History of 2007-08-02 Books Preservation

20:26 UTC Revision 1 . . . . 86.116-240-81.adsl-dyn.isp.belgacom.beThere are numerous [ enemies of books] : from fire to [ autodafé]. Another enemy is water or humidity... if your books start to smell moldy. That's not good a sign. A little bit worry about that, I installed a small sensor in one of my bookshelf. The purpose is to monitor humidity and see if the relative humidity level is going to the [ famous 75% limit]. I'm using an USB-based humidity and temperature sensor made by [ Raphaël Assénat]. The software and the hardware design is free software/hardware but you can purchase from him [ the assembled version] (maybe a good way to help the initiative). You can see on the today's graph that the humidity increased when it was very rainy outside and a window was opened. But nothing critical for the books. I'm just wondering when Ikea will include by default a humidity sensor in each [ Billy bookshelf] ?
