RE: Benefits of Pressure Sensors for Measuring Airflow

I agree, pressure sensors can greatly improve HVAC implementations.

I have been in buildings where you can physically tell when the system comes on due to pressure changes.

RE: How Pressure Sensors Can Improve GPS Accuracy

OK, given that GPS provides X, Y and Z, you need to provide me a lot more information before I will concede that a barometric sensor is better.

To use a barometric sensor for altitude you have to constantly adjust for local barometer changes due to normal atmospheric conditions.

That is one of the reasons that GPS was used in aircraft because you needed accurate altitude measurements during storms and low visibility conditions.

Interesting application, although I think there are several sticky engineering challenges to make this work well.

It sounds like it would be useful to have 2 air temperature sources available to provide airflow even when there is no need to change the room temperature. This would avoid cooling and heating the same air. (Air flow is needed just to purge CO2 generated by people)

I have worked in clean rooms so you cannot overstate the importance of a clean environment.

RE: Optimizing Air Filtration with Differential Pressure Sensors

Yes, I remember some of the older HVAC systems where you could get high volume of air in bursts instead of a nice steady stream of fresh air.

I wish differential flow and pressure sensors were cheap enough to be embedded into my furnace air filters.
