Carrie,
I've used the LogTag recorders in the understory of lowland Caribbean tropical
forest - La Selva Biological Station and other sites in Costa Rica and
Nicaragua. I've been very happy with them. I initially tested their accuracy
by running two data loggers next to each other for a period of 4 days. The
temperature and relative humidity estimates were nearly identical, with mean
differences of <1%RH or 0.5 degrees C. Most recorders lasted approximately 3-4
months of regular use, with a minimum of ~2 months and a maximum of 6-7.
Cheers,
Nicole Michel

Subject: [ECOLOG-L] data loggers in tropical forests
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
