The SDS 021 Sensor is the latest update from inovafitness on their SDS Air Quality sensor range (the first one in the SDS011. There is also an intermediate one called SDS018 which we did not review). 2 SDS 021 sensors are collocated. The objective is to understand the accuracy of individual sensor readings, and potential level of error induced by the lack of efficient calibration of low-cost sensors . To be udpated later
Spec sheet: SDS021 传感器 Note that the time-series graphs are showing the values using AQI (and not raw mg/m3). The AQI is based on the US EPA breakpoints. For PM1, the PM2.5 breakpoints are used.
Meteorological conditions, and especially the Relative Humidity (RH) is needed as high RH might have a direct impact on the size of the particle size detected by the laser. For BAM sensors, there is actually a requirement for constant humidity.
