Measures wind speed and direction as well as barometric pressure. Compatible with pypilot for wind-steering modes, and opencpn for display and data logging.
- Output: nmea0183 to usb as virtual serial port
- Output rate: 10hz wind, 1hz pressure
- Precision: 0.1 degree wind direction, 0.01 millibar
- Cable: micro usb (not included)
This is the minimal version without display or enclosure. For a version with display and enclosure see: weather sensors with display
The pressure sensor used is bmp280. This does not include the analog anenometer! The anemometer must use 4 wire type with analog wind direction and digital pulse for wind speed. The actual anenometer is available from other sites such as:
- Davis-6410-Replacement-Anemometer-for-Vantage-Pro2
- Replacement-Anemometer
- Others such as ebay
It is possible to build your own sensors using a potentiometer for wind direction, and a reed switch and magnet for wind speed. For more information about the davis anenometer see: http://www.lexingtonwx.com/anemometer/
