Introduction
For more information about those real-time dylos and BAM monitor PM2.5 and PM10 readings, please refer to our article on the Dylos Air Particule Counter experimentation.
If you want to know about other affordarable Air Quality Sensors such as Shinyei and Samyoung, check our sensor overview page.
即時數據
Current dylos readings are: Particules larger than 0.5 is -, larger than 2.5 is -, updated on - - (China time).
Those values are expressed in number of particules per 0.01 cubic foot (100.n/ft3), i.e. same as what is displayed on the Dylos LCD.
Time series graphs
Note that the comparison between Dylos and BAM readings is done for Dylos ≥ 0.5u with PM2.5 and Dylos ≥ 2.5u with PM10. You might think that comparing readings for Dylos ≥ 2.5u and PM2.5 might be more relevant, but this is actually not the case. The explanation is given in the experiment ' what is the dylos monitor actually measuring'.
Variation between stations
The next 2 graphics show the PM2.5 and PM10 raw values (in µg/m3) for different BAM stations (i.e. without the Dylos values) in Beijing, for the last 10 days. This is provided to ensure that there is not significant devitation between the various stations, especially considering that some are located on the road side, while others are in the living area.
