1. An optoelectronic sensor component configured to measure light, comprising:
a first signal channel configured to provide a first electrical signal, which represents an intensity of light incident on the optoelectronic sensor component;
a second signal channel separate from the first signal channel in terms of signaling, wherein the second signal channel is configured to provide a second electrical signal independent of the first electrical signal, and wherein the second signal channel represents an intensity of the light incident on the optoelectronic sensor component;
a first light-sensitive detection assembly configured to generate the first electrical signal, and wherein the first light-sensitive detection assembly is assigned to the first signal channel;
a second light-sensitive detection assembly configured to generate the second electrical signal, and wherein the second light-sensitive detection assembly is assigned to the second signal channel;
wherein the first light-sensitive detection assembly and the second light-sensitive detection assembly have an identical spectral sensitivity and are thus redundant with respect to one another, and wherein the identical spectral sensitivity of the first light-sensitive detection assembly and the second light-sensitive detection assembly has a photopic profile;
an assigned third signal channel; and
a third light-sensitive detection assembly configured to detect only infrared light.
