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…

Modbus TCP/IP Slave Gateway to MQTT – ESP32 V.1

It’s been a while since I made a video or posted anything for PDAControl. I’ve actually been busy with other things and decided to get back to testing. I think the ESP32 is the quintessential microcontroller for testing; it has great features and I feel comfortable with it. There are other alternatives, which I might…

Easy Installation of Node-RED on Raspbian and Linux OS

For some time we have carried out a lot of tests with the Node-RED platform. This time we will try a method for installation established on the official website, which I consider the easiest way to install this platform in Linux operating systems (Ubuntu), emphasizing in this case Raspbian OS for Raspberry Pi. Recommended Tutorials…

Integration http JSON Node-RED (Raspberry Pi) with PowerPDU 4C from Netio # 002

A few ago we made the review of the Netio PowerPDU 4C a Power Socket, it is an Intelligent Socket which allows Iot and M2M integrations in a very easy way. Following the complete review of the Netio PowerPDU 4C, it has a lot of interesting features for measurement and control. In this tutorial we…

Review Module ESP8266 with 4 Relay & Node-RED from ICStation.com

I have seen a large number of applications of ESP8266 modules controlled loads using Reles, it would take time to really design from scratch, so thanks to ICStation.com I have received an ESP8266 module with 4 outputs to Relay. ICStation.com ESP8266 WIFI 4-Channel Relay   ESP8266-01 and N76E003AT20 It uses an ESP8266-01 module additionally uses…

Installation Node-RED on Windows

We have used Node-RED in a large number of applications and have installed it in several operating systems and devices, since it is the tool for connecting applications par excellence. This time we will install Node-RED on a Windows 7 Ultimate operating system, in a few steps, I assume that this method should work on…

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…
