Bosch launches cost-effective movement sensor BMI323



Inertial Measurement Unit (IMU) delivers excessive accuracy and energy effectivity for brand new shopper use instances

  • Movement sensor with no compromises on precision and efficiency
  • Built-in options simplify and speed up product growth
  • New alternatives for IMUs in various shopper functions

Tiny MEMS movement sensors are throughout us. They make shopper merchandise simpler to make use of and enhance how our smartphones and different devices work together with us. These sensors are exact, compact and power-efficient, nevertheless, till now, they’ve been complicated for primary functions. To deal with this concern, Bosch Sensortec is launching the BMI323, an inexpensive Inertial Measurement Unit (IMU) with wonderful efficiency and built-in options enabling a shorter growth time.

“The BMI323’s mixture of simplicity with a superb price-performance ratio will open up new functions for IMUs,” says Dr. Stefan Finkbeiner, CEO at Bosch Sensortec. “These will embody customary shopper merchandise, equivalent to toys, gaming controllers, distant controls, wearables, health trackers, smartwatches in addition to tablets and laptops.”

Like its predecessor BMI160, the brand new BMI323 is a general-purpose, low-power IMU that mixes exact acceleration and angular charge (gyroscopic) measurement with clever built-in options which might be triggered by movement.

Its built-in options make growth sooner and simpler for OEMs. For instance, the BMI323 already contains Bosch Sensortec’s plug-and-play step counter software program, so clients don’t have to spend time growing their very own algorithms. Different options embody movement detection that may flip subsystems on or off when a tool, equivalent to a TV distant management, is put down or picked up, thus lowering total energy consumption.

In comparison with the BMI160, the BMI323 gives improved accelerometer efficiency in addition to decrease energy consumption. In high-performance mode, utilizing each the gyroscope and the accelerometer, the BMI323 has a present consumption of 790µA in comparison with 925µA on the BMI160, which represents a discount of practically 15%.

The 6-axis BMI323 has a self-calibrating 16-bit triaxial gyroscope, a 16-bit triaxial accelerometer, and a 16-bit digital temperature sensor housed in a miniature 2.5 x 3.0 x 0.83 mm (14-pin) LGA package deal that’s pin to pin suitable with the BMI160 and others. The BMI323 is the primary IMU system introduced by Bosch Sensortec to incorporate the brand new I3C interface, along with the I2C and SPI interfaces.


The BMI323 is accessible now.
