Abstract: In an embodiment a sensor device for arrangement on a mouth-nose protection includes a sensor unit having at least one sensor element configured to detect individual breathing processes of a user when the mouth-nose protection with the sensor device is used by a user and an evaluation unit configured to count the breathing processes of the user depending on a detection signal provided by the sensor unit and provide an evaluation signal for a signaling unit depending on a determined number of breathing processes.
