Introduction
更多有关Dylos和BAM检测器的PM2.5与PM10读数的相关信息，请参考 Dylos 空气微粒计数器实验，第一部分.
If you want to know about other affordarable Air Quality Sensors such as Shinyei and Samyoung, check our sensor overview page.
Real-time data
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
因为农展馆监测站位于东三环路边，而Dylos监测站位于三里屯居住区内，为了确保农展馆提供的读数与三里屯Dylos监测站周围其他监测站的读数近似，下两幅图表显示了过去10天北京4个不同BAM监测站提供的PM2.5与PM10的读数。

DCDS Dongcheng Dongsi (东城东四), BAM PM2.5 in µg/m3
