Wind sensor

NMEA 2000 interface for ultrasonic sensors

Windy Plug, an NMEA 2000 interface for LCJ Capteurs’ wind sensors, comes with an embedded barometer.

Windy Plug is a Baro Plug with an additional interface to connect any of LCJ Capteurs’ ultrasonic wind sensors to a NMEA 2000 system. It features a Micro C male plug to connect directly to the NMEA 2000 bus. This is a plug-and-play device: after installing the sensor to a NMEA backbone, it lets users immediately read atmospheric pressure, wind speed, wind angle, and wind temperature.

The measurement is displayed in millibar (mbar) or one-tenth of a millibar. It’s also available in inches of mercury (“Hg). The sensor measures pressures from 850 hPa to 1150 hPa to one decimal resolution and sends the relevant data to the NMEA network.

Users may also connect the sensor to NMEA 2000-compatible marine display equipment. For one Windy Plug unit, there are two virtual Windy Plugs; users have to select the required

Windy Plug from the list of the devices connected:

  • WindyPlug V2 (NMEA 2000 V2 before 2014, millibar resolution, 1012 mbar)
  • WindyPlug V3 (NMEA 2000 V3 later than 2014, one tenth millibar resolution, 1012,2 mbar).

LCJ Capteurs (France) designs and manufactures ultrasonic wind sensors. These sensors measure wind speed and direction for recreation and professional use in fields such as leisure marine, heavy marine, mobiles on land, smart buildings, wind farms, sound measurement, environment, or agriculture.

NMEA 2000 for marine sensors

NMEA 2000 is standardized as IEC 61162-3. It is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats. Communication runs at 250 kbit/s and allows any sensor to talk to any display unit or other device compatible with NMEA 2000 protocols. Electrically NMEA 2000 is compatible with CAN. The higher-level protocol format is based on J1939, with specific messages for the marine environment.
