Question

LPS22HB gives inconsistent readings

Please refer this thread. I don't think that the sensor can get damaged in such short period of time. Is it possibly due to moisture? At times I get 1018hPa which is even higher than sea level pressure of 1013.5 hPa

Pls help.

    Hi @DGand.2​ ,

    Welcome to ST Community!

    On pressure sensors there are very small holes on the silicon exposed cap area of the package to allow external pressure to reach the sensing element and for this reason they should be kept clear of obstructions, in particular humidity can affect the measures.
