Microcontrollers are compact, low-power computing devices specifically designed for embedded systems
Consist of a processor, memory, and input/output peripherals integrated onto a single chip (system-on-chip)
is the low-level software programmed onto the microcontroller to control its operation and interact with hardware components
Firmware development involves writing code in languages such as C, C++, or assembly to implement the desired functionality of the embedded system
Debugging and testing firmware is crucial to ensure reliable operation and identify any issues or bugs
Real-Time Operating Systems and Low-Power Design
Real-time operating systems () are specialized operating systems designed for embedded systems that require deterministic and timely execution of tasks
RTOS provides a framework for managing tasks, scheduling, and resource allocation to meet real-time constraints
techniques are employed in embedded systems to minimize energy consumption and extend battery life
Involves optimizing hardware components, implementing power management strategies (sleep modes), and efficient software design
Low-power design is critical for battery-operated devices (wearables) and systems deployed in resource-constrained environments (remote sensors)
IoT Communication and Protocols
IoT Protocols and Cloud Connectivity
IoT protocols are standardized communication protocols designed for efficient data exchange between IoT devices and servers
Common IoT protocols include (Message Queuing Telemetry Transport), (Constrained Application Protocol), and (Hypertext Transfer Protocol)
MQTT is a lightweight publish-subscribe protocol that enables efficient communication between devices and servers over low-bandwidth networks
Cloud connectivity allows IoT devices to send data to and receive commands from cloud-based platforms for storage, processing, and analysis
IoT platforms (, ) provide cloud services and APIs for managing and interacting with IoT devices
Edge Computing and Security in IoT
involves processing and analyzing data closer to the source (IoT devices) instead of relying solely on cloud-based processing
Enables real-time decision making, reduces latency, and minimizes data transmission over networks
Edge devices (gateways, smart sensors) have enhanced processing capabilities to perform local data processing and filtering before sending relevant information to the cloud
Security and privacy are critical concerns in IoT systems due to the large amount of sensitive data collected and transmitted
IoT security measures include , , access control, and secure communication protocols to protect data confidentiality and integrity
Privacy-preserving techniques () are employed to safeguard user privacy and comply with regulations (GDPR)
IoT Applications and Data
Sensor Integration and Data Analytics
IoT applications heavily rely on to collect data from the physical world
Sensors measure various parameters (temperature, humidity, motion) and convert them into digital signals for processing
Sensor data is transmitted to IoT devices or gateways for further analysis and decision making
Data analytics techniques are applied to extract insights and patterns from the collected sensor data
algorithms can be used to detect anomalies, predict trends, and optimize system performance based on the analyzed data
Wearable Technology and Smart Home Systems
Wearable technology refers to IoT devices designed to be worn on the body, such as smartwatches, fitness trackers, and smart clothing
Wearables collect data related to user activity, health metrics (heart rate), and environmental conditions
Enable personalized monitoring, fitness tracking, and health management applications
Smart home systems integrate IoT devices to automate and control various aspects of a home environment
Smart home devices include smart thermostats, smart locks, smart lighting, and voice-controlled assistants (Amazon Alexa, Google Home)
Enable remote monitoring, energy management, and convenience through automated control and intelligent decision making based on user preferences and sensor data
