Bosch Sensortec has launched a barometric pressure sensor for smartphones, wearable and hearable devices. The BMP390 delivers altitude tracking in smartphones as well as wearable and hearable devices.

The change in the rate of potential transpiration with elevation is modified in both degree and direction by the character of the temperature lapse rate. Under isothermal, and much more so under ...

From 1979 to 2019, the air pressure near the peak of Everest ranged anywhere from 309 to 343 hectopascals — roughly one-third the pressure at sea level — depending on the season.

A Barometric Pressure Estimator (BPE) algorithm was implemented in a production speed-density Engine Management System (EMS). The BPE is a model-based, easily calibrated algorithm for estimating ...
