Internet of Things (IoT)

Why people are talking so much about IoT? Is IoT really future? | by Thinkwik | Medium 

What is Internet of Things (IoT)??

     Connecting everyday things embedded with electronics, sensors, software, and

other technologies for the purpose of collecting and exchanging data with other 

devices and systems over the internet without human interaction is called as 

Internet of Things (IoT).

IoT Features

Some of the common features of IoT are connectivity, analyzing, integrating, active

engagement, and many more.

Connectivity: Establishing proper connection between all the things of IoT to  

IoT platform like server or cloud.

Analyzing: After the connection, the real time analyzing of data is done. it is to 

build effective business intelligence.

Integrating: IoT integrating various models to improve user experience.

Artificial Intelligence: It makes the machine think like the human. for E.g.Social 

media applications are using the support of AI to monitor content, suggest 

connections, and serve advertisements to targeted users.

Active Engagement: The connected devices or services have the active 

engagement between each other.

Endpoint Management: The Endpoint Management of all the IoT system is very 

important. For e.g. In the above example of social media finally it depends on the 

user whether the suggested connections should be confirmed or not.

Why is Internet of Things (IoT) so important?

IoT has become one of the most important technology nowadays. We can connect

everyday objects like cars, mobiles, home appliances to the internet via embedded

devices.Using IoT, devices can share and collect data with minimal human 

intervention.

Advantages and Disadvantages Of IoT :

Advantages Of IoT :

It minimizes human efforts.

It saves time.

Data collection is enhanced due to IoT.

Disadvantages Of IoT :

System security is a big concern while dealing with IoT. 

The IoT system provides substantial personal data even without the active 

participation of the user, hence privacy of the user is also a concern.

It is quite complicated to design, develop and maintain the IoT system.

Optocoupler

Image
  Optocoupler :              An optocoupler is a device that uses a short optical transmission path to transfer a signal   between elements of a circuit, typically transmitter and receiver which are electrically isolated.              It is basically used as isolator circuit. Fig. Circuit Symbol of optocoupler Construction              Basically optocoupler is a pair of LED and phototransistor enclosed in a single package.                           Here LED and phototransistor are isolated so that light may travel across a barrier but electrical current may not. Working Principle Specifications and Parameters :              Device operatin...

Zener Diode, IC 78XX and 79XX as a Voltage Regulator

Image
 Zener Diode as a Voltage Regulator Fig. Voltage regulator circuit using Zener diode The Zener diode is always connected in reverse biased in series in a voltage regulator circuit as shown in above fig. The Zener diode is selected with a Vz equal to the voltage desired across the load. The Zener diode acts as a ‘bypass valve’ through which more current flows when an increase in input voltage or a decrease in load current occurs, maintaining the voltage at the output nearly constant at Vz. The resistance Rs drops the excess voltage from the input to give the desired output; hence this circuit cannot compensate for input voltages smaller than desired output. The selection of R is made by using the following equation Rs= (Vin-Vout) / Iin Where, I = Iz + I L When R L is not connected,  I L =0 i.e. I= Iz = Iz(max) Therefore, Zener must be capable of passing all the current I through it. For Zener to be remaining in breakdown, Iz must not be permitted to fall below Iz(min) to work...

Zener Diode

Image
  ·          Zener diode: Construction:   It is a heavily doped pn junction diode which is always used in reverse bias mode.              The depletion layer is very narrow.              Zener diode can operate in any of the three regions:              i)forward, ii) leakage, iii) breakdown Symbol of Zener Diode: In Zener diode, the barrier separating the two bands is very narrow, hence tunnelling of electrons from p-side valence band to the n-side conduction band occurs. This constitutes a reverse current from n-region to p-region which is called as Zener effect. At a particular voltage, a very sharp reverse current increases sharply and this voltage is known as Zener breakdown voltage. Because of this property, Zener diode is used as voltage regulators...
