MQTT in ESP32 with ESP-IDF – ESP-MQTT & Node-RED

Normally if we look for tests with the ESP32 module and the MQTT protocol, they mainly use Arduino IDE for ESP32, there is no problem, but this time we will use espressif development environment “ESP-IDF” or “Espressif IoT Development Framework” for the ESP32 which has more advantages and features for more robust applications. ESP32 Module…

Review Module Wemos TTGO ESP32 + OLED V2.0 + DHT11

I present a TTGO ESP32 module, this device has caught my attention since it is very complete, I ordered one to the Banggood.com online store for testing, the interesting thing is the union of the well known ESP32 module, DHT11 Sensor (Temperature / Relative Humidity ), 0.96 inch white OLED display, charging circuit for Lithium…

Measurement Electrical consumption with Ubidots Industrial & ESP32 + PZEM-004T

On this occasion I have proposed to measure the electricity consumption of my entire house to make comparative estimates with the collection of my energy bill and analyze. On this occasion I will use the IoT platform Ubidots in its Industrial version, previously we had done tests with the educational version, but this industrial version has special…

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…

Arduino IDE for ESP32 modules

Given the great popularity of the ESP8266 programmed from Arduino IDE in great contribution by Ivan Grokhotkov thanks, Currently for ESP32 modules has been allowed to program them from Arduino IDE in collaboration with espressif, Although it is a project under construction so far the control of certain hardware is in the process of migration. Currently…

ESP-IDF for Modules ESP32 Complete Installation

This time we will install and configure  Espressif IoT Development Framework platform (ESP-IDF) from scratch, this is the official espressif development platform for the ESP32 modules. In previous tutorials we talked a little about the ESP32 that have Wi-Fi (2.4 GHz band) and Bluetooth 4.2 in a single module among other features. ESP32 eBox&Widora first review I took…

ESP32 eBox&Widora first review

More than a year ago Espressif released the long-awaited ESP32, these modules are low cost microcontrollers, low power consumption, Wi-Fi chip, Bluetooth and what is really amazing the Tensilica Xtensa LX6 dual-core microprocessor !!, another interesting fact has improvements in security and secure connections, is the successor of esp8266. Unlike ESP8266 espressif design the ESP32…

Update Ubidots Libraries V3.0.0 for ESP8266 modules

We have carried out a large number of integrations and tests with the Ubidots IoT platform, mainly with Espressif ESP8266 Modules. Ubidots platform IoT Create Account in Ubidots.com. In this new tutorial we will test the new version of the Ubidots library for ESP8266 V3.0.0. ESP8266 integrations with Ubidots I will list some of our…

Review Module RAK811 LoRa Node AT-Commands LoRaWAN # 3

Some time ago, in previous tutorials we have already determined some factors to choose the appropriate gateway (gateway LoRaWAN) for your LoRaWAN application, this tutorial was created gathering considerations before starting, with considerations scopes and concepts about LoRaWAN. Based on these considerations, a robust, powerful and functional gateway or gateway has been assembled according to…

Making Motherboard, Rapid Prototyping with JLCPCB.com

A colleague has designed a rapid prototyping system, mixing practicality with robustness in the assembly of DIY projects, integrating assembly of ESP32 modules, Arduino, Raspberry Pi, Lora I / O ADC, sensors and relays among other peripherals for external assembly. Initially, pcb’s were created in an artisanal way for tests, after tests it has been…
