Hi,
I am somewhat of newbie when it comes to electronics. I'm looking at using an Arduino Mega 2560 to turn a furnace element on and off from the temperature it reaches, pretty much a PID.
Instead of me buying a PID I was wondering if I could make one with an Arduino?
I've been following the Bare Bones (PID) Coffee Controller :
and these are the schematics

The AD595 is a thermocouple amplifier seems simple to setup.
The SSR I'm going to be using is here
http://www.auberins.com/SSR%20Series-RS1A.pdf
It states it needs 3-32 volts to trigger; though reading the pdf it states "INPUT:Min. ON / OFF Voltage: ON< 4.25V"
also that it needs a current of 12mA.
The furnace elements are rated at 240 volts 15amps and YES SAFETY comes first!
(Starting this project I would test a simple thing like turning a light on and off first before wiring any elements.)
Questions:
-
I was wondering if the SSR I provided would be as simple enough to connect to the digital pin on the Arduino?
-
If I cannot connect the SSR to the Arduino, how could I get this setup to work?
Many thanks,
