Weather station for ESP32 running Micropython

This is work-in-progress for a weather station built around an ESP32 running Micropython. The sensors are:

• bme680 temperature, humidity, pressure, VOC sensor
• sht31 temperature, humidity sensor
• si7021 temperature, humidity sensor
• PMS X003 particulate sensor
• Davis instruments tipping rain gauge
• Inspeed wind vane and anemometer

The weather station sends data to:

• MQTT (for local processing in node-red)
• CWOP (Citizen's Weather) via APRS
• Wunderground

This repository contain work-in-progress.

Source code

• This app requires micropython 1.12 or later, and most likely the version in https://github.com/tve/micropython/tree/tve
• The .py files in the top-level directory should be copied to the board's top-level. They are expected not to change over the lifetime of the board.
• The .py files in the src subdir contain the bulk of the weather station code and should be copied into a src subdir on the board. These files are expected to change (improve!) with releases of this repo.
• A lib dir also needs to be created on the board with specific libraries from my mpy-lib repo.
