All changes only apply to the Urban Board/Code.
Added unit symbols
Changed the way the microphone records results, previously it gave a voltage reading eg 0.077. My hope is the current changes mean it now converts the voltage to dB and saves them to the logs in dB.

Our Enviro range of boards offer a wide array of environmental sensing and data logging functionality. They are designed to be setup in location for months at a time and take regular measurements.
On top of their individual features the boards all share a common set of functions:
- on-board Pico W with RP2040 MCU and WiFi functionality
- accurate real-time clock (RTC) to maintain the time between boots
- a collection of wake event triggers (user button, RTC, external trigger)
- battery power input suitable for 1.8-5.5V input (ideal for 2x or 3x alkaline/NiMH cells or a single cell LiPo)
- reset button for frictionless debugging
- user button to trigger wake events or enter provisioning mode
- activity and warn LEDs to show current status
- Qw/ST connector to allow you to customise your sensor suite
These common features mean that the modules can run off very little power for long periods of time. During sleep (when the RTC remains active) the boards only consume a few microamps of power meaning they can last for months on a small battery pack. The modules wake up at regular intervals (or on a fixed schedule) to take a reading, store it, and go back to sleep.
As well as logging data locally Enviro boards can also use the Pico W's wireless functionality to upload the data they capture to a supported endpoint. Wireless communications take a lot of power so this should be done as infrequently as possible.
