
- 16-bit digital output for precise acceleration data.
- High response rate up to ~5.3 kHz.
- Embedded temperature sensor and FIFO buffer.
- 2 independent interrupt generators for motion and free-fall detection.
- 6D/4D orientation detection supported.
- High impact resistance (~1,000,000 g).
