Need advice on using LabView for measuring airflow to volume project

[sergy3]

So I have a MEMs bidirectional airflow sensor (still need to decide on one and buy it) and i am i have been told that with lab view i can find the volume based on the user's inhale/exhale data. I am basically new to this software. And to transfer the data from sensor to lab view i still need to figure out.

In a perfect world i am picturing it in my head like this:

• User breathes
• collect/store data
• analyze inhaling/exhaling in labview to get volume

i am figuring out how to analyze the data that the user is breathing so all i am wondering is how to find the volume of the mass flow. For now this is NOT in real time so i assume i would use a USB to get it from the sensor and later analyze on a computer

Can this be done and how?

Thanks

It all starts with the device you choose and how it communicates.  Many devices will use the USB connection to make a Virtual Serial Port.  So it is just simple VISA calls from there.  Hard to give any more advice until you decide on your sensor.

You integrate the flow speed over time. 🙂

Keep the media temperature (aka density) into account when you want to calculate volume from mass flow.

(After all that's basic physics.)

Yes, and humidity and so on, there are formulas for that that i've used.
