A method and apparatus for operating a multi-gas sensor are disclosed. In an embodiment, a method includes providing at least one calibration input comprising sensor design data of the multi-gas sensor, which varies dependent on production process parameters, and/or sensor production process parameter data of the multi-gas sensor, and/or measurement results of the multi-gas sensor captured when the multi-gas sensor is exposed to one of the gases or a gas mixture to be detected and/or sensed by the multi-gas sensor; providing a trained neural network including an input layer with K input nodes, an output layer with L output nodes and at least one hidden layer; storing each calibration input as a fixed input to a corresponding input node of the trained neural network; and providing a multi-gas sensor output for at least a part of the gases to be detected and/or sensed by the multi-gas sensor dependent on the trained neural network and actual measured sensor values from the sensor elements.

Method and apparatus for operating a multi-gas sensor

A sensor component and a mobile communication device including a sensor component are disclosed. In an embodiment a sensor component includes a subcomponent configured to sense a gas level including a resistive heater and a gas sensitive element disposed on the resistive heater; a package enclosing a cavity and accommodating the subcomponent, the package including a first opening in a position facing the gas sensitive element of the subcomponent and a second opening configured to allow a flow of gas to enter the package through the first opening and exit the package through the second opening; and an evaluation circuit configured to generate an output signal indicative of a speed of the flow of gas in response to electrical power to be supplied to the resistive heater.
