My first guess here is that you would have to use a PLC or a microcontroller in this case (for example Arduino). Are you familiar with these?
Both would be the “brain” of your application (you would have to program it), although PLC is more durable and expensive since it is used in industrial environment and Arduino is cheaper and easy to use.
Yes. Good project. Been using solar power to run 3 ceiling fans, 2 led grow light strips and 2 exhaust fans on a timer for a 43x12 greenhouse on the Oregon coast.
Not familiar at all with the acronym PLC or arduino other than I’ve seen it spoken snooping around.
I’m also hoping to expand to automate a watering system with a few 12v bilge pumps for some auquaponics later from an outside fish pond to circulate poopy fish water through the plant roots to feed the plants and filter the clean water back to the pond.
It has a built in limit switch if that helps to not over complicate things.
I’m just looking to use a thermostat and or a timer or something to do what the remote and transmitter/receiver does. Send a current till it hits the switch to open up, then reverse polarity to close down till it hits the other switch.
The video from @tepalia02 is what I initially had in mind. Video shows nicely how to control actuator from Arduino. In your case, you would connect sensors (temperature sensor) to Arduino. Then, you can program it to open/close doors based on timing and/or outside temperature.
Doors need to always override timer and open if it ever gets above 85F then close at or below 70F or so unless timer is active. Will only open all day for 9 months of the year but closed during the day in the winter unless the temp gets over 85F which can happen on sunny days.
