Single-Board Computer (SBC) can perform various functions in IoT

The architecture of IoT (Internet of Things) is typically divided into three layers, each with its own distinctive function:

Perception Layer: This layer relies primarily on intelligent devices, sensors, and other endpoints that gather data from the physical world. The data collected from these devices is typically raw and unprocessed.

Network Layer: This layer encompasses the communication infrastructure, protocols, and gateways that connect the devices in the perception layer to the cloud or other computing resources, primarily achieving the function of transmission.

Application Layer: This layer includes cloud-based applications, analytics, and services that process the data collected from the perception layer. The application layer is responsible for data storage, processing, and analysis, and provides insights, alerts, and other user-facing functionality, which is the ultimate IoT application scenario.

In summary, these three layers collaborate to achieve end-to-end IoT solutions that provide real-time data, analysis, and automation, enhancing functionality, efficiency, and value across various industries and applications. SBCs, being equivalent to a computer, can accomplish data analysis at the application layer, and possess a certain degree of scalability. Some SBCs can also connect with external intelligent devices, making them pivotal in the realm of IoT.

Overall, SBCs can perform many of the same functions as larger servers or cloud-based systems, but on a smaller scale. They are particularly useful for IoT solutions that require edge computing, where data is processed locally, in real-time, and only relevant data is sent to the cloud for storage and analysis.

So, how to choose a single-board computer for IoT?

How to choose a single-board computer for IoT?

Choosing the right Single Board Computer (SBC) for your IoT project can be a daunting task, but here are some factors to consider that can help you make an informed decision:

1. Processing Power:

The processing power of an SBC is an important consideration when choosing an SBC for IoT projects. You need to choose an SBC with sufficient processing power to perform the tasks required by your project.In recent years, edge computing technology has played a significant role in promoting IoT direction. Simply put, edge computing refers to the analysis of data collected from terminal devices directly in local devices or networks close to the data source, without transmitting the raw data to the cloud data processing center. This reduces the transmission of irrelevant data, reduces bandwidth requirements, reduces power consumption, and increases decision-making speed. SBCs can play an important role in data collection and analysis as edge computing devices in IoT solutions.

2. Power Consumption:

As the crux of the Internet of Things revolves around a continuous influx of big data and the incorporation of additional devices into the network, device power consumption assumes pivotal significance.And IoT SBCs may need to be deployed in locations or scenarios where power resources are limited, such as water quality monitoring, oil and gas exploration, earthquake monitoring, etc. By consuming less power, SBCs can operate for longer periods of time.

3. Memory and Storage:

The amount of memory and storage an SBC has will affect the performance of your project. If your project requires high amounts of data storage, consider an SBC with a large storage capacity.

4. Connectivity:

The connectivity options of an SBC are also important. Make sure the SBC has the required connectivity options, such as Wi-Fi, Bluetooth, Ethernet, and USB, and connect to your sensors and other IoT devices.

5. Operating System and Software Support:

The operating system and software support for an SBC are important factors to consider when choosing an SBC for IoT. Choose an SBC that is compatible with the operating system and software required by your project.

6. Cost:

The cost of an SBC is another important factor to consider. Choose an SBC that fits your budget, but make sure it has the required features for your project.If you want an SBC that can handle both network and edge computing, its price will be higher. However, compared to choosing separate network devices and PCs, there is still a higher cost-effectiveness.

Overall, the choice of an SBC for IoT depends on the specific requirements of your project. Evaluate the above factors carefully to choose the SBC that best meets the needs of your project.
