Why use IoT?
We need to use the Internet of Things (IoT) for many reasons.
1. Automation and Efficiency:
IoT devices can be programmed to perform specific tasks automatically. This helps in increasing efficiency and productivity.
2. Cost Savings:
It can help to reduce costs by automating tasks.
3. Improved Decision-Making:
The data collected by IoT devices can be analyzed to get insights that help in decision-making.
4. Increased Safety and Security:
It can monitor people and other things, which helps safety and security.
5. Convenience:
It can make tasks easy by making them remote-controlled.
How does an IoT System Actually Works?
An IoT device basically uses data from the surroundings or the inputs from the user and then analyzes that data. So firstly, sensors collect data from the environment. It could be one sensor or a collection of sensors(called devices). They collect the data, which is used later. Examples of sensors can be GPS, LDR, temperature sensors, etc. Next, the collected data by the sensor is sent to the cloud via some connection. These connections can be WiFi, LAN, satellite, Bluetooth, etc. Once the data reached the cloud, the software reads and analyzes the data according to the program written in it. This typically includes the processing of data to give predictions. Examples of data processing can be reading temperature values, reading weather conditions, processing any image, etc. The most important part of this process is sending this information to the user. This can be done by creating a user inference and showing them the processed data. This includes alerting the users when the temperature becomes high, alerting them about the weather conditions, etc.
Major Components of IoT (Internet of Things)
There are 5 major components of IoT (Internet of Things) - Devices or Sensors, Gateway, Cloud, Analytics and User Interface:
1. Sensors or Devices
Sensors or Devices are basically used to collect and transmit the data and also perform actions based on those data. For example, the sensors can be used for measuring temperature and humidity. There are different types of sensors; here are as follows: Temperature Sensors, Humidity Sensors, Proximity Sensors, Motion Sensors, Light Sensors, Pressure Sensors, Gas Sensors, and GPS Sensors
2. Gateway
Gateway is also a device component that basically acts as an intermediate between the sensors and the central cloud. Gateway is one of the essential components of IoT that offers communication, management, and data processing. Here are some of the functions of Gateway in IoT: Data Aggregation, Communication, Security, Protocol Translation, Load Balancing, and Latency Reduction.
3. Cloud
Cloud in IoT refers to the service that provides the management, storage, and processing of the data that is generated by IoT (Internet of Things) devices. Here are some key aspects of Cloud in IoT: Data Storage, Data Collection, Security, Connectivity, Integration, and Cost Efficiency.
4. Analytics
This is the crucial component of IoT that basically harness the potential of IoT. In analytics, meaningful insights are analyzed that are generated by IoT devices and sensors. There are some functions included in Analytics, such as data processing, machine learning, and statistical analysis. Here are some of the applications of analytics in IoT: Anomaly Detection, Environmental Monitoring, Energy Management, Smart Cities, and Agriculture.
5. User Interface
User Interface, also known as UI in the Internet of Things (IoT) and provides an interface by which the users can interact with the applications and systems. Here are some of the key points in the user interface of IoT (Internet of Things): Data Visualization, User-Friendly Design, Personalization, Remote Management, Integration, Authentication, and Security.
Real Life Example of Working of IoT
In our data to day life, we use many IoT based devices. Some of them are:
-
Nowadays, many people wear smartwatches which is none other than an IoT device. It contains an accelerometer that measures the number of steps taken, detects hand movements, etc.
-
Using (GPS), these devices can determine your location and compute the distances traveled.
-
There are many IoT devices which are now making your home smart. You can lock/unlock you doors using an application. There are many devices designed which has sensors that can detect any type of mishappening in your home, eg: Glass break, smoke, heat, motion detectors, etc.
- Not only this, IoT devices can also help in disaster management. They help in detection of temperature, carbon content in the region. In case of any forest fire, these devices send an alert to the control room, fire department.
There are many more IoT devices that we are using in our daily life like smartphones, smart cars, biometric attendance, face detection lock/unlock, etc.
