Vaisala has a couple of temperature and humidity data loggers, HMT-140 and Veriteq SP 2000<http://www.vaisala.com/en/products/dataloggers/temperaturehumidity/Pages/default.aspx>, that also seem to be viable options.  They are even marketed for cleanrooms.  I haven't used either of these two units, but I have used their PTU300, which also logs barometric pressure.  At a previous semiconductor facility, our wet oxidation process control went berserk every time a storm came through.  I installed one of the PTU300 units and dynamically adjusted oxidation times to compensate for barometric pressure.  It was quite helpful.  I've been gone from that site for several years now and they still use it.

Dear Colleagues, We are closing in on starting up a new class 1,000/100 facility here at UCR and I am looking for a low cost solution for remote monitoring of room conditions for the 2 new clean bays. Has anyone used a standalone monitoring system for humidity and temperature that connects to Ethernet with software that would allow remote monitoring? Our budget did not allow for a sophisticated well integrated solution like the Johnson Controls system we have in our first cleanroom, but I still need to know the conditions of the new rooms from my remote office.
Any recommendations or experiences good or bad would be appreciated.

Regards,
