A capacitance detection apparatus and an electronic device are disclosed. The capacitance detection apparatus includes: a sensing module, a connecting circuit, and a differential detection circuit for detecting changes in capacitance of the sensing module; the sensing module comprises: a substrate, and a first sensing layer and a second sensing layer respectively located on two sides of the substrate; a first sensing unit of the first sensing layer is opposite to a second sensing unit of the second sensing layer, and the first sensing unit covers the second sensing unit; the first sensing unit and the second sensing unit are electrically connected to the differential detection circuit. When a detection object approaches the capacitance detection apparatus, the capacitance of the first sensing unit is influenced by the temperature and the detection object, and the capacitance of the second sensing unit is only influenced by the temperature.
