Welcome to All Sensors Blog

Welcome to All Sensors “Put the Pressure on Us” blog. This blog will bring out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. This initial blog explores pressure sensing in weather measurements.

Barometric or air pressure – either rising or falling – indicates a change in weather and is usually included in weather reports with temperature, rain or snowfall and wind measurements. While the temperature, rain and wind information is quickly verified by just going outside, the pressure measurement is a longer term issue. The absolute pressure measurement in inches of mercury for the U.S. is typically about 30.00 for a steady reading depending on height above sea level. The rate and amount of a falling barometer indicates how quickly a storm will occur and its severity. Barometric pressure change may be several days or only a few hours before the weather front. Accurate and precise pressure measurements need to consistently resolve a rather small pressure range since the pressure drop or rise from a steady barometer is usually within 00.20 inches of mercury.
