Epson QMEMSWorking in a pressure sensing range from 50 kPa to 150 kPa, Epson Toyocom’s QMEMS quartz crystal atmospheric pressure sensor offers a total pressure accuracy of ±10 Pa, or about 1/10,000 of a bar. The device performs measurements of barometric pressure in meterological observations; measures differences in elevation in ~1-cm increments using barometric pressure; and detects slight changes in internal pressure resulting from the opening and closing of inside doors and windows. The 25 mm × 25 mm × 20 mm component exhibits resolution of 0.1 Pa, a RS-232C interface, and an operating temperature range from -20­°C to 70°C.
