Overview

The LIS2DH12TR is an ultra-low-power high-performance three-axis linear accelerometer belonging to the femto family. It offers selectable full scales of plus or minus 2g, 4g, 8g, or 16g and is capable of measuring accelerations with output data rates from 1Hz to 5.3kHz. The device features an integrated 32-level first-in, first-out (FIFO) buffer and a temperature sensor, making it a versatile choice for motion-sensing applications.

Why Choose This Part

The component stands out for its extremely low power consumption, drawing as little as 2 microamps at a 1Hz ODR. It supports both I2C and SPI digital interfaces and operates over a wide supply voltage range of 1.71V to 3.6V. Its compact 2x2x1 mm LGA-12 package is ideal for space-constrained designs requiring high-resolution motion sensing.

Applications

Motion-Activated Functions
Ideal for wake-up features in battery-powered devices to conserve energy when the system is stationary.
Display Orientation
Used in handheld electronics to detect screen rotation and adjust the user interface layout accordingly.
Impact and Shock Detection
Suitable for detecting drops or mechanical stress in industrial equipment and consumer logistics trackers.
Free-Fall Detection
Triggers safety protocols, such as parking hard drive heads or logging event data during a fall.

Getting Started

To evaluate this sensor, the STEVAL-MKI151V1 adapter board can be used with the STEVAL-MKI109V3 motherboard for rapid prototyping. STMicroelectronics provides the X-CUBE-MEMS1 software expansion for the STM32Cube environment, which includes drivers and sample code for motion detection. Ensure proper decoupling of the VDD and VDD_IO pins as per the datasheet to maintain signal integrity.
