PZEM-004T Current Voltage Power Energy Multimeter Module AC 80-260V 100A with Current Transformer

Product Information

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).

Please note, to do testing using the application, you need a USB to Serial TTL hardware which is quite widely available in the market such as: type CH340, type PL2303 etc. as shown below. USB to Serial TTL Please note that metering chip inside of PZEM module is powered from AC side and it has to be on during startup of ESPHome device, othervise measure results won’t be visible. It should be noted that the protocols used in PZEM-004T V2.0 and PZEM-004T V3.0 are different, so the library and programming are also different. Many people think that the PZEM-004T module is corrupt or doesn’t work just because they don’t know and are using the wrong library. Bharat Pi is an IoT prototyping board for students, innovators, startups, and developers. A simplified board with an all-in-one compute, network and storage on a single board to build rapid prototypes. I am trying to connect a PZEM004T (without display) to a USB port on my PC via a USB-TTL adapter board.Data Centers: Data centers require precise monitoring of power usage and cooling systems. PZEM sensors can be used to monitor power consumption and temperature to ensure efficient operations and prevent equipment failures due to overheating. as far as i can remember (sorry but my pzem04 is left alone with a remote bluetooth serial dongle inside the electrical panel and i have no access to it..) i could not get it to work with the serial port of the raspberry, i had to use a dedicated USB to serial adapter, so yes: it should work.

VORWEG, WEISE ICH DARAUF HIN, DASS ICH KEINERLEI HAFTUNG ÜBERNEHME UND ICH SAGEN WILL, DASS DER ANSCHLUSS DER PZEM-004T MODULE VON EINEM AUSGEBILDETEN ELEKTRIKER ÜBERNOMMEN WERDEN SOLLTE UND NICHT VON EINEM LEIHE! At the beginning of the program, the Preferences library is initialized with a unique namespace, which will be used to store the configuration settings. Whether you are a maker, student, researcher, developer, product creator, or entrepreneur, there's a lot to learn and develop in robotics, internet of things (IoT), automation, artificial intelligence (AI), and STEAM education. Den Wemos und 1 Pzem-004t Modul wie im obigen Schaltplan verschalten (Es darf nur 1 Modul angeschlossen sein!!!) The only thing i hate of this little and cheap thing is that you can't have a simultaneous reading of data.Enables communication to Peacefair PZEM-004T v3.0 Power and Energy monitor using the Serial interface PZEM-004T is an electronic module that functions to measure: Voltage, Current, Power, Frequency, Energy and Power Factors. With the completeness of these functions / features, the PZEM-004T module is ideal for use as a project or experiment for measuring power on an electrical network such as a house or building.

The serial communication function (comes with TTL serial interface, through various terminals to communicate with the adapter plate, read, and set the parameters).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. It is recommended to use GPIO1/GPIO3 or GPIO13/GPIO15 for the most reliable serial communications. When using other GPIOs software serial will be activated and used. GPIO Your ESP shall be powered by an external power supply and cannot be connected to the PZEM for power.

Route one of the power output wires through the PZEM-004T core and connect the output wires to the Sonoff Basic output.
