Hi! I have been using one O-1PS and and an I-9PSL for around 2 years. They run the current Airgradient firmware with Airgradient cloud integration.
I’d love to know, how can I recognize if the sensors start failing?
Will I get any errors? Will there be missing values on the dashboard? Maybe I will just always get the same readings or will they just start showing absurd values?
Will the different sensors behave differently? (PM, CO2, NOx, TVOC)

Ps.
I did not have much issues with the devices and I couldn’t be more happy with Airgradients approach. I just would like to know when I need to replace some sensors.
Btw. I’m aware that the dust sensors life expectancy is approximately 3years, but they will probably last longer. However I did not find much info on the other sensors.
