MEMS Inertial Measurement Units
Micro-Magic's cost-effective MEMS IMUs combine three axes of accelerometers and gyroscopes with sophisticated Kalman filtering to provide comprehensive real-time data on orientation, velocity, and acceleration. Certain models also offer accelerometers and barometers, as well as IP67 or IP68-rated ingress protection against dust and moisture.
