Overview

What is PMPCTRL?

PMPCTRL is a little system that gives you precise control over vacuum levels. It uses a pressure sensor, an electric vacuum pump, and a valve — all managed by custom software running on a Raspberry Pi.

You get a clean web-based interface that lets you monitor and adjust everything from your phone or laptop over WiFi. No apps to install — just open a browser and you're in control.

How-to Build Your Own

Building PMPCTRL is a rewarding DIY project, but it does require some hands-on skills and basic tools. If you're comfortable tinkering, you'll end up with a solid, custom vacuum controller.
