Tune parameters for equation to get lux from register value.
How to tune parameters.
Place system into dark chamber.
Place halogen/led lamp. We can change lux from lamp.
Read data0 and data1 from two different devices.
Then we will get two equation from test.
Solve equation to get/calculate constant value as light source.

Parameter can be changed as chassis.
