The term internet of things was coined only in 2008, but within the next 10 years (in 2018) there were already more than 7 billion IoT devices connected to the internet, and the number is set to increase exponentially. IoT has enabled multiple inter-connected devices to sense and transfer data wirelessly over the internet to provide vital data and control in areas like Home automation, Location tracking, Asset monitoring etc..
This section provides a wide variety of IoT Projects with complete resources including circuit diagram and code, allowing you to build and test your own IoT applications. It also discusses the recent IoT Technology Trends and keeps you updated with the latest IoT News.
Espressif Systems has officially started mass production of its new ESP32-S31 wireless microcontroller, making it available to developers and manufacturers worldwide. The latest addition to the ESP32 family is built for demanding AIoT applications, combining faster processing, modern wireless standards, and multimedia support in a single chip. With production now underway, the ESP32-S31 is…
Chennai-based fabless semiconductor startup Mindgrove Technologies has teamed up with ed-tech company AtumX to launch AGNI, a developer board built around an indigenously designed chip, aimed at government school classrooms. The initiative marks one of the first attempts to put a domestically designed SoC directly into the hands of students rather than professional engineers.
The…
We can see wall-climbing robots from hobby-level to serious problem-solving ones that are used for inspection, surveillance, cleaning, etc. When we generally talk about robots, a robot can be a firefighting robot, a human-following robot, a self-balancing robot or can be of any type that has some specific features or solves a specific kind of problem. If we talk…
In modern day, the need for surveillance systems is increasing rapidly. We have a lot of recognized brands that offer such solutions. But can we extend the capabilities of a $5 ESP32-CAM module to build something similar?In this project, we are going to build an AI-Based No Parking Alert System using ESP32-CAM, in which, if someone parks their vehicle in front of the…
Researchers from the Pennsylvania State University have developed a paintable on-skin dry electrode that sticks comfortably to the skin and reads biological signals with impressive stability. Because the sensor starts as a liquid paint, it flows into the microscopic lines, wrinkles, and pores of your skin before it dries. This creates a perfect, seamless bond that…
"Where did my pet go?" If you have a pet, you've probably asked this question at least once. One moment they're playing happily in front of you, and the next... they're gone! Maybe they saw a butterfly, started chasing a bird, or simply decided to go on a little adventure without telling you. A GPS pet tracker solves this problem before it turns into a crisis. Now…
This tutorial shows us how to build our own functional DIY ESP32 metal detector from scratch using an affordable Wi-Fi enabled microcontroller, a handful of easily available electronic components, and a simple, hand-wound copper coil. Instead of relying on expensive, specialised sensors or complex industrial circuits, this PI metal detector circuit project uses…
With football fever reaching its peak, DHK DUDE from youtube built this pocket-sized, real-time World Cup score gadget for his desk. Powered by a Wemos D1 Mini microcontroller, this custom IoT gadget utilizes built-in Wi-Fi to seamlessly connect to the internet, fetching live match telemetry, group fixtures, and team data directly through web APIs. Like every maker…
In this tutorial, we’re going to learn how to send data from an ESP32 to Firebase Realtime Database. We are using ESP32 Firebase Google as our cloud platform. A lot of cloud-based IoT projects on YouTube / GitHub / similar platforms using ESP32, ESP8266, UNO R4, or similar microcontrollers use Firebase as the cloud platform. And this guide covers the complete ESP32…
We're all familiar with live GPS tracking; it tells us where a vehicle or device is right now. But what if the system could do more than just show the location? That's where geofencing using IoT comes in. Imagine receiving an instant alert the moment a vehicle leaves home, reaches college, enters the office, or moves into a restricted area. Instead of…
Imagine you've just sent a parcel through a courier service. As soon as it leaves your hands, you start wondering what is happening to it. Is it being handled carefully? Has it been dropped or damaged? Is it still on the right route? Will it reach the destination safely and on time? The truth is, once we send a parcel, we have very little idea about what happens…
This DIY tutorial is all about making our home lighting smart and fun without any complicated steps. We can connect a standard 12V LED strip to a tiny wi-fi chip and build our own ESP32 WLED controller custom smart lighting system, which can be completely controlled from a smartphone or computer.
This DIY ESP32 based WLED controller…
