MetaMotion C is the motion and gesture tracking platform and comes with sensor fusion ideal for sports and fitness applications.

This sensor is ideal for logging sensor data. Record raw sensor data via Bluetooth at up to 400Hz.

Download the data and access it as a CSV file on your phone, hub, tablet, computer, server, or the cloud.

The board comes with a IP40 white plastic case. There is also an option to add a wrist band or a belt clip.

The board comes in a very small round form factor, 8MB of NOR FLASH memory and sensor fusion with 10 axis of motion sensing (3-axis accelerometer + 3-axis gyroscope + 3-axis magnetometer + barometer/altimeter/pressure).

The sensor fusion combines the measurements from 3-axis gyroscope, 3-axis geomagnetic sensor and a 3-axis accelerometer, to provide a robust absolute orientation vector in form of Quaternion or Euler angles. The algorithm fuses the sensor raw data in an intelligent way to improve each sensors output. This includes algorithms for offset calibration of each sensor, monitoring of the calibration status and Kalman filter fusion to provide distortion-free and refined orientation vectors.

There is an LED, GPIOs, and push button switch on the board.

The board is powered by a CR2032 coin cell battery.

The board is based on the nRF52 SOC from Nordic built around a ARM® Cortex™ M4F CPU and Bluetooth Low Energy.

The off board memory stores the sensor data on the MetaSensor to be retrieved at any time by your Device (Smartphone, Hub, Tablet or PC).

Sensor data is available:

  • as a CSV file on your Smartphone, Tablet, Computer or BLE Device (using the MetaBase App)
  • as a CSV file in the MetaCloud (using the MetaBase App)
  • as a CSV file on the MetaHub (using the MetaBase App)
  • as a JSON array in your own App code (using our Python/C++/C#/Java/Javascript/Swift APIs)
