Summary

STMicroelectronics LIS3DH 3-axis accelerometer with SPI interface for motion sensing applications.

Description

The **LIS3DH Accelerometer** provides 3-axis acceleration data with programmable full-scale ranges, data rates, and tap detection functionality. It features configurable resolution modes, power settings, and supports both single and double tap detection with adjustable thresholds and timing parameters. The sensor communicates via SPI interface.
