How do you access information within your company or information in business systems on a daily basis? Do you search on the corporate portal site, open a dedicated dashboard, or look through the file server? This time, I would like to consider the possibilities of "methods of accessing information" from the perspective of something that is becoming increasingly commonplace to use. *You can view the detailed content of the blog through the related links.

As digital transformation (DX) progresses in companies, there is a rapidly increasing demand to incorporate IT technologies into Operational Technology (OT) systems to provide higher value-added services. In particular, in environments such as factories, buildings, and social infrastructure, there is a growing trend to expand systems that have traditionally been completed with control devices like PLCs (Programmable Logic Controllers) to be utilized more broadly and remotely. On the other hand, in the field of IoT, LoRaWAN, which is one of the Low Power Wide Area Network (LPWAN) technologies, is gaining attention. *For more details about the blog, please refer to the related links.

Battery-powered IoT devices have a mechanism that keeps them in sleep mode to reduce battery consumption except during startup. At startup, they consume a peak current of several hundred mA, but in sleep mode, it is in the order of μA. This change in current can be observed with an oscilloscope, but I learned that there is a tool called "Power Profiler Kit II (PPK2)" that allows for longer and simpler data acquisition. *You can view the detailed content of the blog through the related link.

I found an antenna with the interesting name "donut antenna" on AliExpress, so I bought a red one for medium wave and a blue one for short wave. It seems to be a tuning circuit that combines a coil printed on a donut-shaped circuit board with a variable capacitor. It arrived from Shenzhen after about five days of waiting. I installed this antenna on the Si4732 DSP radio I created last time and tried receiving distant signals. *You can view the detailed content of the blog through the related links.

In the world of IoT devices, sensor devices tend to attract a lot of attention. However, the LT22222-L from Dragino, which we are introducing this time, takes a slightly different approach. This device is equipped with two relay outputs and excels in remote control using LoRaWAN, making it a specialist in control systems. It may look plain and lacks flashy features. However, once you actually use it, you will be amazed by its capabilities. *For more details, you can view the blog through the related link. Please feel free to contact us for more information.*

In recent years, against the backdrop of the advancement of sophisticated large-scale language models (LLMs), we have implemented an LLM application aimed at predicting the complex movements of the stock market. By integratively utilizing traditional forecasting methods such as technical analysis, fundamental analysis, and news sentiment analysis, we aim to verify whether investment decisions can be made using AI. *For more details, please refer to the related links.

IoT and printers. At first glance, it may sound like a combination of seemingly opposing technologies. On one hand, there is advanced digital technology, and on the other, a traditional analog output device. However, this combination might just be the solution that is truly needed on the ground. This time, we would like to introduce a solution called "IoT Printer," which outputs data from IoT sensors using a thermal printer—something that seems plausible yet has not existed before. *For more details, you can view the blog through the related link.

In recent years, looking at serious security breach incidents, there has been a sharp increase in cases where intrusions that cannot be prevented by traditional boundary defenses (such as firewalls and antivirus software) are the starting point. What is particularly frightening is the situation where outsiders have infiltrated the LAN without anyone noticing. - Targeted attacks: Malware infections via email attachments or websites - Infiltration into internal networks: Horizontal expansion starting from virus infections - Long-term persistence: Continuing activity for months to years before being discovered - Data theft: Ongoing leakage of internal information Traditional security measures have focused on "preventing intrusions from the outside," but in reality, attackers may already be inside. *For more details, please refer to the related links on the blog.

• Firewall and intrusion prevention

In previous articles, we have introduced the value of deliberately outputting digital data in analog form, such as printing IoT sensor data and physical outputs for security alerts. This time, as the third installment of our "Digital x Analog Fusion" series, we will present an implementation example using the PB05-L from Dragino, which we have recently started handling. *You can view the detailed content of the blog through the related links.
