Hi all, I’m very good in mechanics but electronic controls is relative new for me.
My project is to control a distillery; temperature is the most important part.
I would need 4 sensors and 4 relays. All works at the moment with PID controllers.
My first question is the hardware, what should I buy to get started?
What board, sensors (50 to 120 C) and relays would you suggest?
A WIFI warning system and control would be a nice add, also an Iphone app which shows the temps over wireless would be great.
I’m not afraid of time or cost to have it done, it’s a hobby challenge for me.
I searched before to see if it has been done before but couldn’t find anything.
Thanks for any help and suggestions.

Start with a description of why that needs to change.

Any Arduino will work. The relays depend on the voltage and amperage being controlled. Perhaps I missed that part...
Hi Paul
It's not that it have to be changed, as I said, I see this as a challange to understand the Ardino concept.
I like the possibility to have a WIFI control which the PIDs don't have, also expansion for other tasks is in the view.
I also own a BCS-460 which is HTML based and can be connected to an AP for wireless control.
Just wanna know what is best for my needs in the future.
The relays would control 12V gas and water solenoids with low AMPs.
So I would be fine to start with a Ardunio ONE, right?

If you can find one. If not, a UNO would be good.
Haha, good one, my fault.
UNO is ONE in spanish, I talk German, Spanish and English, sometimes getting confused.
Hello StillSmith!
I currently have a 1800w glue heating system setup with 3 separate temperature controls on an Arduino Mega.
I am using 3 LM50 SOT-23 temperature sensors and Opto 22 Z-series 10amp relays. I do not know if these are the best, but they work for me (in hindsight, the temp sensors are a little hard to install because they are so small).
I am using Brett Beauregard's PID library (Arduino Playground - PIDLibrary) and timer3 configured to a one-second PWM rate.
