Overview
The LIS3DH is an ultra-low-power, high-performance three-axis linear accelerometer from STMicroelectronics, belonging to the ‘nano’ family. It features a digital I2C/SPI serial interface and is designed for advanced power saving and smart embedded functions. The device is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz and has dynamically user-selectable full scales of ±2g/±4g/±8g/±16g. It also includes a self-test capability and can generate interrupt signals based on inertial wake-up/free-fall events and device position.
