    With dynamic, user-selectable full-scales of ±2g/±4g/±8g, the IIS328DQ can measure accelerations with output data rates from 0.5 Hz  to 1 kHz over a temperature range from -40 to +105 °C.

  • It's small. It's smart. It's our new ultra-low-power 3-axis accelerator

    The ultra-low-power LIS2DS12 MEMS digital output 14-bit 3-axes accelerometer offers embeds real and virtual sensors to provide pedometer and step functions, tilt, timestamp and significant motion detection.
    Able to generate interrupt signals by using hardware recognition of free-fall events, 6D orientation, tap and double-tap sensing, activity or inactivity, and wake-up events, its small size and low power consumption makes the LIS2DS12 a perfect solution for enhancing user experience with the latest mobile apps.

  • You can’t touch this! Or our 3-axis digital accelerometer will know

    The STEVAL-MKI168V1 adapter board helps you evaluate our IIS2DH 3-axis digital accelerometer.
    The board offers developers an efficient way to prototype and evaluate their MEMS-based motion sensor designs for anti-tampering, motion-activated or power-saving applications.
    Fully compatible with the STEVAL-MKI109V2 motherboard functioning as a bridge between the sensor and a PC, developers can use the downloadable graphical user interface (Unico GUI) or dedicated software routines for customized solutions.

  • The world's smallest pressure sensor can survive just about anything

    Delivered in a 2 x 2 x 0.75 mm package, the LPS22HB is not only the world’s smallest absolute pressure sensor, but also the only one offered in a full-molded package that provides the best thermal and mechanical robustness (high shock survivability > 20,000 g) while boosting the performance and offering the best trade-off between current consumption (down to 3µA) and noise (0.0075 hPa RMS).
    Able to function as a digital output barometer, the LPS22HB is guaranteed to operate over a temperature range extending from -40 to +85 °C.

  • New ultra-low-power 6-axis MEMS sensor module for “always-on” motion-sensing

    LSM6DSL is the new ultra-low-power gyroscope and accelerometer combo that thanks to its ultra-low-power consumption of 0.4 mA enables much longer “always-on” motion sensing, boosting the performance compared with the previous generation of iNEMO inertial modules. Featuring a 3D digital accelerometer and a 3D digital gyroscope, this system-in-package ensures an optimal motion experience for the consumer. Supporting main OS requirements, this module offers real, virtual and batch sensors with 4 Kbytes for dynamic data batching.

  • Live long and prosper - says our low-power 3-axis gyroscope

    Developers can take advantage of the continuity of supply for long-life applications with our low-power I3G4250D 3-axis digital output gyroscope.
    The STEVAL-MKI169V1 adapter board lets you evaluate its key features including a selectable full scale (±245/500/2000 dps), an embedded FIFO and programmable interrupt.
    Due to its high stability at zero-rate level and sensitivity over temperature and time, this flexible solution is especially suitable for industrial applications requiring high quality and long-term availability.
