Re: Silicone Grease? corroded PCB
Hi, I have my Watson sensors mounted very close to the sea (2m at high springs) and have found that the PCB inside the transmitter has corroded and failed after five years. I have always kept the plugs covered in silicone grease or vaseline to protect them, which has worked fine, but was thinking I...

Re: Weather Station Sensors
This photo is out of date but gives the general idea. http://ginad.org.uk/weathergd/images/Outdoor_Sensors_med.jpg This photo shows the wind sensors at the top of a 20ft mast with the temperature/humidity sensor and transmitter unit on a shorter post about 5ft high with my own Stevenson screen. The ...

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 ...

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 temperat...

Re: Fine Offset anemometer repair
Yes, I guess that's the only way to be sure of your calibration.

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: Fine Offset anemometer repair
Yes, I think the wind speed readings are definitely on the low side - my measured speed always seems lower than the Met Office reported values for this area. There is a reporting station just a few miles away on a similar height hill.

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.
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 statio...

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.

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 I'm looking at the sensors - how many and which pins they require. Everything 1-wire goes on one single digital pin, which takes care of wind speed & direction, light level and rain gauge. Temperature/humidity will use the DHT22 and one pin but for both indoor and outdoor, that's two. Gina,...
