BMX055
Absolute orientation sensor combining accelerometer, gyroscope and magnetometer
The BMX055 is a very small absolute orientation sensor in the class of low-noise 9-axis measurement units. All three sensor components of the BMX055 can be operated and addressed independently from each other. On top, the BMX055 integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation measurement, gaming, HMI or menu browser control. All sensor parameters and all settings of the respective interrupt engines can be easily programmed via the digital interfaces.
