Volcano_498	0:b30f86a9a1c5	3	@brief Code for a Portable Weather Station to be built on PCB.
Volcano_498	0:b30f86a9a1c5	4	@brief Design Specs: *A small, portable battery-powered data logger that records sensor data at regular intervals.
Volcano_498	0:b30f86a9a1c5	5	@brief -- Minimises mbed power consumption to the greatest extent possible.
Volcano_498	0:b30f86a9a1c5	6	@brief -- Displays the information to the user.
Volcano_498	0:b30f86a9a1c5	7	@brief -- Features a BMP180 pressure and temperature sensor. (TMP102 is unnecessary as BMP180 also takes temp. readings)
Volcano_498	3:70e14f1577f7	8	@brief -- Features a Nokia 5110 display to print the sensor readings over and display them to the user.
Volcano_498	0:b30f86a9a1c5	9	@brief -- Sensor information is recorded on Flash memory on the mbed.
Volcano_498	0:b30f86a9a1c5	10	@brief -- Graph to display data to the user.
Volcano_498	0:b30f86a9a1c5	11	@brief -- mbed is powered by a Buck regulator (5V output) that is in turn supplied by a 9V PP3 battery which powers the PCB.
Volcano_498	0:b30f86a9a1c5	12	@brief -- Audible and visual alert when a threshold reading is obtained.
Volcano_498	0:b30f86a9a1c5	13	@brief -- Celsius-to-Fahrenheit and Celsius-to-Kelvin conversions of temperature readings and displaying them.
Volcano_498	0:b30f86a9a1c5	14	@brief -- Adjusting the unit the pressure is displayed in: millibars(mb), Pascals(Pa) and Atmospheres (atm).
Volcano_498	0:b30f86a9a1c5	15	@brief -- Displaying a brief splash screen to show changes in the unit display settings.
