Integration Platform Ubidots with LOGO! Siemens using Node-RED
For some weeks I have done some tests with a LOGO! (logical module) from Siemens, for a few months I have seen that they use it in basic industrial applications, although I do not personally consider it 100% a PLC, it is easily integrated into monitoring and control applications for simple processes. You could say…
Introduction to Lora Server Platform IoT LoRaWAN
Loraserver is a project started in 2015, it is an open source LoRaWAN server, the project provides the components to create LPWAN networks based on LoRaWAN, it includes a user-friendly web interface and the gRPC and REST APIs, each component or module is configurable and they also allow exchange according to the needs of their…
Connection LOGO! 0BA8 Siemens Ethernet with Node-RED S7COMM Protocol
In this opportunity we will make an integration of our LOGO! from Siemens with Node-RED, the connection platform for devices and IoT applications par excellence. Recommended: Previous tutorials with LOGO! Normally the LOGO! are programmed with LogoSoft Software Logo! , its programming language are logical block diagrams. The LOGO! In addition to allowing load…
Meter PZEM-004 + Arduino Nano Modbus RTU (RS232) & Platform IoT Node-RED
Originally this test is performed in June 2018 in less than one year, for reasons of availability do not publish, technically just missing the documentation, then I will present the results, well they say there is better late than never. In this opportunity our PZEM-004 meter or it is also possible with our PZEM-004T communication…
Installation of Raspbian OS in Virtual Machine (Virtualbox)
For some years I was in doubt if I could run Raspbian OS, operating system for Raspberry Pi, on a normal computer. Five years ago there was an option using QEMU, it was the only method to run an operating system designed for ARM processors, at that time my attempts were unsuccessful. Currently on the…
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…
Quick test Amazon Echo Dot (Alexa): ESP8266 WEMOS – Relay 3v DFRobot – Emulating WeMo Switch
Some time ago I made a review of a smart speaker Echo Dot Amazon, Tutorial: Alexa Amazon Echo Dot First Steps and Configuration, this time adding an ESP8266 module Wemos version and a Gravity Relay module to 3v of the DFRobot Online Store, emulate a Wemo Belkin switch. I’m testing the alexa Skills that are…
Integration PLC Panasonic Device Types – Bulk upload devices with Ubidots
En In this opportunity we will carry out tests with a Programmable Logic Controller, in this case a PLC FP-X C14R compact Panasonic brand, we will control it from the IoT Ubidots platform. On this occasion we use 2 very interesting features of the Ubidots platform. Device Types: Creation of advanced properties for our devices….
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…
