Build a Pluse Propotional stat

Hi everyone,

Im new to this forum and i have a project i am looking to do which is to manage as well as display the temperatures 7+ vivariums containing various reptiles.

The reading and displaying the temps should be fine for me, but here is the snag.

I have become very fond of the microclimate/habistat pulse propotianal thermostats. and i was wondering (with the right additional components) if the arduino could act as a hub of stats instead of having 7 seperate stat units?

Any one got any ideas if it is possible/been done?

Pulse stat is mentioned here: http://www.chrismartinservices.co.uk/downloads/pdf_info_thermostats.pdf in-case you are not sure what i mean.

Welcome.
Yes, but not wishing to put a downer on your enthusiasm, have you considered that if one of your stats fail, you only lose 1/7th of your collection?

This has been considered. I am planning safeguards etc... but i was wondering if/how it can be done.

Solid state relays (SSRs) and some Dallas single wire temperature sensors or similar.
Probably double-up on everything, for redundancy, maybe even triple-up, with a majority voting scheme.
Yes, do-able, but make sure you test thoroughly before going "live" ("live", "vivarium", geddit?)
Just out of interest, how much do the current stats cost each?

1 unit. you talking up to £59.99 GBP
