+# 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.
