Re: Arduino and 1-wire based home built weather station.
Wired up the data logger shield with a DHT22, connection for the 1-wire and components for the exterior DHT22 connection plus the two LEDs. There's still the barometer module to add - when it comes.

Re: Arduino and 1-wire based home built weather station.
Now have a test sketch which is logging date/time, temperature, humidity and dew point. Here is the data in a spread sheet (Open Office Calc) taken from the SD card.

Your time stamps don't appear to be UTC. Potential problems when they jump back one hour in a few weeks time.Gina wrote:Now have a test sketch which is logging date/time, temperature, humidity and dew point. Here is the data in a spread sheet (Open Office Calc) taken from the SD card.

Re: Arduino and 1-wire based home built weather station.
Quite correct Jim - present times are BST. I have that to correct - I'm aware of it - but thank you for pointing it out I intend to set the clock to UTC (alias GMT) and leave it set to that. Conversion to local time can take place in the display software. That was a big problem with the FO station - insisted on using local time, causing big problems when the clocks were changed.

Re: Arduino and 1-wire based home built weather station.
Fixed the time - simply turned off "Daylight Saving Time" in Win 7 then ran clock setting sketch again. Then put Win 7 clock back to mormal. Added a "Z" to the date/time data to conform with the ISO standard for UTC).

Re: Arduino and 1-wire based home built weather station.
The barometer module came today and I've wired it up to the logger shield. Fits rather nicely

Re: Arduino and 1-wire based home built weather station.
Now have the barometer working and logging to SD file The module also reads temperature so I've included that too (called Temp2). However the temperature does not seem very accurate being a degree C or so high. The DHC22 is accurate to half a degree so I'll use that and ignore the BMP085 temperature.
Here are serial display and SD file contents.

Re: Arduino and 1-wire based home built weather station.
I'm now looking into accessing the 1-wire devices. The DS2423 (counter), DS2450 (4 line ADC) and DS2438 (battery sensor - voltage, current, temperature) are no problem - I've found and installed libraries for them but the DS2413 ( 2 channel switch) is a problem, I can't find any source of a library for this decice for the Arduino. I may have to change my circuitry unless anyone knows where I can find the DS2413 Arduino library.
The DS2413 is used to enable the LEDs used when reading the wind vane direction.

Re: Arduino and 1-wire based home built weather station.
As one wire devices go, http://datasheets.maximintegrated.com/en/ds/DS2413.pdf is pretty simple. You can take the existing library for another one wire device and just code up the two commands you need, based on example. It looks like all you need is reset, select, write a byte (F5 or 5A), read a byte, reset.

Thank you Yes, I was planning to do that when I get back onto this project - been very busy lately.ScottM wrote:As one wire devices go, http://datasheets.maximintegrated.com/en/ds/DS2413.pdf is pretty simple.

I need to get back to weather stations - even my FO station is out of action ATM - I think it's suffering from the weather!!! The unsupported mast has withstood the storms but I think the wire is broken.

Re: Arduino and 1-wire based home built weather station.
Hi Folks - I'm back And now working on this project again - trying to catch up on where I'd got to
One big difference - I now have a 3D printer and can print my own parts in ABS thermoplastic

Welcome back - what printer do you have? I've been thinking of getting one myself for making various bits. But mainly just for playing

Re: Arduino and 1-wire based home built weather station.
Thank you Steve and Mark
Steve - My working 3D printer is the UP! Plus 2 which is a small commercial unit with proprietry software and hardware. It's very good though more expensive than the more common RepRap based printers and kits. I was lucky to buy a secondhand one at under half the new price from Amazon. Nothing wrong with it and virtually new, just needed a bit of setting up. I use it an enormous amount for small plastic parts. The print volume is around 130mm cube. That compares with most of the RepRap printers of 200mm cube.
I am also working on a larger RepRap style printer. RepRap is an open source standard with loads of info available and using readily available standard parts. It is Arduino Mega 2560 based with shield for the stepper motors, heaters etc. I bought the Velleman kit but found it very unreliable and suffering from several design faults. So I've stripped it down and using the best parts and producing or buying extra bits to make it work better for both reliability and print volume.
