When an external control unit is needed to perform data reading, control, power supply and other operations on the temperature sensors 10 in the temperature sensor group, only the first conductive unit 13 or the second conductive unit 14 of the temperature sensor 10 located at the end portion needs to be connected with the control unit, and thus the external control unit can simultaneously and uniformly control a plurality of temperature sensors 10. Meanwhile, when the number of the temperature sensors 10 needs to be increased, the temperature sensors 10 which need to be increased are only connected with the temperature sensor 10 at one end; in the same way, when the number of the temperature sensors 10 needs to be reduced, the temperature sensors 10 only need to be taken down from the end part, so that the number of the temperature sensors 10 can be increased and reduced at will according to the needs, and the setting is convenient and flexible.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
