What Are The Main Part of an IoT System?

How IoT Works

The Internet has changed our lives because we relate to the whole world and sharing information without making a difference in the location.

IoT is operating in a similar way and aims to achieve a degree of connectedness where numerous devices are connected to the Internet to enable interactions between machines and people as well as between machines and other machines.

The people who are working on this idea have deep knowledge of IoT. They know that IoT is not limited to a particular field. It is being used in many fields like home automation, medical and healthcare field, industrial automation, agriculture, and many more. There are four main components of an IoT system that fulfill the objective of making an accurate smart device that can give comfort to its users.

Components of IoT

The IoT system consists of 4 basic components that are crucial for making a smart device. These are as follows:

• Sensors
• Connectivity
• Data processing
• User interface

• Sensors

  One of the fundamental parts of the IoT system are sensors. A gadget would not be possible without a sensor. A sensor is a tangible object used to continuously collect data from its environment. The data may be as straightforward as a temperature reading or it may be sophisticated in varying degrees. For example, it may be a temperature monitor, or it might be a more sophisticated data collection system that includes a complete video feed.

  Multiple sensors that each focus on a separate job may be combined into one box or device to form an IoT device. One such gadget that includes several sensors, including a camera, GPS, accelerometer, and many more is our smartphone. As a result, sensors must always be working and gather reliable data. Otherwise, the results will be incorrect.

• Connectivity

  Now the data that is collected by the sensors is transmitted onto a cloud that needs a medium to travel.

  The sensors need a network to send the data to the cloud. The network can be of any type like satellite network, Bluetooth, Wi-Fi, wide area network, local area network, and many more. Every network has its specifications.

  You have to check the standards for the network you have selected for transmitting the data from sensors to the cloud. You have to make sure that the range is different for every network. So, you should choose the appropriate networks that can match your requirement.

  Choosing the best network medium is the base of the successful IoT system. So first check each of the networks then decide which will work accurately in your environment.

• Data Processing

  It's time to process the data now that it has been gathered and successfully sent to the cloud. Checking the heater or air conditioner's temperature inside a certain range may be fairly straightforward. Finding the intruders at your residence who are employing computer vision on video might be quite difficult at times.

  One thing to bear in mind is that user engagement may be necessary, such as asking you about their thoughts whether the temperature is too high or low. Sometimes the user is not harmed by the high temperature.

  In order to learn about the user's preferences, the sensors communicate with them. The same applies to figuring out who broke into your home. If it discovers an intrusion, it alerts the user of the situation and the need for interaction.

• User Interface

  This is the last part of the IoT system where the user interacts with the application. They can receive an alarm or mail for this purpose. There are also options on some devices where the users can regularly check in their IoT system. Like a user who has installed a camera in his house may want to check all the recordings and videos via a web server.

  Thus, it all depends on the IoT application where the user may perform some actions that can put the whole IoT system in danger. For example, the user can make the changes in refrigerator function by using their smartphone that is remotely connected with it via the Internet. Some applications alert the users and the concerned authorities by sending them a message that there is an intruder around the sensor. So, it all depends on the application you are using.
