I have a space heater with a thermostat built in, but it is terrible. It has a huge deadband and will click on and off enough to trip itself on occasion. So I’m building my own. It will PWM with the SSR and will have and external temperature sensor. An Arduino will run the whole thing.

Its our local variant of a pizza-oven reflow controller, does pretty much what you summarized in the article :)
Cheers!
Thanks man! We’ll do our own reflow oven one of these days. This might come in handy then! For the space heater I’ll definitely want a PID loop since I’ll be heating a large space relative to the space in a reflow oven.
