MWMotion

The BMI270 can detect simple user activities (unknown, still, walking, running) and send an interrupt if those are changed, e.g. from walking to running.

The BMI270 uses the slope between two acceleration signals to detect changes in motion.

Detect when there is no motion for a certain amount of time.

The BMI270 can detect motions including walking, biking, sitting in a moving car, coach or train, etc. Situations that don’t typically trigger include phone in pocket while stationary or phone at rest on a table which is in normal office use.

Lux (Illuminance)

The haptic module controls a high current driver to power a motor or buzzer (or similar devices).

In the MMR+ model, the coin vibration motor provides haptic feedback. It does not provide pulse-width modulation capability.

Celcius

Emits steps detected in 20 step intervals.

Emits each time a step is detected, leaving summation to you.
