I'm working on a vacuum pump product controlled with an Arduino or ESP32.
I have a working prototype but my motor seems to not reach the vacuum I need.
The requirement is that the motor uses 12V DC(or 6V) and is able to produce around 80kPa vacuum pressure in a 1L cylinder. I'm using the MPX5100 to sense the pressure.
I'm not an expert on pneumatics so I'm using generic pipes, silicone, and a 750mL bottle to test this. The motor I have is generic, so there's no datasheet that tells me the vacuum pressure it can create.
If someone can give any tips on how to create a proper seal between the motor/sensor/air valve/cylinder and how to choose the correct motor I would appreciate it a lot
