The sensor I used was one of these (https://www.amazon.com/gp/product/B07NSGY7B3) attached to a ESP32 sending data to my grafana/prom setup on my nas. If you have done those it's like 2 hours of work and about $40 per sensor/esp pair. I couldn't leave the house without a respirator when our aqi got up to 650 for 2 days. Anyway it's pretty easy to play around with. I didn't save the data anywhere unfortunately. |
