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

Product Information

PZEM-004T module is very easy to use in programming using various types of microcontroller boards such as Arduino, ESP8266, STM32, WeMos, NodeMCU, Raspberry Pi etc. For 10 wires bunched carrying 5 A, it would need derating by a factor of about 2, so the cable needs rating at 10 A - that’s 1 mm² in a thermally insulated duct according to my reference material. I'm also going to check if I can increase the length of the wire to the pickup coil without affecting the measurements. Route one of the power output wires through the PZEM-004T core and connect the output wires to the Sonoff Basic output. The modification retains the optical isolation used by the PZEM for safety to ensure no high voltages on the outputs.

PZEM-004T v3 IoT Energy Meter with Cayenne Dashboard using PZEM-004T v3

After setting-up the Cayenne Dashboard, we must test the PZEM-004T V3 meter before interfacing with the dashboard. 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.This tiny PZEM-004T circuit is great for measuring AC (RMS) voltage, current, and power (single-phase).

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. Einzigster Unterschied ist, wenn ich Rx und Tx beim Wemo ändere, dann geht die andere Diode im Modul an.PPPS: i've removed from the code the debug and logging code, so maybe i left some typo or formal mistake. and power, ok, but is this working even as a slave device (so can i connect to the sensor via bluetooth)? Many thanks to all the other contributors that add new features, find bugs and generally keep this project afloa.

PZEM004Tv30 - Arduino Reference

The Riemann calculated numbers go down sometimes, but I guess this is due to the negative W’s above. The Peacefair PZEM-004T features a built-in button on the panel, used to make the electricity clear function. SmartConnect is a smart home automation system that utilizes Altium, ESP8266, Pzem004T, Flutter app, and Firebase backend. With MQTT, resource-constrained IoT devices can send or publish information on a specific topic to a server that acts as an MQTT message broker. If you need 5V you can use directly from Sonoff (for something else) but do not connect to PZEM logic because this will result in a big flash (kaboom!Please be careful because the wiring between the 10 Ampere models with 100 Amperes is different, if a short circuit or a short circuit can occur in the electrical network.
