Working on a refridgerator running on an off-grid solar system and wanted to come up with way to add internal air circulation is a top priority. This is a project to make the entire home run on solar batteries daily.
The goal is to have the arduino seperately control the relays when ever the main modules are in need of tuning. This particular approach is a precursor. As to use the same relay setup for the skylight tied into ventilating and in reverse also circulate fresh air.
Any insight would be much appreciated. The relays represent the "Electronic-Salon relay module which has dual inputs with max of 250v/5a. The fridge previously ran off a temperature control module from amazon. Which was tied in with a DC to AC solid state relay with a 40a rating.
This schematic allows the option to take the same wiring and input modules to then be able to allow learning on DIY levels of creating other arduino smart home applications such as Hepa Filtration Cycling, Ozone sanitation use with regard to safety limits when entwined with air quality control and safety as well. Its a big personal project. Hoping posting here really gets the ball rolling.
The Shelly Pro 4 Pm will be a major factor into having a sturdy power control factor as well as the Z-Uno module.
That part of the project aspect listed is complete and applied to the physical relays. Just waiting to test it with different brands of thermostats etc. I will make a mock up diagram the testing is completely put together.
The whole project is moving forward. Ill upload pictures in an hour or two.
The Relay simulation works. I have a working model. The voltage how ever cannot be achieved with 12v/5A power supply and instead needs to be powered with the 12v/5A power supply as a whole with and applied with switches that give a power supply currently with a 10 amp fuse.
Everything has been broke down into small tasks. My first diagram of the solar power system freezes and crashed my little computer pad. So it will take time to adjust from 5k-10k sized diagrams to something much less.
Currently contemplating duplicating this relay to function as a /switched/bypass-switch during auto mode/optional module input/optional module controller #2. Which is a god index of a controller allowing the smart home function to be bypasses for safety measures such as ventilation or adjusting pressure in certain areas.
