Abstract
Disclosed are a sensing device and an image capturing apparatus. The sensing device includes a housing assembly, a pyroelectric sensor disposed on the housing assembly, a Fresnel lens and a moving assembly. The Fresnel lens includes at least two Fresnel fringe areas with different light-condensing abilities; one of the pyroelectric sensor and the Fresnel lens is fixedly connected with the housing assembly, and another of the pyroelectric sensor and the Fresnel lens is movably coupled to the housing assembly through the moving assembly. The pyroelectric sensor and the Fresnel lens move relative to each other to switch between the Fresnel fringe area corresponding to the pyroelectric sensor. The disclosure can adjust the detection range and improve the multi-scene adaptability of the sensing device.
