Lenovo ThinkCentre M73 IoT Project Computer – Raspberry Pi Replacement

I suppose that in the implementation of IoT projects, we have two options for our servers, On Premise (Local Installation) or On Cloud (Hosted on the Internet), both have their advantages and disadvantages, but today we will talk about Local applications for our projects. For our local projects, I suppose that we implemented the world-renowned…

Download Lubuntu Virtual Machine (PDAControlMV) IoT in VirtualBox # 1

Virtualization is one of the most used methods to facilitate the compatibility of Software or simply the test of other Operating Systems, technically it is an operating system within another. I have tried for a long time Oracle VirtualBox is one of the most used virtualization software for x86 / amd64 architectures allowing virtualization. FreeBSD…

Basic Modbus RTU Master RS485 Test with ESP32 + XY-K485 + PZEM-016 (without libraries)

In this opportunity we will carry out tests and explanation of the Modbus RTU protocol implemented in ESP32 requesting data from the Single-phase consumption meter PZEM-016. The intent of this tutorial is: 1. Explain in a simple way the creation and operation of an industrial protocol, in this case the Modbus RTU protocol used and…

Review Dragino LoRaWAN RS485 to LoRaWAN RS485-LN Converter #8

I present the Dragino RS485-LN is an RS485 to LoRaWAN converter, a few months ago I ordered a couple of modules for testing. This converter would allow monitoring and controlling devices over long distances, adding the versatility of the RS485. Characteristics LoRaWAN Class A and Class C protocol (default Class C) Frequency bands: CN470 /…
