FAQ
HI !
I use the code and library in https://www.dfrobot.com/wik...
,then test VEML7700 and Illuminance instrument in my room,value is same
but whan I take them test in the sunshine, Illuminance instrument get value is 40000lx ,but VEML7700 value just 2000lx
is anything wrong in code, library or just can't test VEML7700 in the sunshine?
According to Spectral energy distribution of the sun, I do not think so different period of the day get value Will be correct.
Interestingly,I test Flashlight on the phone very close and get value also wrong ,I think it just can't test value too large with code
