Breathing volume measurements are therefore not easily available to sports and fitness enthusiasts. Thus, there may be a need for improved breath measurements.
According to various embodiments, a sensor device may be provided. The sensor device may include: an airflow sensor configured to generate a voltage based on an airflow; and an output circuit configured to output measurement data based on the voltage; wherein the airflow sensor is configured to provide the voltage as a power supply to the output circuit.
According to various embodiments, a method for controlling a sensor device may be provided. The method may include: controlling an airflow sensor to generate a voltage based on an airflow; controlling an output circuit to output measurement data based on the voltage; and controlling the airflow sensor to provide the voltage as a power supply to the output circuit.
