The light sensor measures the light intensity by detecting the brightness of the incident light and converting it into a digital signal. It only takes into account the light spectrum that can be perceived by the human eye and ignores infrared and ultraviolet radiation.

Light enables people to perceive their surroundings with their eyes. However, too much or too little light distorts our sensory impression. This applies to both daylight and artificial lighting. The intensity and wavelength of the light are decisive for its tolerability.
Various regulations stipulate how bright and in which wavelengths artificial light sources should shine. For example, the safety lighting of escape routes must be at least 1 lux.
For comparison: This is about as much as a candle still emits at a distance of approx. 1 meter. Typical living room lighting, on the other hand, is around 100-300 lx, while that of a modern operating theater is 160,000 lx.
The human eye perceives radiation in the wavelength range of approx. 380 - 780 nanometers (nm). It works most easily in daylight with wavelengths around 555 nm. The brightness range in which it can perceive contrasts is between 10-4 cd/m2 and104 cd/m².
These values determine the optimum illuminance for workstations: It should be at least 500 lx on average.
In Germany, recommendations for the type and direction of light and the associated protection of the eye from fatigue apply to workplaces.
In its publication "Technical Rules for Workplaces", the Federal Institute for Occupational Safety and Health (BAuA) presents the following minimum values with regard to "Lighting and line of sight" in May 2023:
Unfavorable lighting conditions can lead to concentration problems, headaches and eye pain, as well as incorrect perception and reactions. People often adopt an unfavorable posture in poorly lit environments in order to minimize visual deficits. In the long term, this can lead to incorrect strain and damage and thus to longer periods of illness.
To protect against the short- and long-lasting consequences of inadequate lighting, we recommend checking the correct light intensity.
Light is produced by the conversion of chemical energy during combustion or fusion processes or during the discharge of electrical energy. However, it can also be released through the conversion of electrical energy. Both processes take place in nature (fire, lightning, sun) as well as man-made processes (light bulb, LED).
The light sensor measures the light intensity by detecting the brightness of the incident light and converting it into a digital signal. It only takes into account the light spectrum that can be perceived by the human eye and ignores infrared and ultraviolet radiation.
