The 1143 Light sensor can measure ambient light up to 70 kilolux (roughly
equivalent to the brightness of direct sunlight). Each sensor has
been individually calibrated, and a label has been applied to the
back of the board with a calibration value which can be used in your
calculations to increase measurement accuracy. The sensor's output
is logarithmic, so it will be more accurate at low light levels.
Some light sensors report drastically different values depending on
the type of light being detected. The 1143 light sensor, however,
only differs by a factor of 1.2 when measuring fluorescent light versus
If you want greater resolution with a smaller measurement range, take
