I am totally new to this. I have a Arduino Mega 2560 and I would like to perform long-term observations of PM (2,5 and 10), Ozone and NO2 (for around a year, outdoors).
Do you have any ideas which sensors might be suitable for this? I have a few sensors in mind (for PM: SDS011, Plantower PMS 5003/7003, Sharp GP2Y1010AU0F, Honeywell HPM Series...) but since this is my first time doing this kind of stuff, I dont have any experience. Do you mind sharing your experiences with me? I would be happy for any help!
