Dust Sensor - PMS 5003/6003/7003

Hi folks,

I have been using both SPS30 and PMS5003.

Here is a screenshot of the output.

The above values are using an ESP32 and not particle board, but I found this forum interesting so posting my doubts here.

My doubt is regarding the standard(CF = 1) vs environmental values from PMS5003. Till now I haven’t been able to find out the difference between these two. Could anyone guide me to some literature I can read about their differences?

Also, SPS30’s PM2.5 value is more close to PMS5003’s environmental PM2.5 value than it’s standard PM2.5 value. That makes me believe that environmental values are more useful than the standard values.

Please correct me if I am wrong.
