Connecting inexpensive edge hardware to robust cloud architecture is the foundation of modern engineering projects. The ESP32 microcontroller has become a staple for developers due to its integrated Wi-Fi capability and low price point. However, capturing data locally on your workbench is vastly different from streaming data securely to an enterprise cloud system. While this tutorial will help you build a functional prototype on your workbench, companies looking to securely deploy thousands of these IoT nodes across a smart factory often team up with a Microsoft solutions partner to architect a highly scalable and secure Azure environment. For our purposes today, we will focus on bridging the gap between physical hardware and the cloud by setting up a reliable telemetry pipeline. Prerequis ...
Picture this: a family pulled over on the side of a road somewhere in rural France, a massive paper map spread across the car hood, everyone arguing about which way is north. The guidebook they bought three months before leaving home has no idea if the restaurant they're looking for is still open. Or still in business. Or even on that street anymore. That was travel not so long ago. A lot of hoping, a lot of guessing, and occasionally a very patient local who spoke just enough English to point you in the right direction. That world is barely recognizable now. Booking a Trip Used to Be Its Own Ordeal Before the internet reshaped everything, planning travel meant working through a travel agent or spending serious time on the phone tracking down reservations. Agents were genuinely useful peop ...
Hello friends! How are you today? Today we're going to discuss a project that is interesting and also useful in our everyday life. You see QR codes almost everywhere, right? They are printed on almost every product's package, leaflets, newspapers, and brochures. Perhaps, you often use QR code scanners on your mobile device. What about making such a program by yourself? Yes! That is exactly what we are going to do today. We will make a QR code scanner using the ESP32-CAM. For image processing, we will use the OpenCV library. If you’ve ever wanted to create a real-time QR code scanner using a low-cost, wireless camera module, you’re in the right place. In this tutorial, we’ll walk through setting up an ESP32-CAM to stream video and using OpenCV to detect and decode QR codes in real time. Int ...
Hello, dear tech savvies! We hope everything is going fine with you. Today we’re back with another interesting project. Do you ever wonder how amazing it would be to have a text reader that would be able to read texts from pictures and videos? Think about a self-driving car that can read the road signs meticulously and go to the right direction. Or imagine an AI bot that can read what is written on images uploaded to social media. How nice it would be to have such a system that will be able to read vulgar posts and filter them even when they are in picture format? Or imagine a caregiver robot that can read the medicine bottle levels and give medicines to the patients always on time. Now you understand how important it is for AI solutions to recognize texts, right? Today, we are going to do ...
Hello friends. We hope you are doing fine. The world is full of colours. Isn’t it? We humans can see and differentiate the colours very easily. But teaching robots and AI apps about colours is a real challenge. With the advancement of computer vision and embedded systems, this task has become easier than before. Today, we are going to make an RGB colour identifier using the ESP32-CAM. This project combines the power of OpenCV with the ESP32-CAM module to create a simple but effective system for detecting and tracking basic colors in real time. System Architecture 1. Overview This system consists of an ESP32-CAM module acting as a live-streaming camera server and a Python-based computer vision application running on a remote computer. The Python application fetches images from the ESP32-CAM ...
Hello friends. We hope you are doing fine. Today we are back with another interesting project. It is based on the image processing technology. Developing efficient and cost-effective solutions for real-time applications is becoming increasingly important in the area of embedded systems and computer vision. This project makes full use of ESP32-CAM. ESP32-CAM is a compact and AI-enabled microcontroller with built-in Wi-Fi capabilities. We will create a real-time face detection and counting system. The ESP32-CAM serves as the core of the system. It captures high-resolution images at 800x600 resolution and hosts an HTTP server to serve individual JPEG images over a local network. The device’s efficient JPEG compression and network capabilities ensure minimal latency while maintaining high-qual ...
Imagine a real-time object counting system that is budget-friendly and easy to implement. You can achieve this goal with an ESP32-CAM. Today we will build an ESP32-CAM Object Counting System. This project is a combination of the power of embedded systems and computer vision. The main processor of the system is ESP32-CAM, a budget-friendly microcontroller with an integrated camera. This tiny powerhouse captures live video streams and transmits them over Wi-Fi. On the other side, a Python-based application processes these streams, detects objects using image processing techniques, and displays the count dynamically. Whether it’s tracking inventory in a warehouse, monitoring traffic flow, or automating production lines, this system is versatile and adaptable. You can implement this project wi ...
Welcome to the next tutorial in our Raspberry Pi 4 programming course. In the previous tutorial, we learned how to automate your home with a Raspberry Pi and Bluetooth Low Energy. We found that using a Raspberry Pi 4 and Bluetooth Low Energy (BLE), users may command their household appliances from their smartphone or a web interface, and the Pi 4 will carry out the commands. This allows for a versatile and adaptable method of managing lights, thermostats, and smart plugs. However, this Internet of Things (IoT) project aims to create a real-time Raspberry Pi weather station that displays the current humidity, temperature, and pressure values via an LCD and an online server. With this arrangement, you can track the local climate from any location in the globe over the internet and see what t ...
