Holding a baseline pressure
Hello,
New here and I apologize if this is a dumb question but I am working with an air pump for the first time and had some questions. It is a simple DC diaphragm pump that works with a solenoid valve to create suction. The valve releases the pressure back to 0 between cycles. I am still in the early stages of exploration and I am just wondering if it is possible to control the solenoid with the PCB so that rather than letting the pressure fall to 0, instead falls to around 50mmHg and recloses.
Any other suggestions for holding a baseline pressure would be appreciated. Or just any resources or breadcrumbs for me to look into would be great too.
