lightThe LightSensorType attribute specifies the electronic type of the light sensor. This attribute shall be set to one of the non-reserved values listed in LightSensorTypeEnum or null in case the sensor type is unknown.
Readonly
maxThe MaxMeasuredValue attribute indicates the maximum value of MeasuredValue that can be measured. A value of null indicates that this attribute is not defined. See Measured Value for more details.
Readonly
measuredThe MeasuredValue attribute represents the illuminance in Lux (symbol lx) as follows:
• MeasuredValue = 10,000 x log10(illuminance) + 1,
where 1 lx <= illuminance <= 3.576 Mlx, corresponding to a MeasuredValue in the range 1 to 0xFFFE. The MeasuredValue attribute can take the following values:
• 0 indicates a value of illuminance that is too low to be measured,
• MinMeasuredValue <= MeasuredValue <= MaxMeasuredValue under normal circumstances,
• null indicates that the illuminance measurement is invalid.
The MeasuredValue attribute is updated continuously as new measurements are made.
Readonly
minThe MinMeasuredValue attribute indicates the minimum value of MeasuredValue that can be measured. A value of null indicates that this attribute is not defined. See Measured Value for more details.
