Core Features
The combination of accelerometer and gyroscope inside a single chip enables six-axis motion tracking. Built-in dedicated digital processing engine carries out sensor data calibration, offset compensation and sensor fusion calculation independently, lowering computing burden on the main microcontroller.
Multiple configurable low-power operating modes are supported. Users can switch between high-precision continuous sampling mode and ultra-low power standby mode according to actual application requirements to extend service life of battery-powered devices.
Various motion event detection functions are embedded, including tilt detection, tap recognition, free fall monitoring, activity and inactivity judgment. Once preset motion conditions are satisfied, the chip generates hardware interrupt signals to wake up the host system promptly.
Advanced vibration suppression filtering units are integrated internally to eliminate high-frequency environmental vibration noise, maintaining stable and accurate motion data output in industrial vibration scenarios.
All pins are equipped with robust electrostatic protection circuits. The internal mechanical structure is optimized to resist mechanical shock, adapting to harsh on-site working conditions of industrial equipment.
Timestamp function synchronizes inertial data with system clock, which is convenient for multi-sensor data alignment in complex monitoring systems.
