My Weather Station in Progress…<\/figcaption><\/figure>\n\n\n\n

For all of you that might be a little bit of a “Weather Geek” like me, and care about your respiratory health, here is a project that may be of interest to you, especially with regard to environmental exposures monitoring, along with a standard local weather station. I have put together this project that you can build for yourself, and it can be expanded to measure other aspects of your local environmental\/weather conditions as well. I have listed this project on Thingiverse (https:\/\/www.thingiverse.com\/thing:7347425<\/a>), and plan to put up a Github<\/a> repository for the code, as well as an Instructables<\/a> page to provide instructions for the build process.<\/p>\n\n\n\n

*Everything here is a “Work In Progress”, so just know that things will change with regard to this project over time. At the end of this post, I will attach a BOM for those who wish to attempt this project.*<\/p>\n\n\n\n

It is a Raspberry Pi Zero 2W<\/a>\/Raspberry Pico 2W<\/a> based wireless indoor\/outdoor environmental conditions station that happens to also function as a local weather station. For this project, I chose to use a Raspberry Pi Zero 2W<\/a> for the main server “base” station, and 2 Raspberry Pico 2W’<\/a>s for the “remote” devices, to take the following measurements:<\/p>\n\n\n\n

    \n
  1. Outdoor Weather (With UV Index)<\/li>\n\n\n\n
  2. Outdoor Air Quality (Particulate Matter)<\/li>\n\n\n\n
  3. Indoor Air Quality (CO\u00b2 Concentration)<\/li>\n<\/ol>\n\n\n\n

    The Raspberry Pi Zero 2W<\/a> will function as the central server to receive and report the measurements of the 2 Raspberry Pico 2W<\/a> sensor devices, and render the data it receives from them in the WeeWX<\/a> webserver interface that you can access from your web browser on your computer, smartphone, or tablet on your local area network<\/a>. It has has the following software installed:<\/p>\n\n\n\n
