What is IoT? How it works?
- The Internet of Things (IoT) is a network of physical objects—"things"—embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet.
- The Internet of Things, or IoT, is a new technology that will turn common devices into an ecosystem that will enrich and simplify our lives.
- The Internet of Things (IoT) is the most recent technology that can turn any electrical gadget into a smarter one.
- IoT harnesses the power of data to give users with useful insights that can be utilized to boost operational efficiency and productivity.
- With the aid of IoT, anything from washing machines to ventilators to TV systems to automobile garages may be converted into smarter devices.
- IoT technology is bringing a wide range of everyday products into the digital realm, allowing us to live smarter and more efficient lives.
The components of an IoT system that make it more efficient are as follows:
- Sensors.
- Micro-controller.
- WiFi Module.
- Cloud Platform.
- Actuators.
Sensors:
- These are electrical gadgets that can continuously monitor specified values. The DHT (Digital Humidity and Temperature) sensor, for example, monitors temperature and humidity changes in the environment in real time and sends the information to the microcontroller.
- LDR (Light Dependent Resistor), Soil Moisture Sensor, PIR (Passive Infrared) sensor, Water Flow sensor, and more sensors are available.

Micro-controller:
- This serves as the system's brain, processing the information from the sensor.
- The microcontroller may be programmed to do certain functions. The Arduino Uno and Raspberry Pi are the most widely used microcontrollers.
WiFi Module:
- This makes it easier to connect the gadget to the cloud platform. With the aid of this module, data will be delivered to the cloud platform.
- The ESP-8266 is the most widely used WiFi module.
- Because the Raspberry Pi comes with a built-in WiFi module, you won't need to buy one separately.
Cloud Platform:
- The way data is handled is what sets the Internet of Things apart from previous technologies.
- IoT makes it simple to transport data to the cloud for storage and analysis.
- To do so, you'll need to connect the project to a cloud platform.
- The most often utilized cloud platform is the ThinkSpeak IoT platform.
Actuators:
- These are the devices that respond to orders from the microcontroller by performing a specified activity.
- A machine component or system that moves or regulates a mechanism or system is known as an actuator.
- Actuators such as water pumps, relay driver modules, and DC motors can be programmed to perform various actuations such as irrigating a field, switching on/off devices, and so on.

Features of IOT
- Connectivity.
- Sensing.
- Active Engagements.
- Dynamic Nature.
- Intelligence.
- Safety.
- Integration.
- Ecosystem.
Connectivity:
- It is the most essential quality to consider. It is impossible to perform any task without smooth communication among the interconnected components of the IoT ecosystems (sensors, compute engines, data hubs, and so on).
- Radio waves, Bluetooth, Wi-Fi, Li-Fi, and other technologies can be used to link IoT devices.
- In order to enhance efficiency and provide generic communication across IoT ecosystems and industry, we may use several protocols of internet connectivity layers.
- In other circumstances, the IoT ecosystem may be established on-premises or within an intranet.
Sensing:
- We humans have a natural capability to learn and assess our surroundings based on our previous knowledge with various items or situations.
- To get the most out of IoT, we need to read the analogue data and transform it in a way that allows us to gain important information from it. To collect data depending on a specific problem, we utilize Electrochemical, gyroscope, pressure, light sensors, GPS, Electrochemical, pressure, RFID, and so on.
- Light detection sensors, as well as pressure, velocity, and imaging sensors, are used in vehicle applications. We must select the appropriate sensing paradigm to make a use case successful.
Active Engagements:
- By establishing an active interaction between them, IoT devices link multiple goods, cross-platform technology, and services.
- We leverage cloud computing in block-chain to create active interactions amongest IoT components in general.
Dynamic Nature:
- The first and most important step in every IoT use case is to gather and process data in a fashion that allows business choices to be made from it.
- Throughout this process, many IoT components must alter their states on a regular basis.
- A temperature sensor's input, for example, will change over time depending on weather conditions, location, and other factors.
- This is something that IoT devices should be developed with in mind.
Intelligence:
- The intelligence element of IoT devices' sensing capabilities and the intelligence acquired through big data analytics (also artificial intelligence).
- On the other hand we can say to quick react on the basis of gathered data.
Safety:
- Security is one of the most important aspects of the IoT ecosystem. Sensitive data is delivered from endpoints to the analytics layer via connection components throughout the whole cycle of an IoT ecosystem.
- To protect data from misuse and manipulation, we must adhere to adequate safety, security measures, and firewalls while creating an IoT system.
- Any component of an IoT ecosystem that is compromised might eventually cause the entire pipeline to crash.
Integration:
- To improve the user experience, IoT incorporates multiple cross-domain models. It also guarantees that the infrastructure and operating expenditures are properly balanced.
Ecosystem:
- The Internet of Things' position in relation to other technologies, communities, and aims, as well as the larger picture into which it fits.
- The Internet of Everything, the platform dimension, and the necessity for strong relationships are all factors to consider.
