1. A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:a sensing chamber;a tube communicating the interior of said cooking device and the sensing chamber in order to convey a stream of ambient air and a stream of at least a portion of smoke and/or gas generated during cooking to the sensing chamber;a detector associated with said chamber in order to measure a parameter of the smoke and/or gas in the chamber during cooking, wherein said stream of ambient air is located between said detector and said stream of at least a portion of the smoke and/or gas in the chamber; anda controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter. 2. The assembly of claim 1, wherein the controller controls a heating temperature of the cooking device in response to the measured parameter. 3. The assembly of claim 2, wherein the controller controls a cooking time of the cooking device in response to the measured parameter. 4. The assembly of claim 1, wherein the controller controls a cooking time of the cooking device in response to the measured parameter. 5. The assembly of claim 1, wherein the controller shuts off a heating assembly of the cooking device in response to the measured parameter. 6. The assembly of claim 1, wherein the controller initiates an alarm signal in response to the measured parameter. 7. The assembly of claim 1, said smoke detector being an infrared smoke detector. 8. A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:a sensing chamber;a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of smoke generated during cooking to the sensing chamber;a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking;a controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter; anda valve interposed in said passageway for selectively establishing or terminating the communication between said oven interior and said chamber. 9. A cooking device controlling assembly for use with a cooking device having an interior and at least one item being cooked, said assembly comprising:a sensing chamber;a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of smoke generated during cooking to the sensing chamber;a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking;a controller coupled with said detector and cooking device that controls at least one cooking device function in response to the measured parameter;said chamber presenting an oven gas inlet and an oven gas outlet whereby gas from said oven including said smoke passes through the sensing chamber; andsaid chamber further having an ambient gas inlet and an ambient gas outlet arranged so that a stream of ambient air passes through the sensing chamber during passage of said oven gas there through, said stream of ambient air passing between said detector and said oven gas. 10. A cooking device controlling assembly for use with a cooking device having interior and at least one item being cooked, said assembly comprising:a sensing chamber;a tube communicating the interior of said cooking device and the sensing chamber in order to convey a stream of ambient air and a stream of at least a portion of smoke and/or gas generated during cooking to the sensing chamber;a smoke detector associated with said chamber in order to measure a parameter of the smoke in the chamber during cooking, wherein said stream of ambient air is located between said detector and said stream of at lea st a portion of the smoke and/or gas in the chamber; anda controller coupled with said detector and cooking device that controls at least one oven function in response to the measured parameter. 11. The assembly of claim 10, wherein the controller controls a heating temperature of the cooking device in response to the measured parameter. 12. The assembly of claim 10, wherein the controller controls a cooking time of the cooking device in response to the measured parameter. 13. The assembly of claim 10, wherein the controller shuts off a heating assembly of the cooking device in response to the measured parameter. 14. The assembly of claim 10, wherein the controller initiates an alarm signal in response to the measured parameter. 15. The assembly of claim 10, further comprising:a gas detector associated with said chamber in order to measure a parameter of the gas in the chamber during cooking. 16. The assembly of claim 15, said gas detector being H2O vapor detector. 17. The assembly of claim 15, said gas detector being CO2 detector. 18. The assembly of claim 10, said gas detector is a multi-component gas detector measuring concentration of several gases. 19. A cooking device controlling assembly for use with a cooking device having interior and at least one item being cooked, said assembly comprising:a sensing chamber;a passageway communicating the interior of said cooking device and the sensing chamber in order to convey at least a portion of at least one gas generated during cooking to the sensing chamber;a gas detector associated with said chamber in order to measure a parameter of the gas in the chamber during cooking;a controller coupled with said detector and cooking device that controls at least one oven function in response to the measured parameter; anda valve interposed in said passageway for selectively establishing or terminating the communication between said oven interior and said chamber. 20. A method of controlling a cooking device for cooking at least one item, said method comprising the steps of:using a detector to measure through a tube, a parameter of(a) at least a portion of smoke emitted by the item during cooking or (b) at least one gas emitted by the item during cooking;directing a stream of ambient air between said detector and said portion of smoke or said gas; andcontrolling at least one oven function in response to the measured parameter. 21. The method of claim 20, wherein the controlling step includes controlling a heating temperature of the cooking device in response to the measured parameter. 22. The method of claim 20, wherein the controlling step includes controlling a cooking time of the cooking device in response to the measured parameter. 23. The method of claim 20, wherein the controlling step includes shutting off a heating assembly of the cooking device in response to the measured parameter. 24. The method of claim 20, wherein the controlling step includes initiating an alarm signal in response to the measured parameter. 25. The method of claim 20 further comprising the step of:using a valve in the tube to establish or terminate communication of smoke or gas interposed in said tube.
