When an ageing parent falls at home, the immediate injury is usually only half the danger. The real danger begins during the critical time they spend waiting on the floor for help. Lying immobile for extended periods can rapidly lead to severe dehydration, hypothermia, and muscle breakdown, even in homes where family members are regularly around. Expecting an injured…

Almost every kitchen has a pressure cooker, but we've all had trouble handling them. It’s too easy to turn on the stove, get distracted by work, TV, or housework, and forget to turn it off. If we miss a whistle count, food gets burned, utensils get spoiled, and there are chances of accidents in the kitchen. But then again, being in the kitchen and manually counting…

Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the…

"Is it going to rain, or should I leave the windows open?" we would have asked ourselves numerous times. Now the weather is clear, but sometimes the rain will suddenly start pouring. The standard weather forecast application may give you accurate forecasts near the airport or other places, which are kilometres away from us, but it will not give us accurate forecasts…

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…

Everybody likes weekends. On weekends, you often drive with your family to crowded places like malls, theme parks, or circuses for outings and relaxation. But then comes one of the most frustrating parts of the trip: searching for parking. Sometimes, finding a parking space feels even harder than waking up early in the morning.Even if there is a security guard or…

Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat breakfast properly. Then where do we find the time to clean our homes? Even when we clean, because of laziness or lack of time, we often throw all waste into the same bin without separating biodegradable and non-biodegradable waste. This creates a…

What if a device could see the world the same way humans do, seeing objects, recognizing them, and understanding what they are in real time? Just like our eyes capture visuals and our brain instantly processes them, from bottles and phones to people and everyday items. It will be pretty cool, right? That is exactly what this Raspberry Pi object detection project demonstrates. You can build a…

As adults, it is our duty to follow traffic rules, and the most important rule is to wear a helmet while riding a two-wheeler and not to cross the speed limit. It's not a rule, but it's also for safety. Now, let’s think from the traffic police officer’s side. Their duty is to monitor traffic and check whether everyone is following the rules, but it is quite difficult for a traffic officer to…

Imagine driving into a crowded parking area and not knowing whether a space is available or not. This project solves exactly that problem by building a smart, automatic parking space detection system using the ESP32-CAM and the CircuitDigest Cloud API. With just a button press, the device captures a real-time image of the parking area and sends it over the internet…

When we see movies, we often see scenes where a villain uses a gun with a face detection system that automatically targets a person accurately. It may look like a very complex technology that is difficult to build on our own, right? Not anymore.  Building a face detection system using a Raspberry Pi might sound like something out of a Hollywood thriller, but it…

Have you ever watched a movie where a system instantly detects a person’s face, like in security doors or smart targeting systems, and thought, “This looks too complex to build in real life?” It might seem like something only high-end systems can do, but the reality today is very different. With compact and powerful modules like the ESP32-CAM, building an ESP32-CAM…
