Introduction: When “Smart” Meets a Dark Room

On 17 November 2025, I left a small restaurant in Nairobi after supper, ready for my usual night shift. I am one of those people who prefer to work when the world is quiet. I reached my rented room, opened my laptop, sat down, and then everything went off. Power gone. Again.

This has happened to me in South Sudan and in Kenya. In Juba, it was almost normal. Generators, noise, darkness, silence, repeat. In Nairobi, I expected things to be slightly different, at least in the building where I was renting. That night, the electricity did not come back. My laptop battery was low. My phone became my light, my modem, my office, my bank, my diary, my friend.

As I sat in the dark, using my phone as a hotspot to keep the laptop alive, I realised something. For many of us, that small smartphone is already our smart home, our smart office, and our smart bank. One device controls payments, messages, business, learning, and entertainment. That is when this big term, the Internet of Things, became personal once again.

We often imagine IoT as a luxury for people in rich countries. Yet I was in a dark room in Africa, relying on one “thing” connected to the internet to keep my life moving. That is IoT in its simplest form.

In this article, I want to explain the latest trends and opportunities in the Internet of Things and smart devices, using plain language, real African experiences, and stories from my own path from the Sobat River to Nairobi.

What Is the Internet of Things?

When I was a boy along the Sobat River, we monitored life using our senses. To know if the river was rising, we watched the water and listened to its sound. To check if a cow was sick, we looked at its eyes, movement, and appetite. To predict rain, we looked at clouds and wind. There were no devices, no apps, no dashboards. Only people, nature, and experience.

The Internet of Things is like giving eyes, ears, and a voice to physical objects, then connecting them to the internet so they can share what they see and hear.

In simple terms:

1. A “thing” is any physical object: a watch, a fridge, a car, a pump, a gate, a tractor, a light bulb, even a cow.
2. That thing has sensors inside it: to measure temperature, motion, sound, light, location, heart rate, water level, and so on.
3. It has software that can read and process the data from those sensors.
4. It has a way to connect to the internet: Wi-Fi, mobile network, satellite, or some other connection.

Once all that is in place, the object can:

• Collect data.
• Send that data to a phone, a server, or a cloud service.
• Receive commands.
• Sometimes act on its own, with little or no human input.

This is the Internet of Things. Ordinary objects become digital messengers.

Everyday Examples of IoT in African Life

You may already be using IoT without calling it by name.

Think about:

• A cheap internet camera in a small shop in Juba or Nairobi, sending video to the owner’s phone.
• A GPS tracker inside a boda-boda, a taxi, or a delivery bike.
• A pay-as-you-go solar system in a rural village, where the company switches the power on or off remotely, depending on payment.
• A smart meter for electricity that reports usage to the utility company without anyone walking to your house.

In my own life, simple smart devices have changed how I live and work:

• My phone acts as a portable office, with banking, communication, and writing tools.
• A Wi-Fi router reports errors and reconnects itself after many outages.
• Health apps on the phone quietly track my sleep and movement.

I grew up catching mudfish with simple tools, running from bullets, and surviving famine. Today I can sit in a room and see, through a small screen, what is happening across the world in real time. That is a very long journey in one human life.

The Surge in Smart Devices Around the World

Globally, the number of connected devices has been growing very fast. Analysts speak of tens of billions of IoT devices installed worldwide by the mid-2020s, up from only a fraction of that a decade ago.

The reasons are simple:

1. Hardware is cheaper. Sensors, chips, and small processors cost less than ever before.
2. Connectivity is more available. Wi-Fi, 4G, and 5G networks cover more places.
3. Cloud services are easier to use. You can store and process data online without building your own data center.
4. People demand convenience. Once people taste remote control, mobile payments, and automation, they want more.

For someone like me who remembers life with zero internet and no electricity, this sudden flood of connected devices feels almost like magic. Yet it is not magic. It is human design and engineering.

Consumer IoT: Smart Homes and Wearables

In many countries, smart homes are the first visible sign of IoT adoption.

Common devices include:

• Smart speakers that answer questions, play music, and control other devices by voice.
• Smart lights that switch on or off through an app or schedule.
• Smart locks and doorbells that show who is at your door and allow remote access.
• Smart cameras and motion sensors for security.
• Smart thermostats that learn your favourite temperature patterns.

From my room in Nairobi, when I watch videos of these homes, they look like science fiction compared to my childhood huts on the Sobat River. At the same time, the gap is not as big as it seems.

Give one determined African a smartphone and mobile internet, and you already have:

• A remote control for bank accounts, electricity tokens, and bills.
• A portable office for working with clients worldwide.
• A media center for learning and entertainment.

In the health space, wearables are another strong trend:

• Fitness trackers and smart watches count steps and measure heart rate.
• Some devices monitor sleep patterns, stress levels, and blood oxygen.
• Advanced devices can send alerts when they detect dangerous patterns.

I personally do not walk around with the latest smartwatch all the time. Yet my phone still tells me how long I have sat typing, and when I should get up and move a bit. That small reminder can protect my health more than any long lecture.

Now imagine similar devices helping elderly people, patients with chronic diseases, and pregnant women in remote areas. The potential is huge.

Business and Industrial IoT: From Factories to Farms

Businesses are also adopting IoT to improve how they operate. This is often called Industrial IoT.

Examples include:

• Sensors on machines that measure vibration, heat, and pressure, warning engineers before a breakdown.
• GPS trackers on trucks that show routes, speed, fuel usage, and stops.
• Environmental sensors in warehouses that monitor humidity and temperature for medicines or food.
• Cameras and scanners in shops that measure customer traffic and product movement.

In humanitarian and development work, I have seen smaller versions of the same idea.

Imagine:

• A health organisation tracking the temperature of vaccine fridges in rural clinics.
• A water project team monitoring boreholes and tank levels from a central office.
• A food security project checking moisture levels in soil across demonstration farms.

Instead of waiting for someone to call and say, “The fridge failed yesterday,” or “The pump broke last week,” you can receive an alert early and act in time. That difference can save medicine, fuel, water, and, ultimately, lives.

5G and the Push for Better Connectivity

IoT needs affordable and reliable connectivity. In South Sudan, I have sometimes spent more on internet than on food. In Nairobi, monthly Wi-Fi can still become the biggest bill for a writer who lives online.

Technologies like 4G and 5G aim to help by providing:

• Higher speeds.
• Lower delay between sending and receiving information.
• Capacity to connect many devices at once.

With strong mobile networks, it becomes easier to:

• Control machines and vehicles remotely.
• Stream high-quality video from cameras and drones.
• Receive fast feedback from sensors in clinics, farms, and factories.

Of course, many African towns still struggle with weak networks, long outages, and high data costs. I know this from my own experience of sudden blackouts and internet failures. Yet even now, small pilot projects in rural areas are using mobile networks to send sensor data from water systems and solar installations.

The lesson here is simple: for IoT to serve Africans well, we must keep demanding fair prices, better regulation, and real investment in infrastructure. Technology without access is only theory.

Edge Computing: Bringing Intelligence Closer to the Ground

The classic internet model sends data from devices to faraway servers, where heavy processing happens. That is good for some tasks, but not all. For many IoT applications, sending everything to the cloud is too slow, too expensive, or too risky.

Edge computing is a solution that brings processing closer to the source. Devices, or small local servers, do more of the thinking themselves.

Examples:

• A clinic gate camera that recognises faces and suspicious activity on-site, and only sends alerts and summaries to the cloud.
• A small device in a truck that analyses speed, harsh braking, and cornering in real time, and buzzes the driver when behaviour becomes unsafe.
• A solar pump controller that studies local water usage, panel performance, and tank levels, then adjusts pumping automatically.

This method:

• Reduces bandwidth use and data costs.
• Keeps sensitive raw data local, improving privacy.
• Shortens reaction time where every second counts.

For Africa, where connectivity can be unreliable, this is good news. Devices that are smart at the edge can continue doing useful work even when the signal disappears for hours.

Artificial Intelligence Inside Everyday Objects

Artificial intelligence is another building block of modern IoT systems. AI helps machines learn from experience and handle tasks that used to require human judgement.

In IoT, AI can:

• Find patterns and detect unusual behaviour in sensor data.
• Recognise faces, objects, and scenes in images and videos.
• Understand spoken commands and answer questions.
• Predict failures before they happen.

Voice assistants, predictive maintenance systems, fraud detection tools, and personalised recommendation engines all rely on AI.

In African settings, AI combined with IoT could support:

• Smart irrigation systems that decide when to water crops based on soil moisture, weather forecasts, and crop type.
• Flood early warning systems combining river sensors, rainfall data, and historical patterns.
• Health triage tools that read simple symptoms collected by devices and guide patients on the next step.

Here my own life philosophy, M = {B, D²}, becomes very useful.

• Being: who we are as Africans, our values, culture, and real needs.
• Doing squared: what we do repeatedly and intentionally with these tools.

If we only import devices and software without aligning them with our identity and purpose, we will lose ourselves. If we connect our being and our doing wisely, then IoT and AI become tools that support a meaningful life instead of replacing it.

New Opportunities in IoT and Smart Devices

The growing IoT field offers many opportunities for innovation and value creation, especially for people and organisations that understand local problems.

Some areas with strong potential:

1. Health and Telemedicine

Think of:

• Remote monitoring of patients with chronic diseases using simple wearables linked to local clinics.
• Smart pill boxes that track when tablets are taken and send reminders.
• Connected ambulances that share vital signs with hospitals before arrival.

In regions where distance and poor roads cause many deaths, such solutions are more than gadgets. They can save lives.

2. Water, Sanitation, and Hygiene (WASH)

Organisations like Yo’ Care South Sudan and others working in WASH often manage many boreholes, tanks, and latrines at once. They rely on human reporting, which is slow and sometimes inaccurate.

IoT can help by:

• Measuring water levels in tanks and reporting when they drop too fast.
• Monitoring handwashing stations in schools and health facilities.
• Tracking chlorine use and stock levels to ensure safe water.

This turns scattered, manual data into continuous, real time understanding of what is happening on the ground.

3. Agriculture and Food Security

Food insecurity has walked alongside me since childhood. I know the pain of empty stores and thin cattle. IoT can support:

• Soil moisture sensors guiding irrigation for smallholder farmers.
• Low-cost weather stations giving local forecasts instead of general national ones.
• Livestock trackers reducing theft and helping pastoralists manage herds more effectively.

Instead of telling farmers “modernise,” we give them timely, accurate information they can trust. That is respect.

4. Urban Transport and Safety

In growing cities:

• Smart traffic lights and road sensors can ease congestion.
• Connected public transport can show real-time bus locations.
• Smart streetlights and community security cameras can improve safety if regulated properly.

These tools can make life less stressful and more predictable for everyday citizens.

Jobs, Careers, and Business Models Around IoT

IoT is not only about devices. It creates jobs and business ideas.

Some examples:

1. Installation and Maintenance

Every sensor, camera, meter, and gateway needs:

• Correct installation.
• Occasional repair.
• Software updates.

Young people who learn to install and maintain IoT systems will find steady work. Think of solar installers, but for sensors and smart devices.

2. Local Integrators

Most IoT platforms are designed globally. Local companies can stand in the middle and:

• Bundle devices and services into simple packages for clinics, schools, farms, and shops.
• Build dashboards that show local data in friendly formats.
• Train clients and provide ongoing support.

3. Data and Advisory Services

Data itself has little value if nobody interprets it. People with skills in data analysis, business, and communication can:

• Offer monthly reports for organisations using IoT.
• Provide recommendations based on trends and patterns.
• Help decision makers act on the information.

4. Education and Storytelling

As a writer and teacher, this is where I stand. There is a real need for:

• Plain-language articles and books explaining IoT to non-technical readers.
• Courses and workshops teaching communities how to benefit from smart devices safely.
• Stories that show both the promise and the danger of these tools.

Every new technology needs translators between the engineers and the people. You can be one of those translators.

Security, Privacy, and the Dark Side of “Smart”

When everything is connected, everything can be attacked or misused. We must face this truth directly.

Common risks include:

• Hacking of poorly secured cameras, sensors, and routers.
• Theft of personal data, including health and location.
• Use of IoT devices as part of large cyberattacks.

I have seen how simple accounts are hijacked and used for fraud. Now imagine what could happen if power grids, water plants, or hospital devices are not well protected. The cost would be very high.

Security must be built into IoT projects from the beginning:

• Strong passwords and authentication methods.
• Encryption of sensitive data during storage and transmission.
• Regular updates and patches.
• Clear rules about who can access what.

Privacy is just as important. IoT collects sensitive information about people’s movements, habits, health, and finances. We must ask:

• Who owns this data?
• For how long is it stored?
• Can people choose to say no?

Respecting privacy is respecting human dignity. Without that, IoT can quickly become a new way to control people instead of serving them.

Another risk is overdependence. That dark night when the power went off in Nairobi taught me how fragile my digital life is. If your clinic cannot open because a connected lock is down, or your home is dark because a smart system crashed, then technology has gone too far. We must keep simple, manual backups where life and safety are concerned.

How Aspiring African Writers and Entrepreneurs Can Join the IoT Movement

If you are an aspiring African nonfiction writer, creator, or entrepreneur, you might think IoT is too technical. I want to tell you clearly: you do not have to be an engineer to participate.

Here are some paths you can consider.

1. Learn the Basics

• Study simple explanations of IoT, smart devices, and sensors.
• Watch beginner tutorials on small boards like Arduino or Raspberry Pi, if you are curious.
• Understand how data moves from a device to a phone or server.

2. Become a Storyteller Around Technology

• Write articles explaining IoT examples in your own community.
• Translate technical language into stories ordinary people understand.
• Help both users and leaders see where IoT truly helps and where it can harm.

3. Become a Problem Finder

• Visit clinics, schools, farms, and markets.
• Listen carefully. What do people complain about again and again?
• Ask: Could a simple sensor, a connected meter, or a tracking device help here?

Many great IoT ideas begin with listening, not coding.

4. Partner With Technical People

• You bring knowledge of people, language, and local conditions.
• They bring coding, electronics, and engineering.
• Together, you create solutions that actually fit real life.

5. Start Small and Practical

• Pick one small problem, such as monitoring a farm tank or tracking room temperature in a medical store.
• Use simple, affordable hardware for a pilot.
• Measure results honestly and adjust.

A simple, working solution that saves a small clinic money and stress is worth more than a grand theoretical plan.

Final Thoughts: From Things to Meaning

At first, the Internet of Things sounds like a cold phrase. It talks about things, not people. Yet my own journey has shown me that behind every device, there is a human story.

I have walked barefoot to rivers, eaten mudfish, escaped bullets, and faced hunger. Today, I rent a small room in Nairobi, connect a laptop to a phone hotspot, and speak to the world. Somewhere between those two worlds, IoT appeared.

Smart devices can:

• Improve health care in remote places.
• Protect water sources and crops.
• Make transport safer and more predictable.
• Create new jobs and businesses.

They can also:

• Increase surveillance and reduce privacy.
• Deepen inequality between those who have access and those who do not.
• Make us too dependent on systems we barely understand.

My belief is simple. Technology should serve meaning, not the other way around. That is why I hold firmly to M = {B, D²}.

• Being: knowing who you are and what you stand for.
• Doing squared: acting with intention, again and again, in line with that identity.

If we stay rooted in our values and clear about our purpose, we can use IoT and smart devices to extend our reach without losing our soul.

So as you read news about new sensors, wearables, and smart homes, remember this: the real question is not how many devices are connected. The real question is what story those devices are helping you write.

Are they leading you toward a life of meaning, dignity, and service to others, or are they just adding noise to an already noisy world?

That choice is still in our hands.
