1. A self-testing fire sensing device, comprising:
a gas source configured to release one or more gases at a gas level sufficient to trigger a fire response; and
a gas sensor, including a microcontroller having a memory and a processor, configured to:
measure a gas level of the one or more gases in the self-testing fire sensing device upon the gas source releasing the one or more gases;
determine an airflow rate based on a change in the measured gas level over time; and
determine whether the self-testing fire sensing device is functioning properly based on the airflow rate.
