I want to make air flow sensor

sbrn

Hello I want to make a sensor system to monitor wind speed in natural windows.

I want to make a sensor to save costs.

 

Do you have any suggestions for a measurement method for the sensor?

 

So far there are two possible methods, namely by plate orifice and ultrasonic. I want a sensor that can tell the wind speed and its direction (in / out) so that it is inclined to the orifice plate which takes advantage of the pressure difference. However, I still have trouble choosing the appropriate sensor because I estimate that the pressure difference is relatively small.

 

Can you guys suggest sensor options for me?

 

Thank you

    So what you have is two design challenges, namely air flow speed and air flow direction. I would suggest starting with the simpler? design challenge of finding a solution that can determine direction of air flow before getting to measure air flow speed. As you say this could be determined be measuring the slight pressure difference between inside and outside of a building but that you cannot find a sensor sensitive enough.

     

    In my view, if a sensor cannot be found then the trick is to design a method to channel the air flow through a tighter space to increase the pressure difference. As that article demonstrates, this usually means making a separate enclosure or housing for the sensor of choice to provide you with more meaningful data. As to how this is done in the real world - well, unfortunately, I don't have an immediate answer.
