[JT118]

After some reasonable rainfall on different days two weeks ago, I yielded poor results on my sensor. It was mostly 50% behind my manual rain gauge. The manual gauge was spot on each time with another station located further up my street.

I have just taken delivery of a replacement sensor, this time bought from another supplier. The thing that stands out with the new one when I opened the funnel, is that the magnet protrudes out of its holder in the buckets, and is positioned very close to the reed switch chamber. On the previous one, the magnet is molded into the buckets, and not positioned so close to the reed chamber. The magnet is not even visible.

I have changed them over, and will now await some precipitation for the first test. We are forecast for possible showers later in the week.

I have one of these which I intend to hook up to the weatherduino.

(I hasten to add I did not pay that kind of money; got it off ebay for a fraction of the price, some old research project selling up)
I have to say that I think the accuracy of the FO gauges is fairly "ordinary" compared to a davis gauge and certainly compared to the Texas instrument. The "sharpness" of the tipping bucket top will determine the accuracy of the gauge at the critical cusp. Additionally, I am not sure if the FO gauge can be adjusted and therefore calibrated even at the fairly basic "field" level described above.

Eventually I intend to put the weatherduino on my website and run both the davis system and weatherduino simultaneously on separate page and do a comparison. www.ayrshireweather.org

I have got some very nice anemometers, again research grade, old(1990's) but beautifully made which will also go on the weatherduino once I have sorted out how they can be read. See thread ( http://www.meteocercal.info/forum/Thread...nemometers )
