Ambient light

The following algorithms are based on 5 channel ambient light signals that can be acquried by the movisens sensors LightMove 3 or LightMove 4.

Illuminance (Illuminance)

This parameter calculates the level of ambient light in an adjustable output interval. The unit is [lux].

Color temperature (ColorTemperature)

This parameter calculates the color temperature in an adjustable output interval. The algorithm outputs the value -1 if the color temperature is not calculable (darkness). The unit is [K].

Light Situation detection (LightSituation)

It’s possible to estimate the current light situation based on a multichannel ambient light sensor. This parameter describes the type of light captured by the sensor in an adjustable output interval. The following table displays the relevant coding:

Light Situation	Coding
Darkness	0
Incandescent Light	1
Daylight/Sunlight	2
Daylight/Cloudy	3
Fluorescent	4
LED	5
Daylight Lamp	6
Mixed Light	7
Unknown	99
