From the little I understand about a PID set up is that it can be pre-programmed to monitor and stabilise a temperature using an SSR.
Looking back through old threads, this Sestos controller seems good.
but can i add an hygrometer such as this that would enable the PID to turn on / off a dehumidifier?
or do i have to bite the bullet and buy this and build a separate PID for the mash tun
I would keep the controllers seperate.
A PID will pulse the power, in ms, to get a smooth temp change. Great for a heating element, would stuff a fridge. The sestos will allow you to change back to on-off mode for fridge mode, but it would be a bugger forgetting to change it and killing your fridge. Another thing is the compressor delay, for a fridge you want a couple of minutes, for brewing you want it off, more crap to have to change. Also what happens when brewing runs late, and you forget to put the pid controller back on the fridge? No so good for than pancetta/etc that you have spent time and money on.
For the curing chamber:
I've never seen/used that pre-build dual controller but I think I would go with it. Looks pretty neat. I used a standard stc temp controller and ebay humidity controller for mine. For creating the humidity I used a ebay pond fogger, works great. Just make sure the one you pick includes the power supply.
For the brewery:
The stc will actually do a decent job, but a pid (such as sestos) will help smooth out the over and under shooting. A lot of the sestos packs are sold with really crappy temp probes, so consider buying a better one separately.
