Peacefair PZEM-004T AC Multi-function Electric Energy Metering Power Monitor

The Peacefair PZEM-004T Multi-function AC Power Monitor has gained widespread popularity in electrical consumption measurement projects. This compact device excels at measuring four essential electrical variables: voltage, current, power, and energy.

Designed for measuring AC (RMS) voltage, current, and power in single-phase systems, the PZEM-004T seamlessly integrates with Arduino and other hardware through its dedicated code library.

Operating the board is straightforward—simply power it with a suitable power supply (or the AC source under measurement) and connect the circular sensor to the board. Pass the wire through the circular sensor, and you’re ready to initiate measurements for voltage, current, and power. The module even includes a TTL to USB adapter wire, facilitating easy connections to computers or microcontrollers.

Featuring a TTL serial data communication interface, this module enables reading and setting relevant parameters through the serial port. If you wish to communicate with a device equipped with USB or RS232 (such as a computer), you’ll need different TTL pinboards (USB communication requires a TTL to USB pinboard, while RS232 communication requires a TTL to RS232 pinboard).

Notably, the Peacefair PZEM-004T incorporates a built-in button on the panel, serving the purpose of initiating the electricity clear function. This multifunctional AC Power Monitor stands out as a reliable and user-friendly tool for diverse electrical measurement applications.
