5.2 Applications of IoT (Wearable)

Introduction:

There are wide range of wearable devices in IoT such as fitness band, smart watches, smart glasses, smart ring, smart clothing, smart shoes and smart jewelry. These devices help humans to upgrade their daily lifestyle.  Let’s look at a few.


FITNESS BAND:

  • Fitness band / smart bracelet / smart band measures various things that are the result of physical exertion such as number of steps taken, the heartbeat, the calorie burnt, the distance travelled and the quality of sleep. 
  • Optical heart rate sensor in the bands, measures beat-to-beat variations from your recorded heart rate to determine a comfortable breathing rate.  
  • Bands are capable of tracking the calories burnt and can record how well you slept. 
  • It can be synced with phones to show the information and are different from smart watches and mobile watches. There are bands with both with and without display screen.


SMART GLASSES:

  • Smart glasses are augmented reality glasses embedded with sensors, camera, microphone, processor, rechargeable battery and many more. It helps us access internet, reply to messages, answer calls, listen to music, speak to a voice assistant and view notifications on spot. 
  • Smart glasses have built-in cameras and can record videos at a touch of a button.
  • There is also tint control. So, you can change the darkness of your glasses as desired. 
  • These have small speakers aimed at the ear, so you can listen to music or podcast even without having the earbuds in. 
  • The option to use the google search engine through the glasses using WIFI or smartphone’s data connection.
  • The ability to have translations streamed straight to the wearer through the screen. 
  • The tiny led display in the lens helps us project these in-front of the eyes. The processor with memory enables these features to work smoothly. 
  • These smart glasses look pretty much similar to normal glasses but slightly thicker on the sides.

3. History of IoT

Brief History: The term ‘Internet of Things’ was coined in 1999 by the computer scientist Kevin Ashton in the presentation he made while working at Procter & Gamble.  Ashton proposed putting radio-frequency identification (RFID) chips on products to track them through a supply chain is essential to communicate between people and things and things themselves. Wanting to bring Radio Frequency to the attention of P&G‘s senior management, Ashton called this presentation as ‘Internet of Things’ to incorporate the cool new trend of 1999 the internet. Though Ashton mentioned it in 1999, the  first appliance was a coke machine invented in the early 1980s at the Carnegie Melon University. A group of students from the university created a way to get their campus Coca-Cola vending machine to report on its contents through a network in order to save them the trek if the machine was out of Coke. They installed micro-switches into the machine to report on how many Coke cans were a...

6.2 What is Voltage?

Description: The electrons in a conductor (copper for example) freely move from atom to atom, but in a completely random way.  Motion of free electrons is normally haphazard.  So, a sort of pressure or push helps electrons to move in a particular direction.  The technical term for this pressure or push is electromotive force, EMF for short or sometimes simply E. It creates pressure on the electrons which channelizes them to flow in a single direction. But you know it more commonly as voltage. Voltage: Voltage (V) is the unit of potential difference. More clearly, voltage is the difference in potential, between two points.  Basically, to find the difference, we need two points. Similarly, to measure volt we need two points. Let A and B are the two points connected through any conducting material. Potential of A is 50 and B is 30 and the unit of potential is coulomb (Q). ‘Point A’ has high potential which means more electrons. ‘Point B’ has low potential which means l...

7. What is Arduino Nano

The Arduino Nano is a microcontroller.  The Arduino Nano is Arduino’s classic breadboard friendly designed board with smallest dimensions. The Arduino Nano comes with pin headers that allow for an easy attachment onto a breadboard and features a mini-B USB connector. It is an intelligent development board designed for building faster prototypes with the smallest dimension. Oldest member of Nano family. Enough interface for breadboard friendly applications Heart – Atmega328 microcontroller Clocked at a frequency of 16MHZ Same functionalities as the Arduino Duemilanove. 22 digital pins. 8 analog pins. A mini USB port. First embedded micro-controller in the Nano series   Features: High performance low power 8-bit processor. Achieve up to 16 MIPS for MHZ clock frequency. Flash memory – 32 KB of which 2 KB used by bootloader. Internal SRAM – 2 KB EEPROM – 1 KB PWM Channels – 6 Power: Mini – B USB Connection 6-20 Unregulated external po...
