Hello
in the data sheet of LPS22HH the absolute accuracy is ±0.5 in which range of pressure ? ( 800 hPa to 1100 hPa) ? because i tested some samples in 0.3 bar and 0.5 bar, there big difference between the mesure of LPS22HH and reference (exactly values).
Thanks

Hi @ljm ,
The absolute accuracy refers to the whole pressure range. In the range of 800hPa to 1100hPa the relative accuracy, as stated in the DS mechanical characteristics, is 0.025hPa.
Can you please share some examples (graphics) of you measurements? And also with the registers setting of the pressure sensor, so that we can better investigate your case.
We would like to see both pressure and temperature output of the sensor and reference values.
