I bought the “Weather meter”.
The datasheet say for the anemoter:
The cup-type anemometer measures wind speed by closing a contact as a magnet moves past a switch.
A wind speed of 1.492 MPH (2.4 km/h) causes the switch to close once per second.
But I do not understand, I tested the anemometer and I have 2 contacts per revolution.
Can you confirm the number of contacts per revolution ?
No public wish lists :(
