    photodiode or LDR.. these directly work on light interaction. you will have to use ADC for conversion. a small and powerful controller would be ATTiny13

    If you want to measure light, it must be calibrated with a known accurate light meter.

    You can measure light without calibration, but of course you're right that the result won't be in lux units without calibration.
