An AC sensor for measuring voltage and detecting power outages is disclosed. In a disclosed embodiment, the AC sensor includes a plurality of integrators for independently integrating an AC voltage present on the AC power line. It also includes a timing circuit in communication with the integrators. The timing circuit initiates the integration cycles of the integrator such that the integration cycles are staggered in time and such that every two sequentially occurring integration cycles partially overlap.
