IoT (Internet of Things)
Internet of Things
A system that connects all kinds of physical objects to the internet, enabling remote control and data collection
In Simple Terms
IoT is a system where all kinds of everyday objects connect directly to the internet. Sensors attached to those objects can monitor their status, and you can control them remotely from a smartphone or other device. Common examples include remotely controlling your air conditioner or heating a bath, checking a bus's real-time location, and automated irrigation systems in fields. Factories also use IoT to monitor equipment through data and predict when failures are likely to occur.
Behind the Name
Short for Internet of Things. "Things" refers to everyday objects that were traditionally not connected to the internet — home appliances, cars, factory machinery, and more. IoT is about giving these objects network connectivity so they can send and receive data online.
Take a Closer Look!
IoT is a system where all kinds of physical objects that were previously unconnected to the internet join a network and share information via the internet.
The core of this technology is sensors and communication.
Sensors attached to objects continuously collect data — temperature, vibration, location, video — and send it to the cloud and other systems via the internet.
You can also go the other way: send commands from the internet back to the objects, like "turn on" or "change the temperature setting."
A familiar example is the smart home.
IoT is what lets you switch on your air conditioner or heat up a bath remotely from your smartphone, even when you're out.
Other examples include transit systems that show a bus's real-time location on your phone, and agricultural systems that monitor soil moisture and trigger automatic irrigation — the range of applications is surprisingly wide.
And it's not just about convenience — IoT matters a lot for business and society too.
In factories, for instance, by continuously monitoring vibration data from machinery, AI can predict when a breakdown is coming, and parts are replaced before anything actually fails.
Being able to tap into the enormous amounts of data that physical objects generate — cutting waste and creating new value in the process — is what makes IoT so powerful.
