Does Atmospheric Pressure Affect Humidity?

· Since the majority of the RH sensors do not have built-in pressure sensor, they are inaccurate above sea level, unless a conversion equation is used with a local atmospheric pressure instrument. The Argument Against a Relationship Between Pressure and Humidity . Nearly all humidity related processes are independent of total air pressure, because water vapor in air does not interact …

Atmospheric Air Analyser - Arduino Project Hub

· Also,Rs = Sensor resistance in displayed gases at various concentrations Ro = Sensor resistance in fresh air. To calculate Ro: We know what the values of a, b are for 'air' (which is typically constant throughout) and also the Rs value, which can be calculated from: Rs = ( Vc/Vout - 1) x RL. Hence from the equation: ppm = a*(Rs/Ro)^b we get:
