Wind velocity sensor advice (small and cheap)


I’m working on a project where I’d like to visualize wind forces across someone’s back. I’m looking to build an array of sensors to measure wind velocity or wind pressure at multiple points (10+ locations on the back). I’d like a small, fairly inexpensive sensor with a high sample rate and fairly high accuracy.

Any ideas would be great.
I’ve been looking into some designs for hot wire anemometers, but I’m unsure of the accuracy.

Thanks in advance for any advice.

I looked at a few and Specs said accuracy of 0.3% for one but this is a $1000 unit.

Are you going to buy or build?
