LIS2DH中文资料MEMS digital output motion sensor: ultra low-power high performance 3-axes femto accelerometer数据手册ST规格书

描述 Description

The LIS2DH is an ultra low-power high performance three-axis linear accelerometer belonging to the “femto” family, with digital I2C/SPI serial interface standard output.
The LIS2DH has dynamically user selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.
The self-test capability allows the user to check the functioning of the sensor in the final application.
The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself.
The LIS2DH is available in small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
