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

Product Information

Examples of PZEM-004T modules that use CT split core can be seen in the image below PZEM-004T CT Split Core Specifications / Features PZEM-004T As most parts are connected to high voltage AC it is recommended to fit the hardware in a solid enclosure. Software configuration ~

Purpose: The Preferences library is commonly used in Arduino and ESP8266/ESP32 projects to store and retrieve configuration settings on the microcontroller's non-volatile memory (NVRAM). NVRAM is a memory that retains data even after the power is disconnected, making it ideal for storing user preferences or configuration parameters. I used the logger settings: VERY_VERBOSE. But I can’t understand whether pzem004t works or not. [16:17:54][I][app:100]: ESPHome version 1.14.3 compiled on Nov 26 2019, 16:12:47 After testing or testing the function and confirmed that the PZEM-004T V3.0 module is functioning properly, it can be continued by making a program with Arduino or other microntroller. Code ProgramYou can use a voltage level shifter to power the ESP82xx from the PZEM-016 module's 5V power. This may also require a 470uf 35V capacitor across the 5V line to work reliably. Tasmota Configuration ~ I am trying to connect a PZEM004T (without display) to a USB port on my PC via a USB-TTL adapter board. Den Wemos und 1 Pzem-004t Modul wie im obigen Schaltplan verschalten (Es darf nur 1 Modul angeschlossen sein!!!) Although there are some differences between PZEM-004T V2.0 and PZEM-004T V3.0, functionally or featureally, both have similarities. Following are the features or specifications of the PZEM-004T module : include /* Hardware Serial2 is only available on certain boards. * For example the Arduino MEGA 2560 */

In the example program to access or interfacing the PZEM-004T V3.0 module using this Arduino, we use the following library : VV][scheduler:131]: Running interval 'update' with interval=60000 last_execution=93078 (now=153079) Note: 14 in the sending command is the alarm value (14 is a hexadecimal data representation, which converted to decimal is 20). What you should note is the power alarm value of this module is based on KW units, which means the minimum alarm value is 1KW, the maximum value is 22KW. I was a bit surprised at the 10V drop when I turned on the kettle! Also, you might notice that VxA is not exactly W. I don't know if this is because I do the readings a second apart, or because of power factor, or because of something else. I'll look into it.) VV][scheduler:185]: Running interval 'update' with interval=60000 last_execution=110569 (now=170576)In addition there is also the PZEM-004T 100 Ampere which uses the Current Transformer split core model. Because it uses a split core, of course it has advantages in its ease of use because it can be directly installed on a power network cable that is already installed without having to remove the power cable. The Version 3.0 PZEM is an upgraded version of the older PZEM-004T for which you can find the library Here Main features IoT-Based Energy Management: Integrating PZEM sensors with IoT platforms enables remote monitoring and control of power consumption. IoT applications can analyse data, generate insights, and trigger actions based on energy consumption patterns.

For connection or connection between PZEM-004T V3.0 with Current Transformer (CT), Load and Arduino in full can be seen in the picture below : Wiring PZEM-004T with Load PZEM-004T V3.0 Module Function Testing Note: the PZEM-016 TTL output is at 5V signal levels. There are varying schools of thought on whether the ESP82xx has 5V tolerant GPIO. You may want to use a level shifter for the serial communications signals to bring them to the recommended 3.3V. Note: Reply power data is D1D2 = 08 98, converts 08 98 to decimal is 2200, so the current voltage value is 2200W. Install Tasmota on the Sonoff Basic and confirm it is functional before connecting the PZEM-004T to its serial interface. Hardware connections ~Da aber die Module, von Werk aus, die Adresse Nummer 1 haben, müssen nur bei 2 Modulen die Adressierung vorgenommen werden und dass geht mit dem Herstellertool oder über Tasmota, ich erkläre beide Möglichkeiten: Somit ist die Adressierung abgeschlossen und Ihr könnt die Module wie im oben abgebildeten Schaltplan anschließen und alles unter Spannung nehmen (Immer zuerst die PZEM Module). putX: These methods store values of various data types (e.g., putInt, putFloat, putString) in the preferences identified by a key (name). For example, putInt("someKey", 42) stores the integer value 42 with the key "someKey". Sending commands and replying data automatically are as shown above, the data are expressed in hexadecimal; the last byte of the sending and replying data are 1E and A4, belong to cumulative sum. At sending commands: B4 + C0 + A8 + 01 + 01 + 00 = 21E (use the hexadecimal addition), the cumulative sum data is 21E, take the last two bytes 1E to be used the cumulative sum data in sending commands; data in reply: A4 + 00 + 00 + 00 + 00 + 00 = A4 (use the hexadecimal addition),the cumulative sum data is A4,which is the cumulative sum data in reply. Per Theo - As the PZEM is a dedicated energy monitor, device calibration in TASMOTA is currently not supported. PZEM-016 ~
