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 in…

Create Account in IoT Platform Ubidots

We have tested a wide variety of IoT platforms in this opportunity we will create an account on the platform Ubidots, this initiative was born to facilitate the connection of devices applied to the industrial and health. To highlight the large number of available devices (libraries and integrations) to connect with ubidots. Ubidots has 2…

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”,…

Electric Consumption with Meter CHINT (pulses) + ESP8266 & Matrix led MAX7912

This time we will return to an interesting project, the measurement of electrical consumption in an invasive way with a CHINT DDS666 Meter Mono phase, technically it is a residential or residential meter that we have already presented in previous tutorials, finally I will finish what I started more than a year: Warning: Caution is…

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…
