The Internet of Things (IoT) is a network of interconnected physical devices that communicate and share data over the internet.
How IoT Works?
IoT devices collect data via sensors, send it to cloud servers, process it, and take actions based on the data.
Key Components of IoT:
- Sensors & Actuators – Collect real-time data (e.g., temperature, motion, humidity).
- Connectivity – Devices communicate via Wi-Fi, Bluetooth, Zigbee, or 5G.
- Cloud Storage & Processing – Cloud platforms analyze data from devices.
- User Interface (UI) – Web or mobile apps for users to monitor and control devices.
- AWS IoT Core – Connects and manages IoT devices on AWS.
- Google Cloud IoT – Securely connects IoT devices to Google Cloud.
- Microsoft Azure IoT – Provides IoT solutions for industrial applications.
🛠 Example:
Simple IoT System Using Raspberry Pi
- Connect a temperature sensor to Raspberry Pi.
- Write a Python script to read data from the sensor.
- Send the data to AWS IoT Core using MQTT protocol.
- View real-time temperature data on a cloud dashboard.
