how i can make lux meter in mikroC

[asrock]

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.

hello,

Just have a look on Texas TSL_235 sensor
convert Light to Frequency
need only a timer input....
