A temperature controller is disclosed in the invention, and the temperature controller includes one dry battery, a voltage conversion circuit connected with outputs of the battery and a temperature controller control circuit connected with the voltage conversion circuit. The voltage conversion circuit provides a power supply for the temperature controller control circuit. The temperature controller in the invention requires only one battery as the power supply, so that energies are saved, and the temperature controller is reduced in size and can be mounted more easily.
