In my last article, I tried to give a gist of one of the many ways how a Secured IoT system could be deployed. In this article, I shall demonstrate another common way to secure your IoT Network by shielding it from the outer world.

I will also show, how web apps could interact with the MQTT broker which brings endless possibilities as raw sensor data could be accessed seamlessly in FrontEnd Apps.

The things I will be talking about are:

• WebSocket protocol support for the Broker
• Reverse Proxying the Broker

I will not be using something new, it’s the…

In my last article, I showed how we could build an IoT app without the Internet. It's a good exercise when you want to get started or do Rapid Prototyping without having any dependency on the Internet. One question that is always asked by the people evaluating the proof of concepts, is regarding Security. How have you secured your solution ? Most of the customers’ concerns when they are contemplating to introduce IoT into their business or product line are related to security. Be it device security or network security, having it on scale is very important. …

I hope you guys liked my last article. The intent was to show how easy was it to get started. I am not going to talk about real sensors or actuators until we have built our base understanding strong.

“The secret of getting ahead is getting started. The secret of getting started is breaking your complex, overwhelming tasks into smaller manageable tasks, and then starting on the first one.” — Mark Twain

I always like to break big problem statements into a chunk of smaller ones, which help me focus and then knock them down one at a time. …

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…

I have many people asking me how do I do Internet of Things (IoT) projects. The kind of people which ask me are from various different backgrounds like e.g. College grads, Mechanical engineers, Creative Tech designers, Computer Engineers and even Solutions Architects who have different domain knowledge. Personally, I think everyone is curious about the buzzword and since the market is flooded with devices like Alexa, Google Home and smartphones, people are keen to automate things or derive insights.

In this series, I wish to share with everyone some things for those who are curious to start or do something…

In this article, I will go through an application which monitors your incoming packages at your doorstep using AI.

Scenario

As we are mostly home, due to the current pandemic situation, we shop online for a lot of items from different e-commerce websites and the packages get delivered at our doorsteps. How cool would it be that, if you get notified instantly when packages get delivered to or removed from your doorstep? This is exactly what I will be covering in this article.

Motivation

My motivation for this project was 2-fold. Firstly, the idea came up when alwaysAI asked if I would…

Nvidia is one of the companies that is democratizing Machine Learning (ML) at the edge. This really excites me as an IoT engineer who wants to add ML capabilities to my applications e.g. ensure safety at an Industrial Plant to check for people in forbidden areas.

Nvidia has released Jetson and Xavier developer kits which are great for people who want to build really cool computer vision projects ranging from self-driving cars, robots, smart cameras and whatnot. The possibilities are endless. Huge shout out to pyimagesearch blog which has provided detailed setup instructions from time to time to get your…
