Absolut pressure sensor / MEMS / compact

ST's ultra-small silicon pressure sensors incorporates the unique MEMS technology. The sensors come in highly compact and thin packages, yet are able to give measurements of pressure with extremely high resolution measurements, and can also measure altitude.

STs pressure sensors are suitable for enhancing GPS for indoor and outdoor navigation and for accurate altitude measurement. They can also serve as a barometer in weather stations, smartphones, sports watches, tablets, and automotive as well as industrial applications.

The sensors are based on STs VENSENS technology principle. This enables fabrication of the sensor on a monolithic silicon chip, thus improving dependability and removing wafer-to-wafer bonding.
Integrated mechanical stoppers protect the membrane, which is smaller in comparison to conventional silicon micro-machined membranes, from breaking.

In determination of altitude, system accuracy can be negatively affected by noise. ST has minimized the sensor noise to lowest level possible. This helps in finding out differences within centimeters of altitude variations.
