Heating Element Control

Hi Everyone !

I'm looking for a simple and not too expensive solution for controlling a 2000w immersion heating element.

Ideally, in a first step, the element should quickly heat at full power until reaching the required temp. Then, it should regulate itself to keep the same temperature read by the temp sensor.

  • Do I need anything else than an Duemilanove, an LCD screen
    and a temp sensor?
  • Does such code already exist?
  • If not, what would be your guidelines?

Thanks a lot in advance !

In addition you will need an output to control the heating element. A solid state relay is the most likely solution.
Also a few user controls to adjust the desired temperature and control mode.

  • Does such code already exist?
    There is a general purpose PID library in the Arduino playground that is the typical solution for temperature control.

  • If not, what would be your guidelines?

Thanks a lot for the answer !

What relay would you advise me to get? :slight_smile:
