STMicroelectronics IIS2DH 3-Axis Accelerometer

STMicroelectronics IIS2DH 3-Axis Accelerometer features ultra-low-power, high-performance and digital I2C/SPI serial interface standard output. The IIS2DH has selectable full scales of ±2g /±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1Hz to 5.3kHz. It can be configured to generate interrupt signals by two independent inertial wake-up/free-fall events and by the position of the device itself. The self-test capability allows sensor functionality checking in the final application. STMicroelectronics IIS2DH is available in a small thin plastic LGA package and operates over a -40°C to +85°C temperature range.
