The utility model discloses a wide range electric energy meter based on a hall sensor. The electric energy meter comprises a hall current detection module, a voltage detection module, an MCU signal processing and controlling module, a metering module, a displaying and alarming communication module, and a power supply module. The hall current detection module can detect the current change and then sends the measurement results to the metering module and the MCU signal processing and controlling module. The voltage detection module measures the voltage and sends the measurement results to the metering module. The metering module sends the processing results to the MCU signal processing and controlling module. The MCU signal processing and controlling module processes and stores the signals outputted by the metering module, and switches the current detection measurement range according to the current strength from the hall current detection module. The displaying and alarming communication module comprises an LCD display module, an alarming module, and a communication module. The power supply module supplies power for all the modules mentioned above. The provided electric energy meter can measure direct current and high frequency nonlinear component and has a high performance on resisting external magnetic field interference.
