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…

Tutorial Platform IoT Ubidots & ESP8266 + Sensor DHT11

  This time we have tested the platform Ubidots, is an IoT platform dedicated to the collection and display of data, creating colorful graphics. For our test we will use the Module ESP8266 and a DHT11 sensor to measure the temperature / relative humidity and later visualize it.  Official Website: Ubidots Initially Create an account…

Introduction Platform Mongoose OS

For a long time I wanted to test Mongoose OS, this time we will make a brief introduction and installation in a Linux operating system “lubuntu” Ubuntu/Debian. Mongoose OS is an open source operating system for Internet of Things (IoT) and low power microcontrollers such as ESP32 , ESP8266 , TI CC3200, STM32  license Available under dual GPLv2 / business…

WifiManager + Emoncms (OEM) with ESP8266 (Temperature) #1

The following implementation using an ESP8266 module and a temperature sensor ds18b20 allows the configuration and sending of data to Emoncms without requiring to modify or edit a line of code, facilitating the creation of parameterizable applications. After testing the Wifimanager libraries, which allow an agile configuration of the network credentials and additionally allow to…

Introduction library WifiManager

The main disadvantage is to configure the network credentials in a esp8266 without requiring to modify and download the firmware again, I have tested with several methods to dynamically store the SSID and  PASSWORD of a network. In the case of the esp8266 programmed in Arduino IDE for some time I have seen a proposal…

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…

Introduction Plataform InitalState & ESP8266

This time we tested the Initialstate platform, is an IoT platform dedicated to the collection and visualization of data, creating colorful graphics. For our test we will use the ESP8266 Module and a DS18B20 Onewire sensor to collect temperature and then visualize it. Safely send time series data to your account from sensors, devices, software…

ESP8266 & Public MQTT Broker mosquitto.org & Node-RED

In the last tests we have taken the MQTT protocol since it has taken great strength the last few years and we think it is thanks to its simplicity, security, practicality and very lightweight projects IoT and M2M applications. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Internet…

ESP8266 & Public Broker MQTT mosca.io & Node-RED

The MQTT protocol has taken great strength in recent years since it is simple, safe, practical and lightweight perfect for IoT and M2M applications. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Broker for tests, are available to connect from any MQTT client in this case will use…
