SS 117 IT Era Finals Reviewer: Internet of Things (IOT)

Study Notes

IoT allows people to automate and control everything remotely, view real-time data seamlessly, and integrate sensors, software, and networking devices
Sensors are fitted everywhere across devices, collecting real-time data consistently
Types of IoT sensors include:
- Acceleration/Tilt
- Ambient Light/Machine vision/Optical
- Leaks/Levels
- Vibration
- Humidity/Moisture/Water
- Electric
- Position/Proximity
- Motion/Velocity/Displacement
- Magnetic
- Chemical/Gas
- Temperature
- RFID/NFC
- Acoustic/Sound
- Force
- Ultrasounds/Radio
- Flow

Smart Homes: thermostats, lighting systems, appliances, and security systems that can be controlled remotely or automatically
Wearables: fitness trackers, smartwatches, and other devices that monitor health and activity levels
Connected Cars: vehicles with features like self-parking, remote diagnostics, and real-time traffic updates
Industrial IoT: sensors in machines and equipment that monitor performance and predict maintenance needs
Smart Cities: traffic management systems, environmental monitoring, and connected infrastructure that improve efficiency and quality of life

Advantages:
- Ability to access information from anywhere at any time on any device
- Improved communication between connected devices
- Automating tasks, improving quality of service, and reducing human intervention
Disadvantages:
- Increased risk of confidential information theft
- Difficulty in managing and collecting data from numerous devices
- Lack of international standard for IoT device compatibility
- Risk of system corruption and bug propagation

IoT powered by 5G technology for ultra-fast data transfer and real-time processing
Greater adoption of wearables for fitness tracking, health monitoring, and personalized recommendations
Increased focus on security and privacy concerns
Integration of blockchain and AI for enhanced security, transparency, and problem-solving
