What environmental tests are needed for automotive pressure sensors?

The reliability of electronic products is very high. As a complex vehicle, the harsh environment ( transportation, storage, work, climate , etc. ) tests whether the automotive electronic system can meet the requirements. Bao Haotong introduces you to the automotive pressure sensor environment experiment?
