Abstract

In an embodiment a sensor device includes a first optoelectronic emitter configured to irradiate a spot with electromagnetic rays, a second optoelectronic emitter configured to irradiate the spot with electromagnetic rays, a detector configured to detect electromagnetic rays from the first and second emitters reflected at or transmitted through the spot, wherein the electromagnetic rays of the first emitter have a wavelength in a range of 1400-1500 nm, wherein the electromagnetic rays of the second emitter have a wavelength in a range of 900-1100 nm, and wherein the second emitter is configured to emit at least one further electromagnetic signal, the one further electromagnetic signal not being used for measuring a humidity.
