I am working on a project and have been delving into electronics. I am still quite new, however, so I would love to hear any info/advice you have!
I would like to heat incoming air through a short pipe to a certain temperature. This would be heating up air from inside (60°-75°) to no more than 80°F so a 20°F increase at most. Power would come from a 12V source, and be regulated by a microcontroller.
I am looking at ways to create this heat, and would love to get some advise. Would a typical (large) carbon resistor do the trick? I have looked at getting some Nichrome wire, but that may be overkill for the small amount of heat I want to dissapate.
Your answers (and more questions) made me realize I am missing some info to calculate this. In particular I will need the air volume flow rate before getting numbers.
I think I will try a few different options and find the best one experimentally. Thank you all for your help!
