- 3. History of IOT •1999- The term "Internet of Things" was used by Kevin Ashton during his work at P&G which became widely accepted •2004 - The term was mentioned in famous publications like the Guardian, Boston Globe, and Scientific American •2005-UN's International Telecommunications Union (ITU) published its first report on this topic. •2008- The Internet of Things was born •2011- Gartner, the market research company, include "The Internet of Things" technology in their research
- 4. Iot Definition • “The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.”
- 5. How IoT works? • 1) Sensors/Devices • 2) Connectivity • 3) Data Processing • 4)User Interface
- 6. 1) Sensors/Devices • Sensors or devices are a key component that helps you to collect live data from the surrounding environment. • All this data may have various levels of complexities. • It could be a simple temperature monitoring sensor, or it may be in the form of the video feed.
- 7. 2) Connectivity • All the collected data is sent to a cloud infrastructure. • The sensors should be connected to the cloud using various mediums of communications. • These communication mediums include mobile or satellite networks, Bluetooth, WI-FI, WAN, etc.
- 8. 3) Data Processing • Once that data is collected, and it gets to the cloud, the software performs processing on the gathered data. • This process can be just checking the temperature, reading on devices like AC or heaters. • However, it can sometimes also be very complex like identifying objects, using computer vision on video.
- 9. 4)User Interface • The information needs to be available to the end-user in some way which can be achieved by triggering alarms on their phones or sending them notification through email or text message. o The user sometimes might need an interface which actively checks their IoT system. • For example, the user has a camera installed in his home. He wants to access video recording and all the feeds with the help of a web server.
- 10. What is an example of an Internet of Things device? • A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. • An IoT device could be as fluffy as a child's toy or as serious as a driverless truck. • Some larger objects may themselves be filled with many smaller IoT components, such as a jet engine that's now filled with thousands of sensors collecting and transmitting data back to make sure it is operating efficiently.
- 11. IoT benefits to organizations • monitor their overall business processes; • improve the customer experience (CX); • save time and money; • enhance employee productivity; • integrate and adapt business models; • make better business decisions; and • generate more revenue.
- 12. Why Is Internet of Things (IoT) so important? • Over the past few years, IoT has become one of the most important technologies of the 21st century. • Now that we can connect everyday objects—kitchen appliances, cars, thermostats, baby monitors—to the internet via embedded devices, seamless communication is possible between people, processes, and things. • By means of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention.
- 13. IoT Applications • Smart Thermostats • Connected Cars • Activity Trackers • Parking Sensors • Connect Health • Smart City
- 14. Challenges of Internet of Things (IoT) • Insufficient testing and updating • Concern regarding data security and privacy • Software complexity • Data volumes and interpretation • Integration with AI and automation • Devices require a constant power supply which is difficult • Interaction and short-range communication
- 15. Advantages of IoT • Ability to access information from anywhere at any time on any device; • Improved communication between connected electronic devices; • Transferring data packets over a connected network saving time and money; and • Automating tasks helping to improve the quality of a business's services and reducing the need for human intervention.
- 16. Disadvantages IoT • As the number of connected devices increases and more information is shared between devices, the potential that a hacker could steal confidential information also increases. • Enterprises may eventually have to deal with massive numbers -- maybe even millions -- of IoT devices, and collecting and managing the data from all those devices will be challenging. • If there's a bug in the system, it's likely that every connected device will become corrupted. • Since there's no international standard of compatibility for IoT, it's difficult for devices from different manufacturers to communicate with each other.
