Introduction LoRa & Module RFM95 Hoperf

In this opportunity we will make a brief characterization about LoRa ™ and specifically Radio RFM95/96 manufactured by Hoperf Electronics. Since a couple of months ago, 2 modules arrived, initially I want to make an introduction on the subject that had been pending for a long time. Website: Hoperf Electronics Personally for a long time I…

Installation KiCad in Ubuntu and Windows

In certain projects we need to go from a schematic diagram to the manufacture of a PCB, there are a variety of platforms and Software for this task, for some time I have decided to adopt free software, in this opportunity I present KiCad. Oficial Website: KiCad Downloads: KiCad I have found this comparative table to…

Meter PZEM-004 + ESP8266 & Platform IoT Cayenne Mydevices

In this opportunity we will integrate our electric consumption or  active power meter , Pzem-004 of  Peacefair  with the IoT Cayenne mydevices platform using an ESP8266 module, later we will create a dashboard to visualize the 4 available variables such as active power, accumulated electric consumption, voltage and current. Previous Tutorials Recommended Introduction IoT Platform Cayenne mydevices…

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…

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…

Review Solar Panel 10W with Arduino and Node-RED

For a long time I had planned to make some application with photovoltaic panel or common solar panel, in this opportunity I have acquired a monocrystalline solar panel of 10w perfect to power the devices we use in our tutorials. Although this is in design, we will perform a meterological station – Gateway later, and…

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…
