reading books for intensity of illumination:50--60;
home video standard intensity of illumination:1400.

Board Schematic
J1 is interfacing connector
U1 is voltage regulator which gives out 3V to board from 3.3-5V supply input
Q1 is bidirectional data level translator for 5V to 3V level conversion
D1 is unidirectional clock level translator for 5V to 3V level conversion
Please note that the "addr" Pin is to assign a different I2C address to the sensor.
