**DIY electronic pressure meter**

Measure the pressure in beer bottles during the carbonation stage. Periodicly
send the data to a MQTT server for further processing.
It has a little OLED display and rotary switch to control the unit and view

temperature sensor. The devices runs on a USB charge adapter.

The generated MQTT data fits the BMS server.
