Pressure Sensors Infiltrate Unique Markets

Dec. 16, 2010
The LPS001WP silicon pressure sensor employs MEMS technology to provide high resolution measurements of pressure and altitude.

The LPS001WP silicon pressure sensor employs MEMS technology to provide high resolution measurements of pressure and altitude. Available in an ultra-compact and thin package, it is highly viable for use in smart phones, sports watches, weather stations, automotive and industrial applications, and other portable equipment. The sensor consists of a flexible silicon membrane sitting above an air cavity with a controlled gap and defined pressure. Protected from breakage by built-in mechanical stoppers, the membrane includes a piezoresistor. Its change in resistance is monitored, thermally compensated, and converted to a digital value. The device specifies an operating pressure range of 300 to 1100 millibar, corresponding to the atmospheric pressures between -750 and +9000m relative to sea level, and can detect pressure changes as small as 0.065 millibar, corresponding to 80cm of altitude. Price is $2.80 each/1,000. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
