Vielen Dank an alle für die Infos und Ideen
Problem ist gelöst habe nur zu kompliziert gedacht
Hier der funktionierende Code

/*
LPS22HB - Read Pressure
HS300x. - Read Temperature and Humidity

This example reads data from the on-board LPS22HB sensor of the Nano 33 BLE Sense Rev2,
converts the atmospheric pressure sensor values to pressure at sea level, and reads the
temperature and humidity from HS300x sensor
and prints them to the Serial Monitor every 5 second.

The circuit:

  • Arduino Nano 33 BLE Sense Rev2

This example code is in the public domain.
