Hi all,

I want to measure the brightness using a light dependent resistor ''LDR'' uisng the stm32l15x devices. I an thinking to use the ADC to measure the ldr output but the the curve of the resistance vs illumination flux shows a logarithmic function.

Is there somebody who did it?

Thnaks & Regards,

Thanks Erik, this link helps me too. I should find a economic solution for Lux measurement for lighting control at work environments.

not only economical, but quite precise and easy to implement
