Pressure Sensors

ST's ultra-small silicon pressure sensors use innovative MEMS technology to provide extremely high resolution measurements of pressure, and therefore also of altitude, in ultra-compact and thin packages. The devices are designed using ST’s VENSENS technology; this allows the pressure sensor to be fabricated on a monolithic silicon chip, so eliminating wafer-to-wafer bonding and maximizing reliability. The membrane is very small compared to traditional silicon micro-machined membranes and is protected from breakage by built-in mechanical stoppers.

Noise has a considerable effect on system accuracy when determining altitude. ST has reduced the noise of the sensor to a minimum. This enables to detect differences within centimeters of altitude variations.

ST’s pressure sensors are designed to enhance GPS for indoor and outdoor navigation, to measure precise altitude, or as a barometer in smartphones, tablets, sports watches, weather stations, and automotive and industrial applications.

Ultra-thin pressure sensor, dust-free and water resistant

The LPS25HB is offered in a fully molded package that provides the best thermal and mechanical robustness (high shock survivability > 10,000 g) while boosting performance and offering best trade-off between current consumption and noise. The device is built using ST’s new MEMS technology that allows the use of fully molded HLGA (Holed Land Grid Array) packages. Measuring just 2.5x2.5 mm and reaching thinness below 0.8mm, this revolutionary technology eliminates the need for a metallic or plastic cap.
