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.

Optoelectronic sensor component for measuring light with built-in redundancy

An optoelectronic sensing device may include an optoelectronic detection device configured to detect light and provide an electrical signal as a function of detected light. The device may further include a signal detection device configured to store at least one signal value of the electrical signal in a memory during a time interval of repeating time intervals and to output an indication signal after the time interval has elapsed.

Optoelectronic sensor device, detector and electronic device, and method of operating such a sensor device or detector

A method and an optical sensor are described herein. The optical sensor may include a communication interface for receiving data from a control unit and for transmitting data to the control unit, a storage unit with at least one register for storing data, and a CRC generator for generating a CRC checksum. The optical sensor may be configured in such a way that when data stored in the storage unit is to be transmitted to the control unit, the communication interface receives from the control unit a device address specific to the optical sensor and an address of a register in which the data to be transmitted is stored. The CRC generator may be initialized using the device address received from the communication interface and/or the register address received from the communication interface, before the CRC generator generates a CRC checksum for the data to be transmitted.
