From Manuel Alejandro Iglesias Abbatemarco on Hackster.io:
About two years ago I purchase a home dehydrator, I was always willing to make my own dehydrated fruits, herbs and why not jerky too. After using it for a while I perceived that the device was very dumb, it took more effort than I was willing to do on a regular basics to dehydrate food, specially the thing cannot be leave working for long time without human intervention as t easily over dry or even burn the food. Sometimes I found that high content water food such as bananas or pine apple dry best with a high temperature for a couple of hours, then temperature should be settle lower for a long period of time. Many people on the internet have found better to dehydrate overnight, which makes the above situation not possible. Anyway last but not least because I am sort of nerd about taking things apart, I was anxious to modify my dehydrator to improve the whole process.
Arduino Fits Here Very Well
I start working with a little Arduino module, the Mini, it happen that there is an official Arduino Mini 05 which is ideally the one I should be using but the little thing is somehow difficult to find so I did my tests using Arduino Pro which is pin compatible module. This little Arduino is well suited for the project since it goes well in price compared to my $70 dehydrator, a more capable Arduino can speed up things but it was not going to be the right choice, basically because I was also hoping to make this solution available for public. I end up taking the difficult road, solving some problems the best way in favor of budget but with consideration to make the solution attractive to hobbyists as well as engineers out there.
