Review: Airly PM + Gas – See The Air

Oct 26, 2020 · Regarding the NO2 and O3 gas sensors, I was able to measure events of high NO2 during peak hours in the morning and afternoon. In the morning, when people go to work, I always get a spike of ~55µg/m³, which has created a pattern hard not to acknowledge. The ozone sensor registers high concentrations of the gas at 15:00 with values reaching ...

Differentiating NO2 and O3 at Low Cost Air Quality ...

In contrast, an unfiltered sensor senses both gases with a defined sensitivity for each gas. We find that the use of a pair of sensors, with one of the sensors filtered and one unfiltered, allows the quantification of both O3 and NO2. However, the MnO2 filter confers some indirect NO cross-sensitivity to the filtered sensors.

Apr 14, 2021 · If you are working with the O3/NO2 sensors your working might be 2.900 V (out of 3.3), and you need -25 mV bias. Therefore, your reference voltage needs to be 2.925 V. Bias voltage is working voltage minus reference voltage. Similar to step 2 determine the values for the resistor ladder that give you the highest stability, but the lowest current.
