So, I'm designing a cooling system for a project I'm working on, and I'm a little stuck.
This is a phase change system, and I don't want to deal with trying to seal up my circuits to ward off condensation, so here is what I need to build, in psuedo-code:
Temp1 = Ambient Sensor
Temp2 = Component Sensor
IF Temp2 > Temp1 {
Key Relay On
}
ELSE IF Temp2 < Temp1 {
Key Relay Off
}
I would like to build this in a way where I can use a pot to adjust the relay on/off limits, so I can keep the temps just above dew point, to ensure that no condensation occurs.
I've been brainstorming a bit, thinking about possibly using two regulators feeding two thermistors and a comparator and transistor to turn the relay on and off, but I'm not quite sure if that will do what I want, and it would be hard to make it adjustable.
If there is a easier or better way, even without the temp ranges being adjustible, well, that's why I'm here.
