We are developing an artificial respirator and we use the SMC company PFM711-FO2-B among the sensors. The operating range is from 0.0 PSI to 1.0 PSI. We want to read that value through the digital output of the sensor through an Arduino board.
Which Arduino board?
We found tests to determine cardiovascular risk taking into account lipid profile, blood pressure, age, history of diabetes, other laboratories. But when weight is involved, there is a paradox. I...
