LPS22HH Atmospheric pressure strange temperature changes.

[tsuna]

I started to evaluate LPS22HH using STEVAL-MKI109V3, STEVAL-MKI192V1, Pressure LPS22HH Kit, and Unico-GUI. Of the 4 STEVAL-MKI192V1 I purchased, the atmospheric pressure of 2 devices shows strange temperature changes.

LPS22HH press =4.3268t+879.71[hpa]  t:Celsius

Attach the Save data of Unico-GUI.(Settings Low Noise Enable, 1Hz,ODR/9)

The measured environment is my work room, and I expect that the barometric pressure change will be within 1 [hPa] in a short period of time.

Hi @tsuna​ ,

the data are showing an increasing of the temperature together with increase in pressure. This is physically correct, you are evaluating these two environmental values in a single point, and they are changing together.
