Hookup OLED I2C display to temorary display some data.
# CO2 Meter Measure the pressure in a beer bottle during the carbonation stage. Periodicly send the data to a MQTT server for further processing. It has a little OLED display to view the current measured values. It should be fitted with several pressure sensors and run on a battery. Therefore it should use deep sleep and other techniques to save battery life. Also, some touch keys to do some stuff like wakeup the display. The MQTT data should fit the BMS server.
