Overview

The LIS3DHTR is an ultra-low-power high-performance three-axis linear accelerometer belonging to the nano family. It provides digital I2C and SPI serial interface standard outputs and is capable of measuring accelerations with output data rates from 0.5Hz to 625Hz.

Why Choose This Part

This sensor features an extremely low power consumption of 2uA in low-power mode, making it ideal for always-on battery applications. It includes an integrated 32-level FIFO buffer and two independent programmable interrupt generators to reduce host processor overhead.

Applications

Motion-Activated Functions
Detects movement to wake up battery-powered devices from sleep mode, extending battery life in IoT sensors.
Display Orientation
Automatically switches between portrait and landscape modes in handheld devices and tablets.
Free-Fall Detection
Triggers data protection or safety mechanisms when a device is dropped.
Vibration Monitoring
Provides 6D/4D orientation detection and impact recognition for industrial equipment and smart home appliances.
