Study Notes

Internet of Things (IoT) Data Analytics

IoT data analytics involves collecting, analyzing, and interpreting data from IoT devices.
These devices continuously gather data and transmit it over the internet.
The goal is to transform unstructured data into meaningful insights for decision-making and improving various processes.

Data Collection

IoT devices collect data from their environment, such as temperature, humidity, motion, light levels, etc.
The data collection process involves:
- Sensors: Devices that detect and measure physical properties.
- Data Transmission: Using communication protocols like Wi-Fi, Bluetooth, and cellular networks to send data to a central system.
Examples of data collection devices include:
- Thermocouple Temperature Sensor: Measures temperature and converts it into an electrical signal.
- PIR (Passive Infrared) Sensor Motion Detector: Detects movements and triggers actions like turning on lights or sounding alarms.
- Smart Appliances: Wi-Fi enabled devices controlled remotely via smartphones or voice commands (e.g., Smart Refrigerators, Smart Ovens, Smart Speakers, Smart Lights).

Data Processing

Collected data must be processed to extract meaningful insights.
Edge Processing: Some data processing is done locally on the device or nearby edge servers to reduce latency and bandwidth usage, filtering, aggregation, and preliminary analysis.
Cloud Processing: More complex processing tasks are often handled in the cloud, where powerful servers can perform advanced analytics, machine learning, and data integration.

Data Storage

Processed data is stored for future analysis and decision-making.
Local Storage: Data is stored locally on the device or edge servers for quick access and low latency requirements.
Cloud Storage: For scalability and long-term storage, data is stored in cloud databases and data lakes, providing flexibility for handling large volumes of data and supporting various data management and retrieval operations.

Role of Big Data in IoT

Big data refers to the massive amount of data generated by IoT devices, such as sensors and cameras.
Key components of Big Data in IoT:
- Data Collection: IoT devices collect data from their surroundings.
- Data Storage: Data is stored in large databases, often in the cloud.
- Data Analysis: Stored data is analyzed to find patterns and insights.
- Real-time Processing: Some data is processed immediately for quick decision-making.

Machine Learning (ML) in IoT

ML helps IoT systems learn from collected data and make intelligent decisions.
Key applications of ML in IoT:
- Predictive Maintenance: ML predicts when a machine might break down, allowing for maintenance before failure.
- Anomaly Detection: ML identifies unusual patterns in data, indicating potential problems like security threats.
- Automation: ML automates tasks based on collected data, reducing the need for human intervention.
