SMI230 | Combined inertial sensor for non-safety relevant applications

Flexible
accelerometer and gyro can be operated individually, but can also be tied together for data synchronization

The SMI230 detects acceleration and angular rates in three perpendicular axes and allows tilt, motion, vibration, or shock sensing regardless of the mounting orientation of the sensor.

In particular, it eliminates the need for different sensor housings for slant-angle correction.

Benefits

High accuracy - best in class accelerometer and gyro

Cost-effective

Ultra compact sensor design gives small footprint

Low power consumption - also at system level

RoHS compliant

AEC-Q100 Grade 2 qualification

Target applications

High-end navigation (dead reckoning) and eCall

Telematics and tolling systems

Vehicle dynamics data logging
