FO wind sensor pinout - danner - 14-05-2017

I've been searching for hours and cannot locate the pinout for FO wind vane and FO wind speed sensors. I found an excellent illustration with pictures for Davis wind sensors in this sub-forum here but for the life of me I cannot find similar pictures or diagrams for FO sensors. The sensors I purchased are supposed to be replacements for the WS1080.

TIA

It should plug in with no modification, though there are two types of FO anemometers,

And,

I am not sure what the difference is or if they are different pinouts,

But I am fairly sure the one you have should plug straight in. It was the original starting point for Weatherduino some years ago.

Also other info re your rain gauge question earlier.

Yes it looks like those. The problem is there is only 1 port for the wind and I have 2 cords each with their own RJ11. I'll have to cut the ends off and somehow combine them into a single RJ12, but I need to know the pinout in order to do that.

Thank you for the rain bucket info.

I am not sure what the difference is or if they are different pinouts, as far as I can see they are the same electronics just different cable lengths.

Just check the wind vane, normally the anemometer plugs into the bottom of the wind vane and the wire from the wind vane carries both signals to the TX board. (Or vice versa I cannot remember which.) See picture here,

Aha, one plugs into the other. :-) That makes it easier, LOL. Thanks!

If my searching is correct I've adjusted the trim pot to 10.01K ohms, that was the closest I could get it to 10k after many tries, and I have to find a shorting jumper out of one of my old PC's for JP2 because I'm using FO wind sensors.

Just waiting on a few more bits from china and then figure out how to arrange the boards in their enclosures with the wiring. Biggest challenge is going to be the solar power setup for the temp sensor. Should be interesting.

RE: FO wind sensor pinout - JT118 - 14-05-2017

If you want to upgrade try ebay, lots of research grade kit, expensive but accurate. For example,

And

http://m.ebay.co.uk/itm/Texas-Electronics-TR-525I-Electric-Rain-Gauge-Transmitter-Tipping-Bucket-/112366413874

One of many advantages of Weatherduino is that it is configurable to many sensors from the cheapest FO to the most expensive research grade equipment. I work on the principle that the ebay price I pay is between 10% and 20% of new price, as are the above links.

RE: FO wind sensor pinout - danner - 14-05-2017

Eventually I plan on getting the Inspeed wind speed and vane and probably a Davis rain bucket, but for now the FO sensors will work.

I'm more concerned with the temp record anyway so I got a SHT31 sensor for that. And for now it'll be mounted in a davis solar shield until I can figure out a FARS setup for it. But the FARS depends on the batteries and recharging with solar power so all of that needs to get worked out first. :-)

RE: FO wind sensor pinout - JT118 - 14-05-2017

I assume you are considering solar power for the TX board as a whole. (Temp sensor plugs in to TX board). I use a 12v wall plug with long bit of wire. (Cheap and easy, voltage drop isn,t too bad if you are not too far apart and use thick cable) But if you are going the solar route you just need a panel (sized for latitude and weather, big panel in Scotland!)

Panel example,

All matched as you see fit.

RE: FO wind sensor pinout - JT118 - 14-05-2017

Ok My replies are a little delayed, but above will also power a FARS in addition to tx board,  tx board has an out put for FARS. (Davis fan is I think 3v so will need to change voltage if you use that fan.
