What Are IoT Embedded Projects?

An Embedded System is a combination of hardware (microcontrollers, sensors, actuators) and software (firmware) designed to perform specific tasks.
The Internet of Things (IoT) connects these devices to the internet so they can send, receive, and process data remotely.

When combined, IoT Embedded Projects use embedded hardware to collect real-world data and IoT platforms to transmit and analyze that data via cloud or mobile apps.

Basic IoT Architecture

Sensors/Devices → collect data (temperature, motion, light, etc.)
Microcontroller (ESP32, Arduino, Raspberry Pi) → processes and sends data
Network Layer → Wi-Fi, Bluetooth, Zigbee, or LoRa communication
Cloud/Server → stores and analyzes data
User Interface → mobile app or web dashboard to control devices

Example:

Smart Agriculture System: Soil moisture sensor → ESP32 → Wi-Fi → ThingSpeak → farmer’s mobile dashboard.
