WeatherDuino is compatible with Davis anemometers, why special development? (If I understood your message )

Hello Toby,

I think I can answer your question: The ultrasonic anemometer model we are talking here isn't the Davis Compatible model, instead its a model with a digital output (look the specs some posts above). Communication with the device is done using the MODBUS protocol through an RS485 line, thus the need of a specially developed hardware to work with RS485 MODBUS devices.

Regards
