Note: please check! This might only be one of the two different spectral channels and thus yield vastly incorrect LUX values when massive IR light has impact on the sensor. The lux value of N900 is a derived value from an [http://www.ams.com/eng/content/download/251504/992805/version/3 algorithm] calculating ''visible'' lux from roughly a difference between the two sensor values the ALS provides | Note: please check!

The TSL2562 and TSL2563 are second-generation ambient light sensor devices. Each contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes. Integration of both channels occurs simultaneously. Upon completion of the conversion cycle, the conversion result is transferred to the Channel 0 and Channel 1 data registers, respectively. | The TSL2562 and TSL2563 are second-generation ambient light sensor devices.
