Wireless Ambient Pressure Sensor

A barometric pressure sensor measures absolute atmospheric pressure across 300–1100 hPa. Its trend is the basis of short-term weather forecasting — a fast drop means an approaching front — and alongside temperature and humidity it completes the picture of a site's conditions. The same value is used to estimate altitude and to correct a reference pressure in process calculations. Note that it measures absolute air pressure, not fluid pressure inside a pipe nor the differential between two spaces.
