Overview
This lecture introduces the Internet of Things (IoT) and highlights seven common examples of its use in daily life, emphasizing the importance of cloud technology, networking, and security in IoT careers.
Origins and Growth of IoT
- IoT connects everyday objects to the Internet, allowing data collection and remote control.
- The term "Internet of Things" was coined in 1999, though early examples appeared earlier (e.g., networked Coke machine in the 1980s).
- IoT became widespread due to cheap microprocessors, embedded operating systems, and universal Internet access.
- By 2030, over 29 billion IoT devices are expected globally.
Everyday Applications of IoT
1. Smart Home Security
- IoT integrates alarms, sensors, and cameras for real-time home monitoring and remote control via mobile apps.
- Features include personalized access codes, geofencing, and advanced authentication like facial recognition.
2. Smart Home: Heating & Cooling
- Smart thermostats and sensors adjust temperature and humidity automatically, controlled remotely by apps or voice assistants.
- Systems monitor air quality, alerting users to gas leaks, fire, or water issues.
3. Smart Home: Kitchen
- Appliances like fridges, ovens, and toasters are Wi-Fi enabled for remote monitoring and voice assistant integration.
- Features include interior cameras, recipe touchscreens, and shopping list management.
4. Smart Driving
- IoT in vehicles enables services like remote diagnostics, emergency response, and real-time navigation apps (e.g., Waze).
- GPS and sensors improve safety and traffic management.
5. Smart Toll Collection
- Electronic toll collection uses vehicle transponders, sensors, and cameras for automated toll payment and vehicle classification.
- Plates are photographed for billing if transponders are absent.
6. Wearables
- IoT-enabled wearables track fitness, health metrics, and location via sensors and GPS, with data uploaded to the cloud.
- Devices monitor steps, activity, and can display specialized data for activities like golf.
7. Healthcare
- IoT medical devices monitor vital signs, track medication, and enable remote diagnostics (e.g., smart pillboxes, pacemakers).
- The "Internet of Medical Things" (IoMT) includes both wearable and implantable devices.
Key Terms & Definitions
- IoT (Internet of Things) — Network of interconnected devices that collect and exchange data.
- Cloud — Remote servers that store, process, and manage data.
- Geofencing — Technology that triggers actions when a device leaves or enters a set area.
- Transponder — Device that emits a signal for identification and data exchange.
- IoMT (Internet of Medical Things) — IoT applied specifically to healthcare devices.
Action Items / Next Steps
- Explore cloud technology training, focusing on AWS, Azure, or Google Cloud, especially for networking and security fundamentals.
- Review certification paths such as AWS Certified Cloud Practitioner or Azure Administrator.
