In this paper, we propose a temperature sensor based on the θ-shaped microfiber resonator. The numerical researched results indicate that the temperature sensing sensitivity of the resonator is closely related to the microfiber diameter and the external refractive index (ERI), while it has little dependence on other parameters. As the microfiber diameter is 1 μm, it reaches the peak value of 2.09 pm/℃. Additionally, as the ERI increases, it improves gradually, then decreases sharply. When the ERI locates at 1.25 to 1.28, it keeps a constant value of about 2.8 pm/℃..
