IoT (Internet of Things) is a technology where different devices and objects are connected through the internet and automatically exchange information. It works using sensors, networks, data processing, and cloud systems, making our daily lives smarter and more automated.
Sensors & Devices
- Sensors collect data (temperature, humidity, motion, light).
- Devices have microcontrollers or embedded systems to process this data.
Connectivity (Network)
- Devices connect via Wi-Fi, Bluetooth, Zigbee, or mobile networks.
- Data is sent to cloud servers.
Data Processing (Cloud/Server)
- Cloud platforms analyze the data.
- AI or Machine Learning can make decisions based on the data.
User Interface (App/Dashboard)
- Users control devices through mobile apps or web dashboards.
- Example: Turning lights on/off or checking fridge temperature remotely.
Real-Life Applications
- Smart Home: Control lights, fans, AC via mobile apps.
- Smart City: Traffic management, smart street lights.
- Smart Industry: Automated production, machine monitoring.
- Healthcare: Smartwatches or fitness bands for health tracking.
- Agriculture: Sensors monitor soil moisture and weather to control irrigation.
