This Peacefair PZEM-004T Multi-function AC Power Monitor is very popular in electrical consumption measurement projects. It is capable of measuring four interrelated electrical variables as voltage, current, power, and energy. RoboticsBD
This tiny PZEM-004T circuit is great for measuring AC (RMS) voltage, current, and power (single-phase). The unit easily interfaces with Arduino and other hardware using the code library. RoboticsBD
Simply power the board with a power supply (or you can use the AC source you are measuring) and connect the circular sensor to the board. Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. The circuit also comes with a TTL to USB adapter wire for easy connection to a computer or microcontroller. RoboticsBD
This module features a TTL serial data communication interface, you can read and set the relevant parameters via the serial port; but if you want to communicate with a device which has USB or RS232 (such as a computer), you need to be equipped with different TTL pinboard (USB communication needs to be equipped with TTL to USB pinboard; RS232 communication needs to be equipped with TTL to RS232 pinboard).

The Peacefair PZEM-004T features a built-in button on the panel, used to make the electricity clear function.
Precautions:
- This module is suitable for indoor, not outdoor use.
- The applied load should not exceed the rated power.
- The wiring should not be wrong.
Overview:
- We provide the software to connect it with the PC. If you want to connect it with other terminal device such as PLC,SCM and so on, please prepare the fitable cable and write the program by yourself.
- This document describes the specification of the PZEM-004T AC communication module, the module is mainly used for measuring AC voltage, current, active power, frequency, power factor and active energy, the module is without display function, the data is read through the TTL interface.
Features :
- Electrical parameter measurement function (voltage, current, active power, power).
- The power button clear function.
- Power-down data storage function (cumulative power down before saving).
- PC PC display function (display voltage, current, active power, power).
- The serial communication function (comes with TTL serial interface, through various terminals to communicate with the adapter plate, read, and set the parameters).
