The BL0942 is a highly integrated, calibration-free single-phase energy metering IC designed for smart plugs, smart sockets, power strips, and energy-aware appliances. It provides accurate measurement of active power, voltage RMS, current RMS, line frequency, and zero-crossing information, while supporting both pulse output and register-based digital interfaces. Often compared with the popular BL0937, the BL0942 is not merely a pin-compatible refresh, but a more capable, register-driven metering IC intended
