Single-channel temperature measuring device applied to gas stove

The invention discloses a single-channel temperature measuring device applied to a gas stove, which is characterized in that the single-channel temperature measuring device is arranged below the gas stove, and when infrared light of an object to be subjected to temperature measurement passes through the single-channel temperature measuring device to form a first light path and a second light path in sequence, the first light path and the second light path are communicated; using the single-channel temperature measuring device to detect a first radiation quantity and a second radiation quantity; the first radiation quantity is the radiation quantity of the infrared light in the first light path; the second radiation quantity is the radiation quantity of the infrared light in the second light path; and inputting the ratio of the first radiation quantity to the second radiation quantity into a preset measurement model to obtain the temperature of the object to be subjected to temperature measurement.
