Hi Tom, That means a Baby Grill Device !!!, I am thinking in safety first. Maybe two controllers working in parallel with a third one checking each others will do the work well. I am planning to use PC100 thermocouples ( there are very sensitive and fast ), heath source must have an external cut off sensor/switch to avoid overheath. The thing is to send via RS232 any change in temperature, humidity, air flow and maybe the beat rate of the baby4s heart to a remote workstation.
