Electronic control for RV positive air pressure system.. Answered
I am biulding a positive air pressure system for my RV. I would like to include an electronic control system that will allow equal pressure inside and out or positive oressure inside. This will NOT allow any dust to enter the vehicle.
I was thinking using an altimeter/pressure sensor for measuring internal and external air pressures. My concern is that the outside air flow while travelling will create a negative pressure reading.
I also require circuit diagram for sensors cuopled to a 12v air blower.
I look forward to comments and ideas.
