LPS331AP

high-resolution MEMS

pressure sensor

LPS331AP pressure sensor enables 3D indoor positioning and enhanced

GPS in portable devices

From 750 m below ground

to the top of Mount Everest,

smartphones and other portable

devices will soon be able to

pinpoint their height relative

to sea level to better than one

meter, using the most recent

MEMS (micro-electromechanical

systems) pressure sensors

from STMicroelectronics. The

new LPS331AP is a tiny silicon

pressure sensor that provides

high-resolution measurements

of pressure in an ultra-compact

package ideal for use in

smartphones, tablet PCs and

handheld GPS.

Key features

260 to 1260 mbar absolute

pressure range

High-resolution mode:

0.020 mbar RMS

Low power consumption:

•

High overpressure capability:

20x full scale

Embedded temperature compensation

Embedded 24-bit ADC

Selectable ODR from 1 Hz to 25 Hz

SPI and I

Supply voltage: 1.71 to 3.6 V

High shock survivability: 10,000g

... Sensor bias evaluation Kit ST’s pressure sensors are supported by an evaluation kit that consists of a motherboard (STEVAL-MKI109V2) and a plug-in module that includes the LPS331AP sensor (STEVAL- MKI120V1). Once the adapter is plugged in, the board can be connected to a host PC via USB so the device’s capabilities can be easily evaluated via an intuitive graphic user interface ...
