Definition: IoT (Internet of Things) is a network of physical “things”—devices embedded with sensors, software, and connectivity to exchange data.
- Perception Layer: Sensors/devices capture data.
- Network Layer: Transports data (Wi-Fi, 5G).
- Processing Layer: Cloud/edge analytics.
- Application Layer: Delivers IoT services.
- Sensors: E.g., DHT11, soil moisture sensors.
- Actuators: Motors, relays.
- MCUs: ESP32, Arduino.
- Connectivity: Wi‑Fi, BLE, LoRaWAN.
- Protocols: MQTT, CoAP, HTTP, Zigbee.
- Use TLS/SSL encryption.
- Strong device authentication.
- Secure OTA firmware updates.
- Network segmentation and access control.
