Hi All,
I have an AWS ( automatic weather station )which wirelessly transmits , temp ( inside & outside ), humidity ( inside and outside ), rainfall, dew point, wind direction and strength , all to a display in my house.
What I would like to do ( dont know if this is possible or if I am up to it ) is to contruct a unit that could also receive this information from the AWS and then feed it to an Arduino so that the info can then be used / passed to a dew heater ( which I already have ) on my telescope so that as the dew point gets reached the dew heater will automatically come on. I am currently using my Arduino to control the focus function of the telescope and this seemed like a good idea if feasable.
The receiver in the display is a DCF77 if this helps and the transmitter operates at 868Mhz .
Any info would be greatly appreciated, you will see from my post count that I am a noobie so be gentle ..
Rgds

Technically this is possible, but you have to know the frequency it transmits (possibly 433Mhz). This should be described in the documentation, so can you provide more information about the AWS? Type, URL, datasheet etc.
Second part is if you have a receiver and are able to receive, you have to decompose the data stream into its functional blocks, not trivial, but doable most of the time.
DCF77 is a time protocol, send over Europe from a radiobeacon. It only contains time information, no weather info (AFAIK)
Hi PaulS,
That is probably true but as I already have the information streamed to my display I thought
I might be able to use that information to hand.

Hi John, the US has a similar long wave time station (WWVB) which I use for a time standard through the Arduino. A couple of years ago there was some discussion about it on this forum. You could do a search for that.
As far as the other information, if you can find in your indoor display where the output of the receiver is, you might be able to tap off of that to feed an Arduino for display. Is that what you had in mind or did you want to get completely away from the inside display?
Hi Emily Jane,
I would really have preferred to get away from the Display unit, it uses a usb to into my PC so there may be an
easy way there although I wanted a seperate feed ( intercept the outgoing transmission) and then send to the Arduino>
to the telescope dew heater. I am very early into the project and first just wanted to establish if it is feasable.
Would that thread be on the old forum ??
How do you get your time standard into your Arduino ??

I'm not too familiar with your ISM band but I'm fairly confident that you can buy a receiver module to pick up the signal and feed it directly unto an Arduino.
Would that thread be on the old forum ??
It was a couple of years ago so probably yes.

I bought a receiver module and fed the output into the Arduino. The time code is well documented and I just decoded it. I bought my receiver from the manufacturer but I see Sparkfun has them now. Of course, mine is the US version. The manufacturer is called C-Max and I am almost certain they make a receiver for the German standard as well.
