- The National Semiconductor data sheet for the LM335 Kelvin Temp.
- sensor shows a "air flow detector" based on comparing the output
- of two sensors, one of which has a large current going throu
- it and is hence subject to self-heating. I'd like to use such
- an idea to build an anemometer, and want to know... is either
- the difference or the ratio of the temperatures proportional
- to wind speed? Any references on heat transfer from a warmed
- object as a function of airflow?
