My township has an Onset Computer HOBO station, which I have adopted and revived as a volunteer. It's a rugged system, designed for remote operation using solar power and cellular communication (3G). It's toward the higher end, but I don't know how it compares to a Dynacon. While the logging, transmitting and data integrity functions have worked flawlessly for us, I am not sure I'd recommend it, for the following reasons:
1. Requires a $150/year subscription to the Onset host site at HOBOlink.com. Someone has to budget for that bill every year.
2. There is no way to "calibrate" the sensor readings using numerical offsets to the raw data, as some less-expensive personal weather station systems can. Sensor replacement is the only option, and that's an expensive option.
3. How do you want to make your weather info available to the village and its inhabitants? With a HOBO system, there's your station's own HOBOlink webpage, and an option to feed data to the Weather Underground site. No other options, like CWOP and other websites, unless you want to try to program your own. You should think about this with any system you evaluate.
4. How current do you want the data to be, and how often do you expect it to update? With the sites mentioned above, the most recent readings are slow to show up on HOBOlink.com and therefore on wunderground.com too. A lot of time seems to pass before updates happen - up to a half-hour delay from real time is our norm, which I find unsatisfactory.
In short, great for gathering data, but not so great for public and timely presentation of the data. Weather Underground has been having its own set of issues too, over the last year or so. You can check my website link below.
