I am gonna build two identical boxes for testing two different house insulation products in the harsh weather conditions where I live. The plan is to put two (hopefully) identical heat blowers in the box and a relay to start and stop the fans, so the temperature is kept at 70* F, with a certain hysteresis.
At the end of the experiment I am comparing watts used over the course of a week, or so. For this I am going just to plug the fans in two identical watt meters.
I have a Microchip HPC, that I would like to hook up to the temperature sensors inside, but I need to switch the 220V fans on and off with the help of the HPC, so I need relays for this.
Could you guys recommend me some parts for this little project? Always when I start something, I usually get stuck, because I have no idea what to use, and the delivery time to where I live is...not fast.
