Intelligent Health Vigilance System Using Internet of Things (IoT)

What Is Iot?

IoT is exchange or communication of data between different objects or devices that are connected to each other through internet. IoT helps in establishing connectivity between different devices and objects through the usage of internet.

IoT is a link which helps in attaining all the necessary data and information about the connected device or object that one would require to know. It makes the information and data of the connected device or object available at just one click. It actually bridges the gap between the things connected through it.

IoT removes barriers of distance by connecting devices and objects virtually and wirelessly through internet without the need for the devices to be physically present in front of each other. The users can control and access their IoT connected devices from any location in the world. This gives the users a great flexibility and proves as a major advantage.

Working Of Iot

The IoT working is a simple process. It involves contributions from sensors and cloud. The working process is initiated by sensors. The sensors gather all the information and data from its surroundings. This data is safely passed on to the cloud for processing. After processing of data, it is available for the user to view. The user also has the facility to intervene and control the IoT process. The working of IoT can be considered as a fixed flow of events taking place one after the other. For better understanding, the working of IoT can be considered in parts. The first part is action of sensor.

• 1.

  Action of Sensor: The sensor’s job is to sense all the possible data from its vicinity. The sensor acts even on a very negligible change happening in its vicinity and always actively keeps on sensing each and every change happening in its range.

• 2.

  Preparation for Sending Data to Cloud: The sensor has all the data it has received through sensing. The data is in raw form and this data collected from the sensor needs to be sent to the cloud. The sensor makes preparation for sending the data collected to cloud by ensuring all the data remains unaltered and in it exact raw form in which it is collected.

• 3.

  Transition to Data Processing Stage: The data undergoes a lot of changes after transition to data processing stage. The raw data is processed and after being processed it is ready to be sent to the user.

• 4.

  Empowering the User: The user can at any time and from any location view and access the data of the device or object connected through IoT. The user is also empowered with the ability to control the device or object connected through IoT.
