Abstract
A heating apparatus is provided with the gas sensor for detecting gas or steam generated from an object to be heated and a weight sensor for detecting the weight of the object to be heated. The signal level of the gas sensor indicates whether the change in the amount of the gas or the steam in the exhaust guide portion is a predetermined value of gas or steam generated from the object, to determine the kind and condition of the object to be heated. Also, change in the signal level of the gas sensor is compared to the predetermined value at a detection time period which is based on the weight of the food detected by the weight sensor, to decide whether to continue or stop heating.
