Breath Detection Using Pressure Measurement

Pressure Sensors for Breath Detection

Pressure Transducer SM5470

SM54XX-thumbnailSeries SM5430 and 5470 absolute pressure sensor configurations for a broad range of high volume, OEM manufactures of various consumer, automotive, medical, and industrial products.

Package: SOIC-16

Micro Flow Low Differential Air Pressure Sensors

Microbridge-design-newsThe MB-LPS1-01 Series of low microflow pressure sensors measure differential air (or other non-corrosive gas) pressure, inferring differential pressure from nano-liters per second gas-flow through an integrated airflow channel having high flow impedance.

Low Pressure Sensor STX13A-VLP .5 to 4" H2O

stx13a pressure sensor for under 4" of H2OSTX13A sensors come with a calibrated voltage output for pressure measurement under 4" of H2O.  Dual in-line package, calibrated span and offset. Low voltage input (2.7V - 3.3V or 4.5 - 5.5V)

Pressure Transducer SM5651/5652

SM5651-5652-thumbnailThe SM5600 Series of OEM pressure sensors are fully calibrated, temperature-compensated pressure transducers in dual in-line packages for printed circuit board mounting.

Package: SOIC-16

SLP35A-LP .3-3 psi

slp33smlSLP35A-LP sensors come with a calibrated voltage output for pressure measurement of .3-3 psi.  With a footprint of 10 mm by 10.2 mm and a height of 10 mm, these sensors are extremely small!  Gauge or differential.

MS5701 Differential & Gauge Digital Pressure Sensor ms5701 digital low differential or gauge pressure, I2C or SPI interfaceMS5701 digital pressure sensor with I2C or SPI interface measures gauge pressure from 5 mbar (2" H20) up to 50 mbar (20" H2O). Differential pressure from 2.5 mbar (1" H2O) up to 25 mbar (10" H2O).
