NOVELTY - The electronic control system has a combustible gas detector or a toxic gas detector connected to a microcontroller. The control system also has a telecommunication network interface with low latency communication mode and high latency communication modes. The communication modes are controlled by the microcontroller with the output from the gas detector.    USE - For domestic cooking e.g. grilling with various settings e.g. for grilling shell fish, fowl, pork, lamb, beef, vegetables, breads etc at various cooking temperatures, using gaseous fuel such as propane. Also for external cooking such as barbecue.    ADVANTAGE - The system operates in pulse operation mode with short stabilization period which reduces power consumption even during continuous operation. Suits for usage even at remote locations, outdoor cooking. Requires less maintenance as optical detectors are used which are unaffected by temperature changes.    DETAILED DESCRIPTION - The electronic control system has a user input for setting the desired cooking conditions. The microcontroller controls the cooking fuel combustion rate proportionally using a proportional fuel control valve based on the user input and output from a temperature sensor which determines the temperature at least from two portions of the food being cooked and produces a cooking completion signal when desired cooking state is reached. The temperature sensor is wireless connected to the microcontroller. The microcontroller is connected to a combustible gas detector such as an optical hydrocarbon detector, a toxic gas detector or a partial combustion product detector that monitors the presence of combustible gases or partially combusted gaseous products, so that the microcontroller produces an alert signal when the presence of combustible gases exceed a threshold. The combustible gas detector which is arranged in the propane grill, has an infra-red light emitting diode (IR-LED) that is intermittently actuated with a duty cycle of less than 25% to emit photons at a wavelength for selective interaction with hydrocarbons present in the atmosphere, and is associated with a detector (7) for checking the selective interaction. An alarm monitor receives the output of the detector and compares the measured hydrocarbon level with a specified value. The microcontroller is connected to a remote user interface through a wireless telecommunication network interface such as wireless switched packet network for communicating with a packet switched communication network    DESCRIPTION OF DRAWING(S) - The figure is the block diagram of gas sensing system.
