Sensor Fusion App; Figure 29. Pedometer App - Step Count - ST STEVAL-MKSBOX1V1 User Manual

The accuracy of the Pedometer is Mean Absolute Percentage Error (MAPE)=97.5% with sigma=5 thanks to the
high precision of the
These parameters are appropriate to capture human movement, filter unwanted noise and save battery energy to
extend the potential working time.
The app works with the following ST high accuracy acceleration sensor and operating parameter settings:
• APP DATA INPUT: 3-axis acceleration values
• SENSOR USED:
• SENSOR SETTINGS:
– Low power mode accelerometer
– Power down gyroscope
– Output data rate: 52 Hz
– Full scale: 4 g
• APP DATA OUTPUT:
– Number of steps
– Cadence (number of steps per minute)

Sensor Fusion app

The Sensor Fusion app is based on the sensor fusion firmware algorithm (MotionFX library) embedded in the
MCU.
The app shows the orientation estimation of
