The Internet of Things (IoT) is poised to reshape the world in 2025. With an estimated 18.8 billion connected devices worldwide, IoT is connecting everything from smart fridges to self-driving cars. Global spending on the Internet of Things (IoT) is projected to reach $1.1 trillion this year, underscoring its significant impact. These devices talk to each other, share data, and make our lives easier. Let's dive into what IoT is doing today, how it’s changing how we live, why it matters, and what the future holds.
What Is Internet of Things (IoT)?
IoT, or Internet of Things, is a network of devices linked to the internet. These devices have sensors, software, and connectivity to collect and share data. For example, a smart thermostat adjusts your home's temperature based on your habits, saving energy. The Internet of Things (IoT) gives everyday objects, such as lights, cars, and even coffee makers, the ability to "think" and act smarter. IoT doesn't only connect devices, it connects the world.
By 2025, the Internet of Things (IoT) will be an integral part of daily life. From homes to hospitals, factories to farms, it’s creating a connected world that’s more efficient and convenient.
How IoT Is Changing the Way We Live
IoT is making life more convenient, safer, and efficient. It’s woven into our daily routines. Here’s how it’s transforming our world in 2025:
Convenience at Home
Smart devices save time and effort. Imagine waking up to a coffee maker that starts brewing when your alarm rings. Or a fridge that tells you when you’re low on milk. These small changes make mornings smoother.
Better Healthcare
IoT helps people stay healthy. Wearable devices remind you to exercise or take medicine. For older adults, IoT sensors can detect falls and alert family members or healthcare professionals in a timely manner. This means faster help and more independence.
Sunway Medical Centre has integrated IoT technology to remotely monitor patients' clinical and vital signs. Continuous data collection enables healthcare professionals to predict and assess patients' health status in real-time, allowing for proactive and personalised medical care.
Smarter Cities
The Internet of Things (IoT) makes cities better places to live. Smart bins tell waste collectors when they're full, so streets stay clean. Sensors in parking lots show drivers empty spots, reducing traffic. These changes save time and make cities more livable and less stressful.
The SMART Tunnel in Kuala Lumpur is a prime example of how the Internet of Things (IoT) is utilised in real-world infrastructure. This innovative tunnel serves a dual purpose — it acts as both a stormwater diversion channel and a motorway. During heavy rainfall, IoT sensors detect rising water levels and trigger an automated system to divert floodwaters away from the city centre, preventing flash floods. When not in flood mode, the tunnel operates as a motorway, helping drivers bypass the usual Cheras-KL traffic congestion during peak hours. It’s a smart solution that keeps the city moving, rain or shine.
Saving Money and Energy
IoT helps cut costs. Smart thermostats turn off your electrical items when no one's home. Smart meters track electricity use, so you can avoid wasting energy.
Smart bulbs and switches are now widely available in most electronics shops. You can now turn off your lights and electronics through your phone when you're not at home. This simple IoT-integrated device helps you save energy and your wallet, too.
Work and Productivity
Businesses use IoT to boost efficiency. Delivery companies track vehicles in real-time, saving fuel. The industrial IoT market, worth $269 billion in 2023, continues to grow, streamlining operations.
IoT acts like a quiet helper, improving life in ways big and small.
Why IoT Is Important in Today's Society
IoT is more than fancy gadgets—it’s vital for society in 2025. Here's why it's a game-changer:
Efficiency: IoT technologies automate routine tasks across industries, helping businesses and governments save valuable time and resources. This automation is crucial as Malaysia faces increasing demands for efficiency in sectors such as manufacturing, agriculture, and public services.
The traffic congestion issue in Malaysia can be addressed by utilizing IoT sensory devices that provide real-time data to help local councils plan for improved city and road development. By integrating IoT solutions, Malaysian companies can optimise operations, reduce costs, and focus on innovation to stay competitive in today's fast-paced world.
Health and Safety: The Internet of Things (IoT) is playing a vital role in saving lives through smart medical devices and safety systems. From connected smoke detectors that send instant alerts to wearable health monitors that track patients' vital signs in real time, these technologies help doctors and emergency responders make faster, life-saving decisions when every second counts.
Sustainability: Smart sensors monitor soil moisture and weather conditions, ensuring crops get precisely what they need—no more, no less.
Connected systems also manage water and electricity usage efficiently, reducing waste and emissions.
Connectivity: IoT seamlessly connects people and devices, creating a world where information flows in real-time. This connectivity empowers faster, more intelligent decision-making — whether it's optimising traffic lights in Kuala Lumpur or tracking supply chains in Malaysian factories.
As Malaysia continues to embrace 5G and innovative city projects, IoT is paving the way for a more connected, efficient, and data-driven society.
Economic Growth: The Internet of Things (IoT) is a pivotal component of Malaysia's digital economy, driving substantial GDP growth and job creation. With continued support from government policies and foreign investments, Malaysia is poised to become a leading digital economy in the region.
How IoT Will Shape the Future
The future of IoT is full of promise. By 2030, over 40 billion devices are expected to be connected, with the market reaching a value of $2.72 trillion. Here's what's coming:
Smarter Homes and Cities
Homes will predict your needs, like turning on your Air Conditioner before you arrive. Cities will utilise IoT to manage resources more effectively, implement brighter traffic lights, reduce traffic congestion, and enhance bus monitoring systems, thereby reducing our dependence on personal vehicles.
Advanced Healthcare
IoT will personalise medicine. Devices may detect diseases early, enabling us to receive the proper medication at the right time. IoT-connected robots could perform remote surgeries, helping people in rural areas in Sabah and Sarawak.
Self-Driving Cars
IoT will power autonomous vehicles. By 2025, the self-driving car market is projected to hit $36 billion, with cars communicating to avoid accidents. Tesla has already begun development of its autonomous car system. Wuhan, China, has already begun testing autonomous taxis, with Baidu operating a large fleet of fully autonomous robotaxis.
Farming and Food
IoT will boost food production. Sensors will monitor crops in real-time, reducing waste. The automotive IoT market, including connected farm vehicles, is expected to reach $23.6 billion by 2025.
Challenges to Overcome
The future has hurdles:
Security: With 152,000 IoT devices connecting every minute, cybersecurity is critical.
Privacy: Strict laws are needed to protect user data.
Cost: IoT must be affordable for all, not just the wealthy.
Solving these issues will unlock IoT's full potential.
