Shimmer3 IMU Unit

Shimmer3 is the smallest, slimmest and most robust wearable wireless sensor created by Shimmer to date. The updated module boasts a 24MHz CPU with a precision clock subsystem, making it three times faster than its predecessor.

In developing Shimmer3, we have focussed on creating a powerful and elegant wearable wireless sensor which will provide superior data quality, adding value to your data collection process. We’ve added a smarter enclosure which allows for straps to be quickly clicked into place for a range of wearable applications.

Shimmer3 offers best data quality with integrated 9DoF inertial sensing via accel, gyro, mag and pressure sensor, each with selectable range. Shimmer3 also boasts an integrated motion processor for on-board 3D orientation estimation. 5 coloured LEDs indicate device status and operating mode, as well as indicating Bluetooth streaming functionality.

For existing customers, Shimmer3 modules are backward compatible with the Shimmer2r Dock and Multi Charger. All current development tools and enabling applications will be made compatible with the Shimmer3 platform.
