Wind Sensor Rev. P

Post by nickmpartz » Sun Feb 10, 2019 2:59 pm

Hi all,

I've got a quick question. I'm trying to understand how the Wind Sensor Rev. P works.
Can someone give me some info about the sensing element connected between JP1 and JP5? (named SENS in the schematic) Is it a small resistor, a small piece of wire or is it something else?


Any help would be much appreciated,
Nick

The sensor is a thermistor, a resistor that changes with temperature.

In a more high end hot wire anemometer it would indeed by a "hot wire" a very thin (and very fragile) wire that is heated.
