What is the version of the board?

Please contact us for more information.

Is this version 1.0 or version 3.0 ? Photo says 3.0

Please contact us for more information.

my pzem004t shows wrong power factor around 0.05 in pure resistive load, any one have any idea how to correct or what is the problem.

Please contact us for more information.

Is there a version of this product which can be used for 3 phase power measurement instead of buying three separate ones?

Sorry, version of this product for three phase power measurement is not available in our store

Can this be interfaced with Esp-32-s3?

Yes, the ESP32-S3 can interface with the PZEM-004T via UART (TX to RX and RX to TX connections).

Can we get a split core sensor instead of closed core sensor

Please contact us for more information.

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. 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. 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. 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). Note : Actual product may vary in terms of version printed on it but working remains same. 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.

Note: Package does not include a USB cable

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).

Package Includes:

1 x PZEM-004T Multi-function AC Power Monitor Module

1 x CT coil

Setup Guide

Charge the battery pack

Insert the battery into the charger and plug in. Charge fully before first use — most packs take 1–3 hours. The LED will turn green when complete.

Insert the correct bit or blade

Open the chuck by turning it counterclockwise. Insert the drill bit or screwdriver tip and tighten the chuck firmly by hand.

Set direction and speed

Use the forward/reverse switch to set rotation direction. Select the speed mode (low for screwing, high for drilling) if your model has multiple speeds.

Adjust the clutch

Set the clutch to a low number for driving screws (prevents over-tightening) or to the drill symbol for drilling holes.

Use safely

Always wear safety glasses. Keep the drill perpendicular to the surface. Apply steady pressure — let the tool do the work.
