IoT refers to a set of physical devices, which are connected to the internet. Specialty is they have a little amount of processing power, yet they have the ability to transfer data over a network without the human-human or human-computer interaction. Sensors connected to these devices can collect data. These devices can be connected to both local area networks and wide area networks. We can connect both inanimate and living organisms to IoT networks. It might include plants, animals and also humans. A an example, we can monitor cows in illness and behavior in herd from radio positioning tags. Wearable digital health band such as Fitbit is available for people. Cisco has widened the definition as Internet Of everything as it includes people, places and objects. Anything that you can attach a sensor, and be connected can participate in the new connected ecosystems.

The physical devices which can be connected can have one or more sensors. Sensors may monitor temperature, humidity, motion, location and vibration. These data will provide new information. The data transferred over IoT is small and frequent than traditional computing. Devices connected are also larger when compared to traditional computing.

IoT communicates information to people and systems. Some systems will give data such as state and health of an equipment (e.g.it’s on or off, charged, full or empty) Some systems with sensors can monitor a person’s vital signs. For example, an IOT-enabled HVAC system can report if its air filter is clean and functioning properly. Almost every company has a class of assets it could track. GPS-enabled assets can communicate their current location and movement. Location is important for items that move, such as trucks, but it’s also applicable for locating items and people within an organization. In the healthcare industry, IoT can help a hospital track the location of everything from wheelchairs to cardiac defibrillators to surgeons. In the transportation industry, a business can deliver real-time tracking and condition of parcels and pallets. For example, Maersk can use sensors to track the location of a refrigerated shipping container and its current temperature. Iot devices can be remotely controlled and can be automated. IoT saves money from equipment failure and maintenance. New smart matters in home are developed as a remedy for the issues of energy consumption.

Steps in building up a IOT system

1.Defining what type of data we get from sensors

2. We need to track a particular data  for our processing .So we have identify the data and sensor first.

3. Building an IoT network and security foundation

4. We have to connect IoT devices with  standard-based IP networks.security issues also should be considered.

4. Collect as much as data possible.

5. We have to use a number of sensors as one sensor can collect little amount of data.

6. Consider the size and scale of IoT providers

7. Consider the financial position of vendors ,industry knowledge and partnerships.

IOT systems play a major role in the present technological world. More amazing systems will come up in no time, with further developments to this trending technology.
