Welcome to PressureMon

Note

This documentation reflects v0.6.0 - development. Last updated 2025-06-08

What is PressureMon?

PressuremonMon is a IOT device that can measure and measure pressure and temperature during fermentation or storage of beer and transmit the data to a number of external services. Is uses a digital or analog pressure sensor to measure the pressure.

The analog sensor version require a separate ADC chip to have the needed accuracy. This option is still work in progress.

The github repository can be found here; PressureMon on Github,

User Interface is stored in this repositiory; PressureMon-UI on Github, where the documentation and builds are stored. The sensor specific code is also stored here for easier testing and development.

Note

I don’t take responsibility for any errors or issues caused by the software or hardware. The software is provided as-is. I will however try my best to fix issues that might occur.
