How do IoT devices communicate? Communication protocols for connecting IoT devices functions at this point. Wireless protocols including Wi-Fi, Bluetooth, LTE, and ZigBee, as well as wired protocols like Ethernet, Modbus, and KNX, are frequently used to link IoT devices.

Wired IoT devices usually refer to devices connected to the network through network cables, which are commonly found in industrial settings, such as industrial gateways, converters, industrial robots, security cameras, and so on. They are connected to the network using network cables. Wireless IoT devices connected to the internet through 4G, WIFI, Bluetooth, etc., which widely used in daily life and business fields, such as smart home gateways, smart speakers, and smart office appliances.

How Do IoT Devices Work?

Although the functionality of IoT devices varies, there are certain commonalities in how they operate. IoT hardware itself consists of integrated CPUs, network adapters, and firmware that is frequently created using open-source software. Let’s examine the key elements of IoT and how they function as a whole.

IoT Smart Sensors

IoT workflows begin with sensor devices, which are field hardware used to gather data from the environment. A sensor is a device that monitors and responds to input from the physical world. The specific input may be light, heat, motion, moisture, pressure, etc., and the output is usually directly converted into human-readable information on the sensor, or through the network in digital form.

IoT sensors and other devices transfer data wirelessly to IoT gateway using the same protocol. Once the gateway get the data, they can use Ethernet, WiFi, or LTE to relay it to the rule engines, which are often housed in private or public clouds.

Data Processing

IoT devices produce enormous volumes of data in a variety of forms, and before the data can be used for any type of analysis or processing, some processing must be done on the data:

  • standardize data or transform data into a uniform format that works with your application;
  • store or create backups of newly converted format data;
  • Filter any redundant, outdated, or unwanted data to improve accuracy;

Edge computing can analyze and process data using on the IoT edge, speeding up network service responses and addressing the fundamental requirements of businesses requiring real-time responses, artificial intelligence, security, and privacy protection. Smart devices for edge computing can be IoT terminals with special processing capabilities, or edge computing gateways or routers with certain data collection and data computing capabilities.

Types of IoT Devices

Each IoT device communicates with other related devices in the environment to enable remote monitoring, automated management, and other household and industrial tasks. According to user groups, these IoT devices can be divided into three major categories: consumer, enterprise, and industrial IoT devices.

For Consumers

Smart TVs, smart speakers, wearables, and smart appliances are just a few examples of IoT devices widely used by individual consumers. Take smart home as an example, IoT devices are made to sense and react to human presence. A person’s automobile interacts with the garage to open the door when they get home. Once inside, the lighting is tuned to a lower intensity and hue because their wristwatch data suggests it is a stressful day, and the thermostat has been set to its optimal setting. Other smart home appliances include robot vacuums that can figure out which rooms in the house need to be cleaned the most frequently and sprinklers that regulate watering based on the weather prediction.

For Enterprises

There will be some overlap between consumer and corporate IoT devices, such as smart locks, thermostats, lighting, and security, but enterprise IoT devices often focus more on facility maintenance or increasing operational effectiveness.

For example, smart devices can help companies hold meetings. Employees may use smart sensors installed in meeting spaces to detect and schedule rooms that are open for meetings, ensuring that the ideal room type, size, and function are available. The temperature will change as participants enter the space, the lights will darken when the relevant slide presentation loads on the screen, etc.

For Industrial Automation

Industrial IoT devices are intended for use in manufacturing factories or other industrial environments. The majority of IIoT devices are sensors that keep an eye on production lines and other manufacturing operations, in order to make sure crucial operations are functioning as efficiently as possible. Data from various sensors may also help prevent unplanned downtime by predicting when parts will need to be replaced.

Benefits and Drawbacks of Using IoT Devices

One cutting-edge technology is the Internet of Things. It can employ a variety of Internet of Things devices to create a very big Internet of Things system, allowing data to be gathered, transmitted, and monitored in real time at any time by the Internet, and the information is able to be output automatically. That is to say, IoT devices can effectively monitor and automatically operate a variety of physical devices to efficiently perform tasks like remote connectivity, data collection and automated control.

In smart agriculture, IoT devices like smart sensors can collect information about soil composition, temperature, humidity, rainfall, and other variables and transfer data to back-end cloud servers, so as to facilitate the agricultural automation, helping farmers simplify their work.

Things to Consider When Purchasing IoT Devices

Businesses in all sectors are ncreasingly leveraging IoT to improve operation efficiency, better understand their clients, and deliver better customer service to support decision-making and boost corporate value. Various IoT devices form a network to exchange data without human-to-human or human-machine interaction. So what factors should businesses consider when buying IoT devices?


The first thing to think about before investing in IoT devices is how to connect it to the Internet and cloud computing platforms, which largely depends on the environment in which the devices will be installed and the type of communication infrastructure provided to them.

For instance, if you’re creating a IoT-enabled washing machine for smart home ecosystem, you may have access to a Wi-Fi home network or a ZigBee/Z-Wave IoT router. As a result, your washing machine has to support one or more transmission medium. Also, in some environments, such as remote areas, where Wi-Fi networks are not accessible, cellular networks may be your only possible connection option. Therefore, you must weigh your options and make decisions based on possibilities and investment that each option presents.


Physical Security

IoT devices are frequently found outside, unsupervised, and unprotected. You must make sure they can’t be deliberately modified with. You should also think about securing any form of data that is kept on the device. It is crucial to encrypt data on the device even if it is expensive to include security protection components in every IoT device.

Data Security

The simple way to transfer data to the cloud is to transmit the data between the device and the IoT sensor to the gateway, in order to accomplish the transmission and delivery of information. The answer to enhance IoT gateway security is already previously provided in the article.

Firmware Update

To prevent security holes, you hava to harden your product code and hardware consistently. In this case, you first need to have a plan for fixing bugs and rolling out patches quickly (rather than letting bugs live for a long, long time). Over-the-air updates are a popular mechanism for updating connected devices.

Future Proofness

Many technologies in use today are likely to become obsolete in the future. Therefore, IoT device durability and the time interval between replacements are additional factors to take into account. For instance, smart home appliances often need to be durable for at least five to ten years.

Ensuring that IoT devices can support future technologies requires designing products with the right balance of both software and hardware. Specialized hardware may produce the highest performance when making IoT devices, but it may also limit future product improvements.

Additionally, you may pick an operating system tailored particularly for the Internet of Things, like Linux, the appropriate quantity of storage and processing resources, and the suitable amount of computing power to enable more flexible expansion of devices to add new features and carry out patch updates. Dusun IoT is an expert in IoT hardware that can be programmed, enabling developers to increase the functionality of existing devices. We’ll offer APIs and SDKs when you make IoT hardware development.


It is important to think about compatibility before purchasing IoT devices. Your IoT devices may need to connect to more IoT device items and interact with them. If the device compatibility is strong, it will guarantees that your IoT devices integrate with your IoT ecosystem without complication or frustration. Zigbee devices are recommended by Dusun IoT, because the standard Zigbee 3.0 protocol ensures better interoperability.

Final Words

IoT devices work together in an ecosystem to automate operations by communicating with other similar devices in the environment. IoT devices may deliver effective system performance, raise the bar for industry intelligence, and and realize functions such as remote monitoring and intelligent control that save time and effort. It may be claimed that IoT devices are a useful tool for autonomous management, injecting new vitality into the growth and development of businesses and society.
