Hi ther !
I want to ask you guys if anybody knows about this wind sensor, i found it at ebay with this title : Wind Speed Sensor for Weather Station Model Number WH2080 If someone have a manual or knows what kind of signal got for output?? I want a cheap wind sensor for my arduino project if anybody can suggest me something would be grateful, i want the sensor gives me accuracy to m/sec not just sense of the wind on a switch.
Thank you and sorry for my bad english !
The model number seems to be the model number for the whole "weather station", not just your part. There seems to be plenty of hits on Google for it, including instruction manual. Although the instruction manual is unlikely to mention the communication protocol between the wind speed sensor and the electronic brain unit. It would be worth looking, just in case...
I guess you could experiment with it, see if you can figure it out. There is only about half a dozen possible interface schemes it might use, analog voltage, 4-20 mA current, pulse frequency, serial, I2C, not many other choices.
please provide a link ....
Buying Wind Sensors by themselves to use in an application differant to what they were intended for is risky
for 2 reasons.
If its a wireless sensor as this one appears to be , then you will either have to dismantle the sensor to figure out
how the wind speed direction and speed are detected, or you will have to reverse engineer the radio protocol that the sensor uses.
Even if you can get this all working, you will have to figure out the relationship between the spin rate of the anemometer and the actual wind speed, and this is not easy to do.
Unless the Wind Sensor comes with a calibration chart which shows the relationship, then you will have to calibrate the wind sensor to get the wind speed correct.
Try and buy a wind sensor from a reputable supplier who will provide the calibration data if you want accuracy.
The wind sensor has a "433MHZ with RCC" interface if it is ASK or FSK modulation doesn't the web site tell, you have to google a bit by your self!
I found this info via googling for 2 minutes!
