Application skills/Implementation of AC sampling technology in power monitoring system based on single chip microcomputer [Copy link]

The system uses 8031 single-chip microcomputer to realize AC sampling of power parameters, displays the real-time values of frequency, voltage and current through LED display, gives sound and light alarm when overvoltage reaches 30% and undervoltage reaches 30%, and can print voltage, current and frequency values regularly. Practice has proved that the power parameters such as voltage, current, active power and power factor obtained by algorithm calculation using AC sampling method for data collection have good accuracy and stability.
