IoT in Smart Home

Spread the love

The Internet of Things is changing simple homes into smart homes, where everything from your lights to your locks can be controlled from your smartphone, windows, thermostats, water system and more. A world where all of these devices can be in constant communication and controlled by users remotely via voice command or the simple push of a button. The smart home/office gadgets interact, seamlessly and securely; control, monitor and improve accessibility, from anywhere across the globe. The home heating devices are able to control the temperature with the devices like laptops, tablets or smart phones and all of these appliances, systems, and devices contain sensors that connect them to a network. The beauty of the Home Automation system lies in the fact that the settings are manageable from your smart phones and other remote-control devices. Smart home IoT devices can help reduce costs and conserve energy. For this system we use an AVR family microcontroller. This microcontroller is interfaced with a wifi modem to get user commands over the internet. Also we have an LCD display to display system status. The idea of a Smart Home is not new. Back in 1923, Swiss-born architect Le Corbusier described a house as “a machine for living in.” Since then, we have seen many attempts to transform this vision into reality but in most cases adoption was limited to do-it-yourself enthusiasts. A number of startup companies are applying the same approach to control sprinkler systems that water our lawns. These systems gather local temperature and moisture information and use weather forecasts to determine if the lawn needs to be watered and how much water they should use.


Smart home  components

The hub: The heart of your smart home

Simply put, the smart hub is a device that sits at the heart of all device and utilities-related operations in a smart home. The hub is usually controlled via a smartphone app, and uses smart sensors to control all devices-lamps, air conditioning, door locks, kitchen appliances

Security System

Having a smart home requires full security since this is vital to keep you and your property safe from harm. Having a security system installed in your home includes installation of wired surveillance cameras, motion sensors, smoke detectors, fingerprint or eye scanners

Sensors: Keeping your home on its toes

Sensors play the crucial role of automating various parts of the house, as well as the utilities and appliances they contain. Six basic sensors exist in the world of smart homes viz., a Motion Sensor, a Water Sensor, a Doorbell Sensor, a Temperature Sensor, a Light Sensor and a Weather Sensor. As the name suggests, a sensor literally senses elements it’s meant to, and functions accordingly.


Smart home technology gives full credit to communication as a key tool in keeping the house safe and sound. With telephones & intercoms installed all around the house, communication won’t be a problem.

Cloud: What keeps it all afloat

The Cloud is the platform upon which all the devices of the smart home environment interact. It is the space through which you can interface with your smart applications as well as your control their usage as per your requirements. Some of the key players in the growing cloud platform segment today are Samsung Home Cloud API, Cosesy Cloud and IntelliVision.

 Automated Appliances and Furniture

Smart home systems offer voice-automated appliances such as motorized shades and blinds, entertainment systems, lawn sprinklers, and even lights. Having these automated appliances at home relieves you of the laborious tasks especially when you are already old. Voice recognition software products are made available for smart home owners to easily program simple commands to your smart home.

Remote: For your control

Imagine operating your entire home while relaxing on the couch.That’s the smart home remote for you: your very own smartphone or tablet. All you need is a bunch of home appliances, facilitator components, your phone/tablet, and you’re all set!

Smart devices: Thy will be done

Smart devices are the actual appliances in your home. They are designed specifically to connect and communicate with other devices in the house, as well as your remote.

Sensors to help you create a smart home

Fire/CO detection

Fire is far and away the number one cause of property damage. For years the humble fire detector has been beeping away at the first sign of smoke in the home, but there are several types of pollutants that can threaten our home environment and air quality.A carbon monoxide detector measures levels of CO in the air and will warn people if levels are dangerous. Some new sensors not only detect both smoke and CO, but also can monitor the overall air quality in your home and watch for pollutants like dust, soot, pollen, temperature, humidity, air staleness, pollution, and particulates.

Leak/moisture detection

A moisture detection sensor can give you a heads up if your home is at risk due to freezing pipes, or even a broken waterline. These sensors alert you to leaks in your home so can fix the problem immediately and not after the damage has been done. The sensor can be placed around water heaters, dishwashers, refrigerators, sinks, sump pumps and anything at risk for water leakage. If the sensor detects unwanted water a notification is sent to you, so you can hurry home to check out the problem.

Window & door open and close

Door and window sensors let you know when people are entering and leaving your house and can even turn lights on and off as doors are opened and closed. Door and window sensors are your first line of defense for home break-ins; some sensors even detect when a window is broken by an intruder. These sensors alert you to potential intruders, not to mention a deviant teenager.

Lux Sensors

Lux sensors measure the luminosity and can be used to trigger various functions range from cross-validating movements to turn the lights on if it becomes too dark. Some of the most popular light sensors are TSL2591 and BH1750.Recent tests to include TSL2591 and BH1750 into low-powered IoT devices have found them to be working fairly well for most use cases.

 Sound Detection

Sound detection plays a vital role in everything from monitoring babies to automatically turning lights on and off to automatically detecting your dog’s sound at the door and opening it up for your pet.Some commonly used sensors for sound detection include the SEN-12462 and EasyVR Shield for rapid prototyping.

Video Cameras for Surveillance and Analytics

A range of webcams and cameras specific to hardware development kits are usually used in such scenarios. Hardware with USB ports offer to integrate camera modules to build functionality.But utilizing USB ports is not very efficient, especially in the case of real-time video transfer or any kind of video processing.

Applications of Home Automation

Some of the areas where consumers can expect to see home automation led IoT-enabled connectivity are:

  • Lighting control
  • HVAC
  • Lawn/Gardening management
  • Smart Home Appliances
  • Improved Home safety and security
  • Home air quality and water quality monitoring

Disadvantages Of Home Automation

Equipment and installation costs

The more advanced the system; the cost of the system will be very high as it has the more advantages and more new features.

Learning Curve

You will have to adapt to new technology, whether you are comfortable with it or not. Once you do, access to every device you need at your fingertips. The benefits of convenience are yours, but you need to learn how to reap them.


Technology can create disasters if it falls into the wrong hands. Hackers can break into your home once they obtain the password to your lock. Further, you may encounter privacy issues if your camera captures unwanted footage of your neighbour. To avoid such problems, transfer your video via wireless to other areas which you can monitor.

Human errors

If the human does not handle the kit safely or if he/she does not use the correct keys to perform the operations, human errors may occur. Human errors also lead to destructions of the machine. Then there will be a huge system crash.
