Incredibly simple and effective as long as our machine or process is not time sensitive – perfect for a weather station temperature sensor, although wind direction is slightly more complicated.

An curved arrow pointing right. Wind belts around the equator flip about every two years, but NASA has found that a flip occurred much earlier than expected in 2015. Why is up for debate.

They found a 45% growth in convective heat transfer coefficient was possible, depending on wind direction. The Portland group suggested solar plant developers consider predominant wind direction ...
