  8. 8. sensors Sensors are now found in a wide variety of applications, such as smart mobile devices, automotive systems, industrial control, healthcare, oil exploration and climate monitoring. Sensors are used almost everywhere, and now sensor technology is beginning to closely mimic the ultimate sensing machine … the human being. data.ex- Electronics,robots,automobiles etc . 11/6/2016 8internet of things
  9. 9. connectivity Connectivity, it is one of the main things to keep in mind while developing any Internet-of-Things (IoT) project.ex- Communication(wifi,bluetooth,RFID,NFC) 11/6/2016 9internet of things
  10. 10. RFID(Radio-Frequency Identification) is a communication method used for tracking and identifying objects wirelessly.) Passive RFID tags primarily operate at three frequency ranges: •Low Frequency (LF) 125 to 134 kHz • High Frequency (HF) 13.56 MHz • Ultra High Frequency (UHF) 856 MHz to 960 MHz 11/6/2016 10internet of things
  11. 11. RFID Tags The tags are the end points in an RFID system. They store identity information along with other information as required by the purpose of the tag. There are two types of tags: Active Tags: These tags have an on-board power source of some sort, usually a battery, which means they can transmit stronger signals and therefore have more range. This type of tag can periodically transmit a signal irrespective of a reader. Passive Tags: These tags do not have any internal power source and get activated in the vicinity of a reader. Your metro or bus pass is generally a passive tag, which gets activated when you touch it to the reader. These tags harvest the radio energy transmitted by the reader. 11/6/2016 11internet of things
  12. 12. TAG • Passive tag – note the small size of the tag in comparison. • Active tag Inside of an active RFID tag – note the on-board battery. 11/6/2016 12internet of things
  13. 13. Reader Readers have a similar construction to an RFID tag. They have an antenna to receive and transmit signals to/from the tags For example, the reader in subway stations is at the entry point. When the rider places a card (tag) on the reader, it reads the available money in the card and grants the user entry. At the passenger’s exit, it calculates the fare and updates the amount on the card. 11/6/2016 13internet of things
  14. 14. 11/6/2016 14internet of things  RFID tags can have three main components:  An Integrated Circuit (IC) for storing identity information, processing it and modulating/demodulating the RF signals.  An antenna to receive and send the radio signals.  A power source (battery) if an active tag.
  15. 15. NFC(Near-Field Communication) Near-Field Communication (NFC) is an RF-based communication protocol NFC smartphones pass along information from one smartphone to the other by tapping the two devices together, which turns sharing data such as contact info or photographs into a simple task. Applications like Android Beam facilitate . NFC is designed for very short-range communication (a few centimeters). It is one of the most power-efficient communication protocols. NFC also operates in the 13.56 MHz band. 11/6/2016 15internet of things
  16. 16. NFC is being used to open car doors in NFC-enabled car keys with car manufacturers such as BMW.  NFC has two types of devices (one thing to note is that, in NFC, the device can act as a tag or a reader):  Initiator: The device that initiates the communication is labeled as the initiator. It actively generates an RF field that can power the passive target.  Target: This is the device that receives the information from the initiator. The target can either be passive (in the case of simple NFC tags) or active for peer to peer communication, such as in smartphones. 11/6/2016 16internet of things

  18. 18. Application of iot • smart homes • Wearable • Retail • Smart cities • transportation • Heathcare • Energy managment 11/6/2016 18internet of things
  19. 19. CONNECTED/SMART HOMES Definition of connected home is different for different people. In simple words a smart home is the one in which the devices have the capability to communicate with each other as well as to their intangible environment. A smart home gives owner the capability to customize and control home environment for increased security and efficient energy management. There are hundreds of IoT technologies available for monitoring and building smart homes. Nest Learning Thermostat is a revolutionary concept which gives you many benefits. Its breakthrough technology and internet of things based concepts make it highly efficient electric appliance. Usually thermostats incur almost half of the energy bills. However with Nest you can save up to 15% on cooling bills as well as 12% on heating bills on average. 11/6/2016 19internet of things
