Abstract: An automatic smoke/carbon monoxide evacuation system for a building having at least one existing ventilation fan and at least one ventilation passageway to outside the building is provided. The system includes a microprocessor and a smoke/carbon monoxide sensor coupled to the microprocessor and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. A power switch is coupled to the existing ventilation fan and is configured to automatically connect the existing ventilation fan to a power source in response to the trigger signal, so that the ventilation fan rotates at a high speed to ventilate the detected smoke/carbon monoxide via the existing ventilation passageway. An alarm device is further communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

Abstract: An automatic smoke/carbon monoxide evacuation system for a garage equipped with a garage door and garage door opener with a motor is provided. The system includes a microprocessor, and a smoke/carbon monoxide sensor incorporated in a garage door reverse sensor of the garage door opener and coupled to the microprocessor, and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. The system further includes a power switch coupled to the motor and configured to automatically connect the motor to a power source in response to the trigger signal to automatically open the garage door to ventilate the detected smoke/carbon monoxide in response to the trigger signal. An alarm device is communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

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.
