Compatibility with ST's LSM6 family of 6-axis IMUs (Inertial Measurement Units) simplifies upgrading or scaling of existing designs to add magnetic-field detection for functions such as e-compass and orientation sensing. Product developers can also upgrade current designs that combine a 6-axis LSM6 device with a discrete magnetometer to achieve a space-saving, simplified and reliable integrated solution based on the LSM9DS1.
Compared to earlier 9-axis sensor modules in the 4mm x 4mm LGA package, the LSM9DS1's footprint of 3.5mm x 3mm saves over 5mm 2 of pc-board space. This reduction in area, combined with the low package height of only 1mm, is valuable to designers seeking to add extra functionality in smartphones or create innovative new products in comfortable, wearable form factors, including glasses.
At the same time, the device has 30% higher magnetometer resolution, due to ST's latest low-noise process technology, as well as 20% lower overall power consumption. ST's advanced technology also delivers a significant reduction in accelerometer zero-g offset, to below 100 milli-g, and reduces typical gyroscope rate noise to 0.008 dps per square root of Hz at low full-scale. These improvements enable any mobile device such as a smartphone, tablet, controller or various wearables including smart glasses to support accurate motion tracking, efficient and reliable contextual awareness, and precise orientation and heading. ST's latest MEMS process technology also contributes to power savings in combination with smart power-management modes which, together, reduce typical operating current to just 2mA.
