hello,
i have the AS7265X sensor and i need to study the reflectance of leaves.
i’m measuring using artificial light and using this configuration:
AS7265X_GAIN_1X
AS7265X_MEASUREMENT_MODE_6CHAN_ONE_SHOT
integration cycles: 255
at the moment i’m getting only raw data, but i think i need a calibration according to my source light.
do you have any idea how to do a calibration?i have a blank teflon disk for the c alibration, should i use it?
You’d block all ambient light and set the light to a known distance & power and run an edited version of this https://github.com/sparkfun/SparkFun_AS … ttings.ino
Then use those calibrated values in your data acquisition
hi TS-Russell, thank you for your response.
through this procedure i have a set of calibrated value (getCalibrated…() function), according to my light source and parameters, so i essentially have the spectrum of my light source under certain conditions of measurement.
but later, when I make an acquisition by placing a leaf in front of the sensor, is it enough for me to directly take the value returned by getCalibrated? or do I have to perform operations on raw data?
thank you very much.
