I'm looking to set up temperature/relative humidity data loggers in tropical rain forests and was wondering if anyone knew of the best data loggers to use out of Hobos (http://www.onsetcomp.com/), LogTags (http://www.microdaq.com/logtag/haxo-8.php) and iButtons (http://www.talk1wire.com/DS1923-F5--Hygrochron-Temperature-Humidity-iButton_p_101.html).
I know Hobos have been used in field studies in the tropics but they are much more expensive than LogTags and iButtons. The benefit of Hobos is that the battery can be changed whereas with LogTags and iButtons, once the battery dies, they're useless. Has anyone tried these data loggers in a tropical setting that can recommend the best option? thanks, Carrie
