Pressure

BMP585 Barometric pressure sensor
https://www.bosch-sensortec.com/products/environmental-sensors/pressure-sensors/bmp585/
With its extreme accuracy, BMP585 measures a change in height of just a few centimeters.
It can therefore detect movements in fitness training down to the level of individual pull-ups or push-ups.
At the same time, users do not have to worry about environmental conditions - thanks to its extreme ruggedness.

The BMP585 has a gel-filled cavity that allows highest protection against water and other liquids such as chemicals with the suitable integration concept. The sensor can be used for applications like height measurement, water-level detection and navigation with a maximum absolute accuracy of ±50 Pa and an temperature coefficient offset (TCO) of ±0.5 Pa/K.
