What is IoT?

IoT (Internet of Things) means everyday devices that can connect to the internet and communicate with each other.

They collect data, send it online, and sometimes make smart decisions automatically.

Example 1: Apple Watch + iPhone

• Collecting Data:

  The Apple Watch tracks your steps, heartbeat, sleep, and other health data.

• Internet & Sharing:

  The watch sends this information to your iPhone through Bluetooth/Wi-Fi, and your iPhone can upload it to iCloud (online storage).

• Why it’s useful:

  • You can see your health progress anytime.
  • Your doctor can check your reports remotely.
  • The watch can alert you if your heartbeat is abnormal.

This shows how IoT helps in personal health monitoring.

Example 2: CCTV Camera + iPhone

• Collecting Data:

  The CCTV records video of your home or office.

• Internet & Sharing:

  The CCTV sends the live video through the internet to your iPhone app.

• Why it’s useful:

  • You can check your home security even if you’re far away.
  • If motion is detected, the camera can send an alert to your iPhone.
  • Videos can be stored in the cloud for later review.

This shows how IoT helps in home security.

Key Idea

IoT = Device (collect data) → Internet (share data) → iPhone (control & monitor).

It makes life smarter, safer, and more connected.
