The quick answer is that it depends, of course! It depends on what
information you want, what you want the data logging to tell you. You may
need 1 logger or 12 loggers, or even more. If you are having a moisture
problem in the room, and want to try and locate the source and any
micro-climates created by it, you need a number of loggers. If you want to
show staff or trustees the effect of stratification of the environment at
various locations and heights in the room, you need a number of loggers.
If the room is divided into smaller rooms, you need a number of loggers.
If you have cases, particularly large ones, that create micro-climates, you need
a number of loggers. If you have a single room with no known
problems in which you want to have a general idea of the environmental
conditions, one logger in a central location at the height from the floor that
reflects an average for the collections in the room will be fine. Just
remember that T and RH conditions will be different closer to walls, lower or
higher, and in any areas of heat, including sunlight. This is true for ALL
rooms, not just yours. And for general preventive preservation of
collections, you don't need really expensive data loggers. Hobo U10
loggers will do just fine.
Good luck!
