3. IOT-Introduction
• The Internet of Things (IOT) is the network of physical objects—devices,
vehicles, buildings and other items embedded with electronics,
software, sensors, and network connectivity—that enables these objects
to collect and exchange data.
• IOT allows objects to be sensed and controlled remotely across existing
network infrastructure, creating opportunities for more direct
integration between the physical world and computer-based systems,
and resulting in improved efficiency, accuracy and economic benefit.

7. Application of IoT- Smart Home

8. Application of IoT- Smart Grid
 Smart grid uses information about the behaviours of electricity suppliers and
consumers in an automated fashion
 This technology helps in:
 Deliver Power more efficiently
 Improve operations
 Reduce emissions and management costs
 Restore power failure faster

9. Application of IoT- Smart Shopping Mall
 Geo-targeted SMS campaigns
 Simply put, geo-targeted SMS campaigns deliver content directly to a consumer's mobile
device by using their specific geographic location. Brands use this information to create and
drive their sales campaigns.
 Smart shelves
 It is a store shelf that is equipped with an RFID (radio frequency identification) reader. The
RFID reader scans all of the tagged items on the shelf and notifies the backend system about
the existing items.
 Self-checkout kiosks
 This is where IoT applications such as self-checkout kiosks are changing the game in retail.
 This is where IoT applications such as self-checkout kiosks are changing the game in retail.
Self-checkout kiosks allow customers to digitally pay for their purchases without human
intervention. This technology has advanced significantly over the years.

ARDUINO NODE MCU RASPBERRY PI

12. Hardware- Sensors
 A sensor is a device whose purpose to sense (i.e. to detect) changes in
physical environment. It detect events or changes in quantities and provides
a corresponding output, generally as an electrical or optical signal.
 Example:
A temperature sensor converts temperature to an output voltage.
A temperature sensor converts temperature to an output voltage.

13. Sensor Types
 On basis of power: (i) Active sensors (ii) Passive Sensors
 Based on conversion Phenomenon: Photoelectric, Thermoelectric,
Electrochemical, Electromagnetic etc.
 Based on Output: Analog Sensors, Digital Sensors

15. Software – Arduino IDE
• Arduino IDE can be downloaded from: https://www.arduino.cc/en/software
• Software to compile the C code for the microcontroller
• Easily interpretable inbuilt functions

16. Arduino IDE Initialization steps
 Package/Library Installation for sensor modules
 Selection of Board from Board Manager
 Assigning the Port to the Board
Software – Arduino IDE
 Assigning the Port to the Board
 Interfacing sensors with Arduino Board
