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…

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…

Manage 100 devices in Ubidots Apps, Organizations, Roles and Users

In this opportunity I have decided to test the practicality of the IoT platform Ubidots for user management in the case that it has many devices for several organizations or companies under the same Ubidots platform. More information: ubidots.com In previous tutorials we made the creation of a device configuration and design of a dashboard.  In previous tests…
