I’m converting a simple cooking hot plate to have it’s temperature controlled by an arduino, with an lcd.
It’s metallic casing gets really hot when the plate is turned on.
As I’ll remove the original analog temperature control and use an arduino and thermocouples to control the heat, even I I had space under the heat element, I think it would toast the electronics pcbs and lcd.
So I’m thinking of using an external enclosure to put the arduino, lcd, rotary dial and sensors connections.
But I want to keep this enclosure attached to the metal frame of the cooking hot plate, not hanging around with cables.
Is there a material to isolate the heat from the metal case from the hot plate to an external attached enclosure, so the circuitry will be in an “acceptable” temperature? Something to be put between the metal frame and the enclosure? Silicone rubber?
I don’t have the enclosure yet. A plastic one would be easier to make holes, but it can be an aluminum one also.
