A camera module includes a lens assembly, a module bracket, a first limit member, a first deformable member, and a second deformable member. The lens assembly is rotatably connected to the module bracket. The first limit member is fastened to the lens assembly or the module bracket. The first and second deformable members are both electro-deformable members. The first and second deformable members are respectively disposed on two opposite sides of the first limit member. When the lens assembly rotates with respect to the module bracket along a first direction, the first deformable member deforms, so that a first rotation angle of the lens assembly is measured. When the lens assembly rotates with respect to the module bracket along a second direction, the second deformable member deforms, so that a second rotation angle of the lens assembly is measured, the second direction being opposite to the first direction.
