4. It is the intelligent connectivity of physical devices driving massive gains in
efficiency, business growth, and quality of life.
5. Idea of Internet of Things
If we had computers that knew everything there was to know about
things—using data they gathered without any help from us—we
would be able to track and count everything, and greatly reduce
waste, loss and cost.
cofounder of Auto-ID Center-
Kevin Ashton supposedly coined the phrase "Internet of Things" in 1999.
It is estimated that more than 30 billion devices will be wirelessly connected to
the internet of things by 2020.
6. Building blocks of IoT
Four things form basic building blocks of IoT system
2. Microcontroller / Microprocessor
3. Connectivity / Gateway
4. End user Application
7. Sensors ,actuators etc….
• A device which detects or
measures a physical property and
records, indicates, or otherwise
responds to it.
• Heart of the IoT devices.
8. Microcontroller (SoC) and
Used in automatically controlled products and
Economical to digitally control even more devices
Incorporates the functions of a computer's central
Powerful graphics processing power
• Arduino is an open-source project that created
microcontroller-based kits for building digital
devices and interactive objects that can sense
and control physical devices.
• An Arduino board consists of an Atmel 8-, 16- or
32-bit AVR microcontroller
10. Raspberry pi
• The Raspberry Pi is a series of single-board
• Credit card-sized.
• It has video controller (Advantage over
11. Connectivity / Gateway service
Connectivity in the sense used to connect the device to end user
12. End user Application
End user Hardware or Software application to control/adjust the IoT device.
May be Android ,iOS apps etc
May be hardware like remote control.
Nest thermostat app
Philips Hue app
13. Working of an IoT device
14. Applications of IoT
Medical and healthcare
Building and home automation
15. Medication dispensing service
Created for elderly people.
Alerts the patient for medication using a light and
Prefilled cups with medication are dispensed.
use 80 percent less power
16. Amazon Echo
Electronic, programmable, and self-learning Wi-Fi-enabled
Optimizes heating and cooling of homes and businesses to
Amazon Echo is a voice command device from Amazon.com
functions include question answering, playing music and controlling
Compatibility:-No international standard of compatibility of tagging and
monitoring the equipments.
Complexity:-With more complex systems there are more opportunities of
Privacy/Security:-With the transmission of the IoT data the risk of data theft
and other such cyber threats increases.
