Internet of things and smart home

1.What is the LOT?

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction .(By Wikipedia)


2.Whar are the applications of LOT?

The extensive set of applications for IoT devices is often divided into consumer, commercial, industrial, and infrastructure spaces.


3.Consumer applications of LOT:Smart home

A growing portion of IoT devices are created for consumer use, including connected vehicles, home automation, wearable technology as part of Internet of Wearable Things (IoWT), connected health, and appliances with remote monitoring capabilities.

3.1Smart Home Example

At 7:00 AM,you awake to the sound of your favourite CD playing in the background;the lights your bedroom switch on;’fading up’ to allow you to wake up in your own time.The downstairs intruder alarm system is de-activated.In the kitchen the coffee machine turns on to make a drink.The ground floor curtains and blinds open;the towel heater in the bathroom warms the towels.And you haven’t even got up yet.



IoT devices are a part of the larger concept of home automation, which can include lighting, heating and air conditioning, media and security systems.Long-term benefits could include energy savings by automatically ensuring lights and electronics are turned off.


From toasters to fridges to picture frames, the possibilities for networking computerized house household appliances are limited only by your imagination and budget.Your refrigerator can keep track of food expiration dates and act as a family message center via a built-in screen.Coffee makers and other small appliances (such as toasters) can be activated remotely or as part of a sequence of events.You can even imitate Bill Gates and install framed electronic artwork that changes depending on the preference of the person who enters a room,or purchase Internet-connected picture frames that retrieve images from a gallery supplied by your friends and family for a constantly updated family portrait wall.


Energy saving can be realized by automating thermostats,lights and other environmental systems such as garden sprinklers and fountains.

Integrating all of these into one environmental system can help ensure a minimum waste of energy in your home.For example,on hot,sunny day, weather sensors can activate blind and drapery controls to shade your home,and ensure that your garden receivers adequate irrigation at the right time of day.Motion and occupancy sensors can activate heat and lighting controls as you enter and exit rooms.


4.The key to making your home more comfortable,enjoyable and safe through home automation is to follow three essential steps:



Discuss automation needs and wants with your family members so you can plan ahead.Take into consideration your home’s layout in terms of traffic and furniture.



Talk to as many people as possible to get ideas and learn about their experiences with home automation;what worked,what didn’t,what do they had done differently?



What do you definitely want to be able to do?What is optional?Will you install the network yourself or leave it to a professional?What kind of network and what types of technology best suit your needs?Home automation,from security systems to intelligent appliance,is becoming an accessible reality.Whit some careful planning and a little help,you too can enjoy the benefits of a “smart” home.
