Real-World Applications of IoT



Real-World Applications of IoT

๐ŸŒ What is IoT (Internet of Things)?

The Internet of Things (IoT) refers to a system of interconnected physical objects — “things” — that are embedded with sensors, software, and connectivity to collect and exchange data over the internet.

These "things" can range from household appliances and wearables to industrial machines, farm equipment, vehicles, and even buildings.

⚙️ How IoT Works (Step-by-Step)

Sensing

Devices (e.g., temperature sensors, cameras, GPS chips) gather real-time data

Examples: Smartwatch measures heart rate, sensor detects soil moisture

Connectivity

Data is transmitted using Wi-Fi, Bluetooth, 4G/5G, LPWAN, or Zigbee

Devices communicate with cloud servers or local edge systems

Data Processing

Software (often AI/ML) analyzes the incoming data

Example: Detects abnormal heart rhythm, machine overheating, or gas leakage

Action or Alert

Sends notifications, triggers automated responses, or logs insights

Example: Air conditioner turns on automatically, or alarm sounds in fire
