Hi!
I have a problem and was wondering if anyone would be able to help me out and guide me in the right direction.
Me and a friend are trying to build a RPi (or maybe Arduino) based weather station and have a wind speed/direction meter that was decommissioned from an airport that we would like to use. Best I can tell it’s an Observator OMC-160(v2?). I’v dug up a manual for it and it looks like it outputs Currentloop ASCII coded output 20 mA or NMEA-0183 version 2.30. Screenshots from relevant parts of the manual below.
As it is right now, the sensor has been wired with the jumper in place (terminals 13 & 14) with wires going to terminals 1-4, so as I understand it should be outputting a currentloop signal with ASCII information.
Would it be possible to read the output form the sensor using a Pi/Arduino and, if yes, what additional hardware would I need to do it (converters/adaptors and such like)? Links to relevant guides or suggestions on what I should be researching would be appreciated. I’v been trying to read up on relevant topics, but so far I’m struggling to get my head around on how exactly the sensor communicates and how to make it work in our project.
Hope this makes some sense. Sorry if this is a dumb/too broad a question, but I’m very much a “n00b” when it comes to things like this and would appreciate some help.
Cheers!
P.S. Full OMC-160 manual if anyone can be bothered to look at it.
P.P.S Sorry if this in the wrong section of the forum.
