Abstract
An acceleration sensor, a capacitance detection circuit and method, an acceleration processing circuit and method, a storage medium and an electronic device are provided. The acceleration sensor includes: a base, at least one fixed electrode fastened on the base, and at least one mass movable relative to the fixed electrode. The mass includes a conductive electrode, the conductive electrode and the fixed electrode are configured to form a capacitor, and a capacitance value of the capacitor is variable due to movement of the mass relative to the base.
