I mentioned it in previous posts. We have easy to use open hardware and software build instructions [1] for an air quality monitor based on a Wemos D1 mini. More than happy to help anybody who wants to build one. I have some PCBs left and can sent them to you (will only charge the postage). Feel free to contact me if you interested.

That looks fun. if its your site the 'Plantower PMS5003 PM Sensor' link says it can't be shipped to the USA, presumably there are other vendors on aliexpress who do.

That's awesome! I run a little community monitor for my little community in Gary, IN. https://millerbeach.community https://millerbeach.community. I track PM2.5/10 with a PurpleAir, but want to start tracking other pollutants/gases/VOCs, but there is no consumer-grade equipment, and I wish I could afford the $5k purchase + $1-3000 per year rental of the scientific-grade equipment from Ambilabs, EarthSense, or Kunak. I see this is PM2.5 + CO, is it possible to add other sensors to it, too?

  Yes. The pcb board actually has through holes to connect other sensors to unused IOs and you can easily adjust the software because it is open source.

This is great! Thanks for the hard work. How can I contact you for the PCBs?
- ahaucnx 6y ago
  The is a contact us button on the website. Just use that.

Awesome project thanks! I did a dual indoor/outdoor homebrew weather/air quality sensor at the beginning of last summer. Very useful during the smoke season. Wayy less polished though! https://partofthething.com/thoughts/weather-and-air-quality-monitoring-station-with-esp8266-and-home-assistant/ https://partofthething.com/thoughts/weather-and-air-quality-...

  Very nice project! I have a question on the light and sound sensor you use. Are these able to output calibrated values eg in Lux and dB?

    Well I get the raw data in a ESP8266 at which point I could certainly transform it using various calibration curves on the way to the (Home Assistant-based) dashboard.
