## Abstract

An automatic smoke/carbon monoxide detection system and method are described that are configured to automatically shut off power supplied to an appliance/equipment, a room of a structure, a zone within a structure, or an entire structure upon detection of smoke/carbon monoxide/hazardous gases. A system and method are further described herein that are configured to connect to an on-board diagnostic port, where upon detection of smoke/carbon monoxide/hazardous gases exceeding a certain level, an alert is displayed/sounded so that the driver/passenger of the vehicle can act appropriately. Alternatively, a command may be issued to shut off the engine of the vehicle to immediately halt the production of deadly gases.
