Hello,

I am looking for a simple wind flow sensor based on a NTC 10k thermistor. I need to measure wind speed up 20m/s. The idea is to internally heat thermistor with power supply i.e. 10V. Maybe somebody have done similar circuit for a wind flow sensing?

Hi,

* look through the links in the box "similar threads" below
* search for " thermistor airflow circuit" or "thermistor anemometer circuit"

There are many discussions and circuits available.
