Hello there,
I purchased a grove-dust sensor- “PPD42NS” and I will be receiving it soon. I would like to calibrate it against a research-grade optical counter, but I am not sure about the calibration setup. So, I request you to let me know if there is a standard or mostly used procedure to do this calibration (also please provide me with details regarding the devices that are available on the market, that needs to be used for this calibration)
Thanks and regards
Vineeth R
@vineeth_2808 According to this specification, this does not require calibration.Are you running into a bias now?
