	The 1142 is Non-Ratiometric which means that you cannot rely on the sensor saturating at 1000 SensorValue. To be conservative, interpret SensorValue over 950 as saturated, with the true light level being unknown.

			===Sensitivity Response===

			The 1142 uses the APDS-9002 light sensor package. The following graph illustrates the sensor's sensitivity to specific wavelengths of light.

If for some reason you can't use the calibration values that come with the sensor, you can use the generalized values of ''' m = 1.478777''' and '''b = 33.67076''' to get a rough approximation.

==Technical Details==
The human eye is less sensitive to changes in light intensity than the 1142, but is able to see a wider range. The Human eye range is from 50 µlux (starlight) to 100 klx (extremely bright sunny day). The 1142, on the other hand, is able to measure from 1 lux (Moonlight) to 1000 lux (TV studio lighting). If you notice noise on the signal that you cannot perceive yourself, it could be due to incandescent light flicker, or other varying light sources.

The 1142 is Non-Ratiometric which means that you cannot rely on the sensor saturating at 1000 SensorValue. To be conservative, interpret SensorValue over 950 as saturated, with the true light level being unknown.

===Formulas===
The formula to translate SensorValue into luminosity is:

:<math>
\text{Luminosity (lux)} = \text{SensorValue} \!
</math>
