PZEM-004T AC Energy Monitoring Module

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).

Other instructions:

The TTL interface of this module is a passive interface, it requires external 5V power supply, which means, when communicating, all four ports must be connected (5V, RX, TX, GND), otherwise it cannot communicate.

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
