First post so if I am wrong just let me know.
Here is what happened, we have a proofing cabinet and electronic board is dead, the manufacterer of course does not want to give any data or wiring diagram to fix it, he just wants to change the dead computer board for a little fortune. For now we just pulled ou the dead board and placed a temperature controler and a humidity controler to be able to use it.
First project making a new board with arduino hope it is possible. So it has to be able to deal with....
2 input one for the temperature sensor and one for the humidity sensor
Must be able to adust temp and humidity
Must be able to show actual temp and humidity
Has to control relays for the heating, compresseur and fans (there is 2 fans one for the heating and one for the cooling)
Has to control the relay for the steam maker
Same as above but must be able to be programmed for cooling and a set time for dough ready like at 6AM for cooking, arduino will have to calculate what time overnight to sart the heating slowly and increasing temperature on a regular basis.
What is needed ???
Which arduino model (so many different)
which temperature sensor
which humidity sensor
which lcd display
which button switch
which relay card
real time clock (RTC)
where to buy
and all what I have forgot
Thank you for reading and helping the best you can
