Airmar PB200 WeatherStation power usage

I've measured actual power usage for the expensive but all-encompassing-all-but-dancing-and-singing Airmar PB200 WeatherStation NMEA 2000 sensor.

It is officially stated as a 13 LEN device which means that it could use up to 13 * 50 = 650 mA @ 12 V = 7 W, but it actually only uses 2.5 W, e.g. 4 to 5 LEN. That's OK for a sensor that does all of the following:
  • GPS (WAAS, EGNOS) (it even claims to do GLONASS according to its PGN 12029)
  • Heading (rate stabilised)
  • Pitch & Roll
  • Wind direction and speed
  • Temperature
  • Air pressure

  1. do you have plans to post or share the code for your linux or windows packet-logger. ?? I am working on building a B&G 2000 replacement with a small low power processor running linux (TS-7500) and your code would be of help as I am planing to use only NMEA2k for the interface.
