For most of us, the purpose of PM2.5 and PM10.0 readings is to calculate the corresponding AQI, which usually is done based on averaging the measurements for 1H, 3H, 12H or 24 hours.
Each picture represents the last 24 hours (not last day).
Both dust sensors are read in sync (max. 1 second difference) at 10 minutes intervals.
Unit 1
Data measured with an WeatherDuino - Air Quality Monitor
Unit 2
Data measured with an WeatherDuino - Air Quality Monitor
Prepositionally, I am not identifying which sensors each unit uses. One uses Sensirion SPS30 and Sensirion SCD30, and the other PMS7003 and MH-Z19, for dust and CO2 respectively.
I know its hard to discover which one is which one!
Bets accepted!
During the upcoming week, I will try to publish similar pictures for other 24 hours periods.
I'm also preparing on ThingSpeak a live comparison with data from the last 12 hours of readings (PM2.5 & PM10.0, as also CO2).
