They have all sorts of neat stuff (stepper motors and controllers, PROM progammers etc) I seem to recall they have standalone temp/humidity loggers and software.
Update: Had a moment to check, they do have temperature loggers. Prices vary but for the budget conscious amonst us (all of us
), there is this model.
