Hi,
I'm working on a heat exchanger wich will cool down the wood stove gas temperature.
I think arduino is a good choice to control the fan power in function of the gas temperature.
I've never used arduino and I'm not good at programming (I'm studying mechanical engineer). That's the problem.
Can anyone help me on the project?
The gas temperature will be read using a thermocouple, then arduino will control the fan (30w 220V AC) trying to keep the temperature on a fixed value. I need a "progressive" control, not an on/off sistem.
Most AC fans use induction motors and cannot easily be speed-controlled. Look for a fan or blower (whether AC or DC) with a built-in speed controller and either 0-10VDC or (preferably) PWM speed control input.
I found the fun fitted on an other heat exchanger: the fun speed was controlled by turning a handle (manually).
Maybe I can use a step-motor moved by arduino to turn the handle in function of the gas temperature. It seems to be a silly way to regulate the speed... Or will it works?
