USB Boat Barometer

$29.99 - $39.99

Sold all over the world, the Connected at Sea USB Boat Barometer outputs NMEA 0183 barometer data via a USB Type C connector directly to a computer for seamless integration with popular marine navigation software such as OpenCPN and qtVlm (amongst others).

Pressure data can be displayed in OpenCPN's Plots Plugins which requires the NMEA 0183 “MDA” sentence.

The NMEA 0183 talker sends XDR and MDA and sentences every second in rotation.

Example NMEA0183 sentences:

XDR - Pressure (hPa) - $WIXDR,P,1.00053,B,BAROMETER*3E
MDA - Pressure (hPa) - $WIMDA,,,1.00401,B,,,,,,,,,,,,,,,*12

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. Calibration of the sensor is performed from METAR data.

The Connected at Sea USB Boat Barometer is housed in 64mm x 24mm x 15mm case.
