Meter PZEM-004T with Arduino ESP32 ESP8266 Python & Raspberry Pi

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. For a long time I wanted to try the PZEM-004T of Peacefair, I bought my meter…

How to find IP addresses of Ethernet devices?

In this opportunity we will address a problem that has happened to us when we need to obtain the IP address of an Ethernet device, it can be a PC, Smartphone, PLC in our case it can be an Arduino with shield ethernet, ESP8266 or ESP32. If we do not have the possibility to see or know…

Electricity consumption meter Peacefair PZEM 004 + ESP8266 & Arduino Nano

For some time I wanted to buy a single-phase electricity consumption meter, a few months ago I got Peacefair Reference PZEM-004 meter, its price seemed affordable, it has the advantages of being a non-invasive meter in the electrical circuit and has a communication protocol to request data such as Active Instantaneous Power “kW”, Voltage “V”,…

Test Module SD / MicroSD via SPI For Arduino & ESP8266

In this opportunity to test an SD Module and MicroSD with Arduino and ESP8266, in advance thanks to ICStation.com. We will not do a detailed tutorial on introduction to SD since there is already great documentation regarding the subject in intenet, but indicate the applications available for these modules. I introduce the SD module and Micro…

Installation Arduino IDE & Boards ESP8266 in Lubuntu

To avoid losing synergy in our tests in Arduino IDE, this time we will install Arduino IDE in our new operating system lubuntu “linux” and we will configure the boards to program the ESP8266. Installation Arduino IDE, Haste the current version 1.8.3. Installation of Boards libraries and examples for ESP8266. Tutorial Recommended: Full migration to…

ESP8266 program with Arduino IDE in 5 minutes

This ESP8266 default module that works by AT commands, thanks to the contributions of the community has made integration with Arduino IDE. This module (ESP8266) integrates the capabilities of an Arduino + Wifi (Ethenet) and easily the perfect combination for more or less one dollar, just personally I use in my applications in industrial integration,…
