AIRDUINO DONGLE V.5 (USB Connection) Barometer and Air Temperature Instrument
The all new Connected at Sea AIRDUINO DONGLE V.5 is a weather instrument that outputs NMEA 0183 barometer and air temperature data via USB directly to a computer for seamless integration with both OpenCPN's and qtVlm's free marine navigation software.
Pressure data can be displayed in OpenCPN's Plots Plugins which requires the NMEA 0183 “MDA” sentence.
The NMEA 0183 talker sends XDR, MDA and MTA sentences in a 4 second rotation at 38400 baud.
Example NMEA0183 sentences:
XDR - Pressure (hPa) - $WIXDR,P,1.00053,B,BAROMETER*3E
MDA - Pressure (hPa) - $WIMDA,,,1.00401,B,,,,,,,,,,,,,,,*12
MTA - Air Temperature (°C) - $WIMTA,19.40,C*27
XDR - Air Temperature ( °C) - $YXXDR,C,26.80,C,AirTemp*1B
These high precision digital sensors have typical atmospheric pressure accuracy of ±1.0 mBar and relative accuracy of ±0.12 mBar. Operational range between 300 - 1100 mBar.
The air temperature sensor has a typical accuracy of ±0.5°C at 25°C and operational range between -40 to 85°C. Calibration of the sensor is performed from METAR data.
The AIRDUINO DONGLE V.5 is housed in 10cm x 2.5cm x 2.5cm case with a 160cm USB cable.
