Abstract

An optoelectronic sensor component for measuring light may include a first signal channel, a second signal channel, a first light-sensitive detection assembly, a second light-sensitive detection assembly, a further light-sensitive detection assembly, and an assigned further signal channel. The first signal channel may provide a first electrical signal, which represents the intensity of light incident on the sensor component. The second signal channel may provide a second electrical signal representing the intensity of the light incident on the sensor component. The first and second light-sensitive detection assemblies may generate the first and second electrical signals, respectively, and be assigned to the first and second signal channels, respectively. Both detection assemblies may have an identical spectral sensitivity and are thus redundant with respect to one another. The spectral sensitivity of both detection assemblies may have a photopic profile. The further light-sensitive detection assembly may be configured for detecting only infrared light.
