Recommended Tutorial: Peacefair Power Meter PZEM 004 + ESP8266 & Arduino Nano This version works exactly the same as the PZEM-004 version, its communication protocol is the same, it has the advantages of being a non-invasive meter in the electric circuit, the perfect size for small spaces, it has the 4 variables available Instantaneous Active Power “W”, Voltage “V”, Amperage “A” and Active Power Accumulated “Wh”. I placed my order at Banggoodand after 7 days arrived my new meter and its respective CT or current transformer.Īs mentioned before size is a great advantage, for low space projects, or small encapsulations. This meter has great benefits in applications of measurement of residential electrical consumption at the DIY perfect for basic projects of analysis of electricity consumption at a low scale, perhaps at the residential level or home level and is perfect for integrations with IoT platforms, for example: Emoncmsof the OpenEnergyMonitor Project. In this opportunity we will collect tests with my new electric consumption meter PZEM-004T, making integrations with some of the most known hardware platforms ESP8266, Arduino Nano, ESP32, Arduino UNO + Shield Ethernet W5100 and Python in Raspberry Pi.įor a long time I wanted to try the PZEM-004T of Peacefair, I bought my meter in the well-known Online store, at a very affordable price, it is impossible not to buy it.
