Hello,
I'm trying to build an Incubator.
The goal is to control the temperature inside the incubator threw Arduino.
My heating elements are resistors that connected to 230VAC.
The idle needed temperature is 37.5C stable!
It can variate up and down something like 0.2C, for getting the best hatching results (better accuracy better hatching results).
BTW i'm using the DS18B20, i know that it's not as accurate as needed but i got external thermometer with 0.1C accuracy that would help me to calibrate the temp.
With that part i'm quite doing okay for now.
The other part of the project is the tricky part for me, using parts that handling the high voltage.
After searching and checking a lot of the information on the web i'm finally ended with this circuit: http://i.imgur.com/QsFVxFe.jpg
(sorry for the hand written circuit).
The thing is that those kind of circuits come in many different ways with slightly changes from one circuit to another, including the values of the resistors too.
I would be glad if you will check my circuit, the components and the values of the resistors considering the right currents and voltages that are needed to make this circuit work.
If it's okay i will purchase the components and continue with the project, if not i will make the needed changes of course.
Waiting for your help.
Thank you in advance.
