Forum,
First off.. I have used the search. I know there are several threads about reading temperature but, I found nothing in the range I need.
Reading Temp.
I maybe using RTD with 10mv/degree F change. Do I need anything between the RTD and a A/D converter?
Controlling 500W 120V heater. Can I PWM a triac to control the output?
The accuracy/resolution is not high. +/- 25 degrees.
This would be a side function and can not require a lot of processing time.
Does anyone know of a existing solution for this type of control that could be controlled by 8051 but works on its own after the temperature is set?
Thanks for your support.
