摘要 |
An apparatus for recording a vital parameter is described, which apparatus has the following features: an optoelectronic sensor arrangement (1130) for recording the vital parameter by means of light reflection at a finger, wherein the optoelectronic sensor arrangement has a first light source (1310) for producing light in the visible wavelength range, a second light source (1320) for producing light in an invisible wavelength range and a light-sensitive element (1330); and a control device (1410) which is designed to connect the second light source (1320) at intervals of time, to use the received light in the invisible wavelength range to check whether a finger is resting on the optoelectronic sensor arrangement (1130), and to connect the first light source (1310) as soon as this is the case. |
