    how i can make lux meter in mikroC

    hello every one

    now days , i make a project that measure lighting with a normal LDR sensor
    using 16f877 and mikroc, (LDR connected to AN0)

    and the adc in PIC reads the voltage from LDR that connected with 10K to power, that's OK.

    but i want to make a lighting measurement that measure the light in [LUX] .

    so an one can help me about what the appropriate formula that i must use to product the reading value in {lux}.

    my greetings.
