I have a question about the temperature compensation of the LPS22HH.

This is the result of getting the pressure value and temperature of LPS22HH.

①1051.5 hPa, 22.5 ℃

②1083. 8hPa, 30.7 ℃

This is the result of obtaining the pressure value of the pressure sensor 2SMPB-02B for comparison.

①1015.3 hPa

②1015.2 hPa

① is the value at a room temperature of 22°C.

② is the value about 30 seconds after heating with a dryer.

I am using STEVAL-MKI192V1.

There is a difference in pressure change due to temperature.

Am I missing some necessary setting?
