Method and device for evaluating signals of a sensor unit including at least two sensors

A device configured to evaluate signals of a sensor unit including at least two sensors, the device configured to:

• read in:
• (i) at least one first sensor value of a first sensor of the sensors of the sensor unit and at least one second sensor value of a second sensor of the sensors of the sensor unit, each of the first and second sensor values representing one parameter of substance to be measured by the sensors or a linking of the parameters, and (ii) a threshold value range which maps a range of combinations of at least the first and second sensor value, which represents a presence of or a value of the substance to be measured in surroundings of the first and second sensors;
• recognize that a combination of the read-in first and second sensor values is outside the threshold value range;
• and
• change the threshold value range into a changed threshold value range in such a way that the combination of the read-in first and second sensor values is within the changed threshold value range, the changing of the threshold value range being carried out when the combination of the read-in first and second sensor values meets a change criterion.

A non-transitory machine-readable memory medium on which is stored a computer program for evaluating signals of a sensor unit including at least two sensors, the computer program, when executed by a computer, causing the computer to perform the following steps:

• reading in:
• (i) at least one first sensor value of a first sensor of the sensors of the sensor unit and at least one second sensor value of a second sensor of the sensors of the sensor unit, each of the first and second sensor values representing one parameter of substance to be measured by the sensors or a linking of the parameters, and (ii) a threshold value range which maps a range of combinations of at least the first and second sensor value, which represents a presence of or a value of the substance to be measured in surroundings of the first and second sensors;
• recognizing that a combination of the read-in first and second sensor values is outside the threshold value range;
• and
• changing the threshold value range into a changed threshold value range in such a way that the combination of the read-in first and second sensor values is within the changed threshold value range, the changing of the threshold value range being carried out when the combination of the read-in first and second sensor values meets a change criterion.
