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

Product Information

Just one thing comes to my mind, the pzem004t v1 and v2 (not sold anymore) need the pzem004t component in esphome. Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. Install Tasmota on the Sonoff Basic and confirm it is functional before connecting the PZEM-004T to its serial interface.

This tiny PZEM-004T circuit is great for measuring AC (RMS) voltage, current, and power (single-phase). I wanted to add energy monitoring to my home automation setup, without too much custom hardware, but it had to be relatively cheap.just a 5v source for the pzem004t and the esp (the esp m3 uses a ams1117 to get the voltage down to 3. In addition there is also the PZEM-004T 100 Ampere which uses the Current Transformer split core model. The PZEM-004T together with a HW-655 Relay provide a good clamp-on energy monitor for a 240V clothes dryer.

However, on the images I see that the mains isolation is made by 2 optocouplers, (one for Rx the other for Tx). I take it your feed is 500 A per phase, and you haven’t calculated that from a VA rating, which would be the total across all three phases?Correct , I would then use the solid core PZCT-02 ct rather than the split core ct as it would be it would be unnecessary to have a split core for the first ct. I am trying to connect a PZEM004T (without display) to a USB port on my PC via a USB-TTL adapter board. Cayenne is a product from myDevices that allows you to not only display data but also set up triggers, monitor devices, control devices, etc. It can be used a SMD resistor 102 or 1001 (1K) soldered near/parallel with R8 or a normal resistor (THT) similar to that used on the image of v. I read 24 mV (resolution 1 mV) at 50 A indicated (50 mA secondary current), which makes the instrument appear as a burden resistance of 0.

This module is equipped with 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 computer), you need to be equipped with different TTL pin board (USB communication needs to be equipped with TTL to USB pin board; RS232 communication needs to be equipped with TTL to RS232 pin board), the specific connection type as shown in Figure 2. I have three PZEM v4, powered at 3v3 from a single Wemos D1 mini, using the diode multiplexing suggestion in this thread.Einzigster Unterschied ist, wenn ich Rx und Tx beim Wemo ändere, dann geht die andere Diode im Modul an. If using the example program with Serial Hardware, Arduino Mega2560 is needed because the Arduino UNO Hardware Serial is already used for communication with Serial Monitor. Your ESP shall be powered by an external power supply and cannot be connected to the PZEM for power. 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.

As most parts are connected to high voltage AC it is recommended to fit the hardware in a solid enclosure. This Peacefair PZEM-004T Multi-function AC Power Monitor is very popular in electrical consumption measurement projects. Mit der Software kann übrigens das Gerät auf Funktion überprüft und auch Kalibriert werden, wenn nötig! The circuit also comes with a TTL to USB adapter wire for easy connection to a computer or microcontroller.It could be a 100-turns coil - or as many turns as will fit and give a nice round number to multiply the reading by - say 50 turns ideally. You may want to use a level shifter for the serial communications signals to bring them to the recommended 3. 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. Each parameter has “Log” checkbox which enables data logging into the text field at the bottom of the application window.
