MQTT Toolkit for IOT Sensors INTRODUCTION Ready for Industrial Internet of things (IOT) applications, WiLow IOT sensors integrate natively MQTT (Message Queuing Telemetry Transport) data frame, a lightweight and open-source (OASIS & ISOIEC 209222016 standards) Internet of Things protocol.

Sep 24, 2020 In this demonstration, we show how you to build a low cost Industrial Internet of Things (IIoT) solution using GridDB on a Raspberry Pi 4 with a Node-Red flow that uses MQTT to read temperature sensor data from an Industrial Shields M-DUINO 21 Arduino PLC and then visualizes that data using Grafana.

You do not need to read the temperature directly from the device if you are using MQTT. Just enter your MQTT topic and send a static value After a click on the publish button those two values 30 and 70 will appear in your sensors for temperature and humidity.

1. Publish to your own publication. This involves creating your own Medium publiucation page that can be focused on whatever topic you want. You then craft content that will specifically be published on that page. This is the easiest way to get published right away.
2. Submit to other publications. This is when you write an article in the hopes of getting it published in another Medium blog. While this is a good way to tap into an established publication’s audience, it does mean you need to write an entire article beforehand with no guarantee that it’ll get published in the publication. Note, however, that if you do NOT get accepted into a publication, you can still put your article on your own page or publication you run.
