Just capture signal isnt good enought without knowing what exactly system send.
"Wind" device basicly have 4 sensors :
1) Wind Speed
2) Wind orientation
3) Outside temperatura
4) Outside humidity
I did some research becouse I need that device to send data via 1-wire network, but finaly I decide to use both information (I like wide LED screen
What sensor is used :
1) Wind speed (reed switch)
Half period on / half period off (not so usual but O.K.)
2) Wind orientation (not sure at the moment)
From outside device come 7 wire, 2 of them are for Wind Speed , so
we have 5 other , 16 orientation of wind , that mean 2^4, 1 wire in 4
out maybe digital/or analog
3) Outside temperature (Normal thermo resistor)
4) Humidity sensor (Low lewel)
Measuring resistance beatween two cooper field
Standard dual reed switch system
If I am on your place I will use rein gouge for testing and alayzing signals.
When I finish 1-wire implementation I will send more info on forum.
