SMI230
Combined inertial sensor for non-safety relevant applications
Application & Technical Summary
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.
Product 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
- Car alarm
flexible
accelerometer and gyro can be operated individually, but can also be tied together for data synchronization.
