Q:Why the barometer atmospheric pressure value seems never change?
A: For our barometer AW007A, seems this question is confused by some users. The atmospheric pressure changes very little if the weather does not change too much per day. It changes big and obviously only when the weather changes too much, such as the typhoon, rain etc.
To verify the meter works fine or not, simple way is to put the meter into one full air plastic bag then seals it, then press the bag (please see the video).
Usually if the temperature and humidity work fine, barometer will also work fine. "not change" because the bad weather not happened every day, not means it doesn't work.
