A gas stove having a temperature sensing function comprises a stove body, a temperature sensor and a gas controller. The stove body includes a burner assembly for heating a pot. The temperature sensor includes a thermopile sensor and a signal processor. The thermopile sensor senses infrared rays radiating from the pot and outputs a sensing signal. The signal processor is electrically connected with the thermopile sensor to process the sensing signal and outputs a control signal. The gas controller is electrically connected with the signal processor and adjusts a gas flow supplied to the burner assembly according to the control signal. The aforementioned gas stove senses the temperature of the pot with a non-contact manner.
