It is determined whether the first ambient temperature is below a specified temperature or whether the first flame range is within a specified range. If the first ambient temperature is below a specified temperature or the first flame range is within a specified range, then returning to the first ambient temperature or the first flame range of the sensing heating module. If the first ambient temperature exceeds the specified temperature or the first flame range exceeds the specified range, the heating module is turned off, and the second ambient temperature or the second flame range of the heating module is sensed. It is determined whether the second ambient temperature is less than the first ambient temperature or whether the second flame range disappears. If the second ambient temperature is not less than the first ambient temperature or the second flame range does not disappear, a strain step is performed.

Another embodiment of the present invention provides a kitchen state alerting method comprising the following steps. Sensing the first ambient temperature or first flame range of the heating module. It is determined whether the first ambient temperature is below a specified temperature or whether the first flame range is within a specified range. If the first ambient temperature is below a specified temperature or the first flame range is within a specified range, then returning to the first ambient temperature or the first flame range of the sensing heating module. If the first ambient temperature exceeds the specified temperature or the first flame range exceeds the specified range, the activity of the person in the vicinity of the heating module is sensed. Determine if there is any activity near the heating module. If there is personnel activity in the vicinity of the heating module, return to the first ambient temperature or the first flame range of the sensing heating module. If there is no human activity in the vicinity of the heating module, the second ambient temperature or the second flame range of the heating module is sensed after the heating module is turned off. It is determined whether the second ambient temperature is less than the first ambient temperature or whether the second flame range disappears. If the second ambient temperature is not less than the first ambient temperature or the second flame range does not disappear, a strain step is performed.

Another embodiment of the present invention provides a kitchen state warning system including a heating module, a switch, a sensing module, a control module, and a strain module.
