Hello all, this is Neel from Edureka, and welcome to this interesting session on Internet of Things projects. Now in this session, we’ll be talking about the top seven projects which are outstanding themselves in the Internet of Things domain now before we talk about each of these projects let me start off with a simple introduction to what is the Internet of Things basically is a concept or a technology which aims to connect all the devices to the Internet and help them communicate with each other using the Internet as a medium.
These devices can be anything it could be a TV it could be a mobile phone it could be a watch even your caras such anything that can be connected to the Internet can be considered as a device for the Internet of Things the intention of using the Internet as a medium of communication is to help you achieve a wider and a greater reach with respect to these devices again the end aim of Internet of Things is to help you create a smart world that’s out there now let’s talk about each of these projects.
Let’s start with number seven which is a biometric system now a biometric system is something that we always encounter on our daily basis as well because we always either use a fingerprint sensor or we use an iris scanning so it depends from organization to organization but how does this actually work the system there let’s take in case of this example has a fingerprint scanner now the first time that I am presenting my fingerprint it scans the fingerprint and considers this as part of an enrollment process from this fingerprint template.
Would it does is that it extracts certain key features that makes different from others and stores them into a database from then forward every time that I placed my finger on top of this fingerprint scanner it creates a template and compares this with all the templates that are present in the database if it matches then correspondingly let’s say gives me an attendance or lets me access a tour if it does not then it raises an alert with respect to that same now this is just a foundation.
Now as I said this biometric system can be fingerprint it can be is canny or it can be a combination of both as well voice recognition system is one of the key products in the biometric domain next we have smart irrigation system now I am someone who personally likes gardening a lot now this is something that would really make my life easier because usually what I do is that on Sundays I spend our two hours just watering and looking after my plants through a smart irrigation system.
What it does is that it checks the moisture present in the environment or in the water lines that I have created now to help you understand how it works usually there is two main Internet of Things devices that I used here which is the Adreno board and the Raspberry Pi your raspberry Pi becomes the main processing unit and I place an Adreno board for each of my water channels these addressing modes themselves are connected to multiple sensors which are part of this water channel.
What these sensors do is that they check the moisture present in these lanes as such let’s say a specific link does not meet the minimum required moisture than what it would do is that it would send a signal to the Raspberry Pi again all these devices are connected on the same wireless router network and the raspberry Pi would identify the lack of moisture and pass a signal to the relay, in turn, would initiate the water pump and water would be parked now in order.
Ensure that water is not wasted we would create gate controls and only the gate where the moisture is less would the gate be open once my sensor detects that the moisture level has gone beyond my required limit it would again say another signal to the Raspberry Pi asking it to stop the pump as well sothis, in turn, helps you to save a lot of water and also makes your life quite easier as well so after this your only task in your garden would be either setting up new plans or creating.
New water channels as such the next project in our list is a security camera and door unlock system now this is something that’s quite interesting and I’ve personally tried to start and it’s really something that you should try out as well here what happens is that you place a camera on top foot door which in turn clicks the photo of a person who comes into the frame now this photo is again sent to an analytical system which in turn compares this with all the photos that it possesses in order to identify.
Highly Sensitive Information:
Whether to let the user open the door or not now an evolution to this is that if it does not find the photo of that person it can notify the concern that so-and-so person is trying to access this door would you like to authorize this person and add his information to the database or would you like to deny the access to this person as well usually this is used in areas where you have highly sensitive information stored in order to maintain strict control to the access to this information.
Well another usage of the security camera and/or unlock system can be even at our homes when we can identify who’s come at our home when we’re not there and either decide to give them access to our homes or not now the next thing is something that we all really desire to have which is a smart home system can be something that really makes our life quite easy starting from energy management where the light control system is the AC.
Smart Home System:
Appliances that we use the thermostat all this is managed in short trying to cut down the power consumption that’s taking place my door management system is also part of this security system is also part of this my water management system again becomes a part of this Asma again these are key things that really stands out in the smart home system but again what I would personally recommend is that the limitations of a smart home are where our imagination stops anything.
That you wish to automate or may wish to make your life easier can be part of a smartphone system as well now a smart home usually is going to be a base for our next project which is a smart city is an evolution of a smart home here it’s not just the sensors of a single home that is connected here its correlation or a network or a connection between various organizations various domains.
Well as various segments of that city as a whole as such here the life of every single dependent person in that city becomes easier.A whole as well and in turn will really help develop that city to greater extends as such now the key factor here for a smart city is government support as well and if governments are really willing to take this step then I hope we would see the smart city completely built on the Internet of Things may be the next five to ten years as well now the next project is something that really stands out on a personal level this is Zelda Ocarina controlled home automation system.
