We found this circuit in an article in Electronics Now magazine from November 1997. The circuit uses two transistors to measure the temperature difference between them when one receives the wind.
In figures 1 and 2 we have two current drains that can be made with operational amplifiers and...
Great sensitivity for the circuit can be obtained with a Darlington amplification step for the...
The used diode is an unusual component today. We found this 12 V regulator in documentation from the...
