Assuming that you have a Raspberry Pi or other system with the database and Apache software:
If you want to monitor temperatures, all you need is a TeensyNet board, and some DS18b20 cables, or one or more of the thermocouple boards for a greater temperature range.
If you want to control temperatures, adding an action board to the above allows you to connect two SSR's to control the AC to your fermentation chamber, keezer, etc.
If you want a local display, one in addition to the web display, then use one of the display options.[/QUO
Since I've mentioned previously that I want to use this to control fermentation temps, are you talking about the MAX31850 Action Board when you talk about adding an action board? Also some DS18b20 cables....anything else? Any ideas on how to do the software end of this venture surely appreciated.....thanks again
