In our day-to-day life, huge amounts of waste are generated in homes, streets, offices, and public places. But the real problem is not just collecting the waste; it is separating it correctly. When biodegradable waste like food waste and leaves gets mixed with non-biodegradable waste like plastic bottles and metal cans, recycling becomes difficult and environmental pollution increases. Manual…

Many visually impaired people identify currency notes by touching them. But as people grow older, their touch sensitivity may gradually decrease, making it difficult to recognise the correct denomination accurately. Imagine an elderly shopkeeper in a small roadside store who has weak eyesight and struggles to identify the money given by customers. In such situations…

If you are working on IoT projects, you already know the importance of an M2M IoT SIM card for remote monitoring and tracking. For those who are new and wondering why you need a special M2M SIM card when you can just use your normal SIM card, here are two strong reasons to consider one.

Cost: If you are running a…

Think of a busy road where hundreds of riders pass every minute, some wearing helmets, many not, and imagine trying to monitor all of them manually. It’s almost impossible to keep track in real time. Now imagine a small device quietly watching the scene, capturing an image with a single trigger, and instantly telling you whether safety rules are being followed. That is exactly what this ESP32-…

This tutorial shows you how to build a real-time object detection system using the ESP32-CAM module and the CircuitDigest Cloud Object Detection API. The system captures an image on button press, sends it to the cloud via wireless or internet connection, retrieves the identified objects with name(s), how many there were and how confident (how much certainty the algorithm has) of the object…

Nowadays, automation has become a common part of our daily lives. From simple tasks like operating a coffee machine to creating code for complex applications, many processes are now automated. However, most systems used for controlling devices depend on internet connections, mobile applications, or cloud platforms. In many places, internet availability may be poor or…

Nowadays, everything is rapidly transitioning into the digital world, from the way we communicate to how industries operate and services are delivered. Traditional methods that once relied on manual processes are now being replaced by smart, automated, and interconnected systems. Building an automated attendance system using ESP32-CAM is a practical, affordable way…

We use WhatsApp almost every day so much that it has become an unavoidable part of our routine. From a simple “good morning” message to a friend to a “good night” text to family, most of our daily communication happens through it. Beyond just messages, we constantly share moments from our lives by capturing photos on our phones and instantly sending them to others.…

With the rapid growth of IoT-based monitoring systems, staying informed about what’s happening in real time has become extremely important. Whether it’s detecting an intruder, monitoring equipment, or tracking activity, users need instant alerts without constantly checking dashboards or screens. Email notifications offer a simple and reliable way to receive detailed…

In our everyday lives, environmental conditions like temperature and humidity can have a big impact, whether it’s in your home, office, greenhouse, or server room. Imagine leaving your room for a few hours and suddenly discovering that the temperature had got too high or the air had become too humid. Keeping track of these changes in real time can be challenging,…

In recent years, the demand for smart security and automated monitoring systems has increased significantly due to growing safety concerns and the need for real-time surveillance. Traditional security systems often require continuous human supervision, which can be inefficient and time-consuming. With the advancement of embedded systems and Internet of Things (IoT)…
