Tiny silicon sensor uses MEMS technology to provide extremely accurate pressure measurements

摘要

Switzerland's STMicroelectronics NV has developed a tiny silicon sensor that is capable of providing high resolution measurements of pressure. It is housed in an ultra-compact and thin package, making it ideal for use in portable equipment, as well as automotive and industrial applications. Based on micro-electromechanical systems (MEMS) technology, the LPS001WP has an operating pressure range of 300-1100 mbar, corresponding to the atmospheric pressure between -750 m and +9000 m relative to sea level, and can detect pressure changes as small as 0.065 mbar, corresponding to 80 cm of altitude.
