Figure 3

Correlation of the concentration of PM2.5 in μg/m3 reported by different PM sensor models. Graphs show reported PM2.5 concentrations from Plantower PMS7003 (n = 5,906,616), Plantower PMS5003 (n = 5,523,274), Alphasense OPC-N2 (n = 4,420,042) and Honeywell HPMA115S0 (n = 946,372), with the data combined from each model at each location of the study except for Honeywell HPMA115S0 (only one location available). The x-axis corresponds to the sensor named above the graph and the y-axis correspond to the sensor named to the right of the graph. The upper 0.0001% of the datapoints are not displayed. Slope is reported ±2 standard error (***p < 2 × 10−16).
