IoT Hello World :)

5 min readJan 17, 2021

Every IoT project, big or small, consists of 3 main components namely the sensors, the actuators and the communication medium by which the things talk to each other also known as the control center.

In this article, I would like to demonstrate how we could simulate a sensor action, a control center and an actuation based on the sensor condition. I am therefore calling it a “Hello World” as this is what we try to do when we learn something new :)

Before we move any further, refer to my IoT device setup article to have the device ready for this tutorial.
