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.

2. Working Principle of Internet of Things

Consider reservation counters and banks for example: Typical computer system work on the principle, Input-->process-->output. In conventional system input is keyed in by human beings. The software algorithm running at the computing system, process the input data and produces an output. If people responsible are lethargic or lazy, often the speed and accuracy of the system is lost. But in IoT we do not have this issue. Inputs are replaced by relevant sensors. Hence possibility of human error can be eliminated to the great extent. Processing happens in cloud and returned to receiver end. Block diagram of the process-flow: In many IoT systems, sensors forward data via short-range wireless communication protocols such as Bluetooth, zigbee, wifi to the local computing system. Data gets pro-processed and sent to the central server or the cloud system. Analytics software system takes informed decisions at the cloud platform and will reach the receiver end device.  In few cases this ...

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...

6.5 Capacitor and Capacitance

  Description:  Capacitance is the capacity or ability of a capacitor to store electrical energy. Capacitor is a component to store and discharge energy. The other name for capacitor is condenser. Image shows different variants of Capacitor Working: The capacitor is made up of two close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. Once the battery is connected, negative charges on the right side gets attracted towards the positive terminal of the battery and on the left side, negative charges gets repelled away from the negative terminal of the battery. As the negative charges leaves the piece of metal in the right, it makes that piece of metal positively charged, and the piece on left becomes negatively charged. Both sides has same magnitude of charge. As the plate on the right becomes positively charged, the next electron gets confused where to move, whether to the positive term...
