PZEM-004T AC Power & Energy Monitoring Module
The PZEM-004T is an AC electrical measurement module designed to monitor the electrical characteristics of an AC load. Depending on the version, it can measure parameters such as AC voltage, current, active power, accumulated energy, frequency and power factor.
The module communicates with a host controller through a serial interface, making it suitable for integration with Arduino, ESP32, Raspberry Pi and other embedded systems. A current transformer is used for non-invasive current measurement on supported versions, allowing the controller to monitor electrical loads without routing the full load current through the measurement electronics.
The PZEM-004T is useful for electricity monitoring, smart-home projects, IoT energy meters, solar and backup-power monitoring, appliance monitoring and electrical load management.
