I own a 2005 Davis Vantage Pro 2 that has a defective T/H sensor (7346.029). Since that part is no longer available I was wondering if anyone has any ideas on a replacement sensor. I am looking at maybe changing the ISS board out (7346.070)  so I can add a newer T/H sensor (7345.951) but am looking at approximately $250 expense. I was also thinking about adding a Davis model 6332 Anemometer/sensor kit ($150) and then a T/H sensor (7346.070) for $55. Any ideas and input would be appreciated.

Regards,
Bob]]>

I suggest you look there: https://www.yr.no/en/forecast/daily-tabl...ity/Cercal


The Norwegians were already the leader in free opendata (API) but for forecasts it is incredible

What an amazing tool for so little money!  Connected to the Sigrok/Pulseview software and you have a very useful tool for decoding/troubleshooting.

I bought a expensive Saleae Logic 4, 7 years ago, which now gives trouble and need a warranty replacement.  But I won't need to send it back because now I have 8 channels instead of the previous 4 of the Saleae! Smile

For the curious:

I bought the aforementioned temperature + humidity "weather station" from Lidl for about 20 euros. As the supplied receiver reads remote data very seldom, I decided to see if I can make heads or tails of the data sent by the sensors.

Data is transmitted with 433 MHz RF signal in bursts which consist of 9 copies of data packets.
Data packets contain one sync pulse (~4500 useconds) + 36 bits (0 = ~1500 usec, 1 = ~2500 usec).
My Arduino code can reliably decode the data by checking for above pulse lengths ±50 usec, using either cheap MX-RX-5V or more expensive RXB6 receiver.
 
Code:
S rrrrrrrr b m id tttttttttttt ffff hhhhhhhh

    S  sync pulse (missing from the first packet)
0..7    r  random id (changes every reboot)
8    b  battery (1 = ok, 0 = low)
9    m  manual tx (1 if manual)
10..11    id numeric id 0..3 (only 0..2 used)
12..23    t  temperature (binary, 0.1 ℃)
24..27    f  filler bytes (1111)
28..35    h  humidity (binary)

I have yet to put a sensor in a freezer to see how negative temperatures are encoded (and whether the temperature really uses all 12 bits) Smile]]>

But now I got new interest for this topic because of the WeatherDuino system.  I have a wired Ultimeter2100 system but I would love to have a wireless  temp/hum sensor in my garden with the -yet to build- WeatherDuino setup.

I hope it's possible to upgrade the WeahterDuino system with Xbee or 868 Mhz communication but in the meantime I decided to learn about 433Mhz and related matters.

I came across very exciting and useful information and I am convinced this will be of interest to more of you:

Have fun!

I'm looking for help to get started. I have some experience with electronics and some with software but not an expert.
I have a Fine Offset weather station now that is a few years old, it works right now but I'm getting tired of the "loss of contact" I keep getting. I'm running Cumulus as well.

I understand I can purchase the working TX and RX boards from this site. I also understand that I could use the sensors from my existing Fine Offset weather station. Is this correct?
I guess I'd need some sort of enclosures for the TX and RX boards as well as power supplies, maybe batteries? Anything else I should plan for?

Anyway, any help would be appreciated.

Cheers,

I live in tower building and have problem with signal range, have two solution....

1 - use power booster, on ebay is possible buy around 20USD 5w out, but is non legal :Smile hehe

2 - use coax cable bettwen outdoors units and RX board in flat... In outdoor box will be splitter and DC supply, both over coax cable.... 


Both solutions are see in pics...

Next week make main boom for sensors and etc, post next pics...]]> I post here some photo from build my new WX... I live in tower building and have problem with signal range, have two solution....

For me, I will make 2 modifications:
1 / remove the mast.
2 / on the roof a channel to evacuate water from the rain gauge.
