LIS3DH
MEMS digital output motion sensor with ultra-low power consumption and high resolution for portable devices.
Product Overview
Description
The LIS3DH is an ultra low-power high performance three-axis linear accelerometer belonging to the "nano" family, with digital I2C/SPI serial interface standard output.
The device features ultra low-power operational modes that allow advanced power saving and smart embedded functions. The LIS3DH has dynamically user-selectable full scales of ±2g/±4g/±8g/±16g and 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 LIS3DH 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.

FAE Expert Insights
"The LIS3DH is my top recommendation for battery-powered motion sensing applications. The 2 μA power consumption in low-power mode enables years of operation on coin cell batteries. The embedded FIFO and intelligent interrupt features allow the host microcontroller to sleep while the sensor monitors for motion events. I have helped customers implement step counters, activity monitors, and tamper detection systems with excellent results."
