I want to regulate the temperature in a cure rooom to 21*c to 25*c. The room is essentially a walk-in freezer with no controls. The room need to be at 95% Relative humidity by the use of misting heads. The water temperature going thru these heads is what keeps the room at the right temperature.
I found a product to do this but is pricey at $2000.
It is essentially a mixing valve tied to an actuator that turns more or less hot/cold water on based on the needed temperature and a feedback temperature.
Here is an example: http://www.qcqa.com/product/product.asp?prodPID=831
I assume this would work by measuring the room temperature and if it falls below 21* then the picaxe would roate the valve/actuator via a motor so more hot water gets in.
I have not yet worked with servo motors but would this be the type of motor for an rotary actuator? At first this seems like a simple task for the picaxe. Any thoughs on how this program would work?
