LoRa Wireless Remote Monitoring and Control Device WD100 Series

The Miura City Hall is implementing measures to prevent vaccine disposal by utilizing the "Ultra-Low Temperature Freezer Monitoring Solution," a system that automatically monitors temperature abnormalities and power failures in freezers used for storing COVID-19 vaccines. This initiative is featured on their website. The introduction of a system that monitors both temperature and power is a rare effort nationwide. <Purpose of Implementation> To monitor temperature and power abnormalities in freezers and ultra-low temperature freezers (deep freezers) storing COVID-19 vaccines, in order to prevent vaccine disposal accidents caused by power outages, equipment malfunctions, or human errors. <Results of Implementation> The system operated during power outages, allowing vaccines to be stored without compromising quality. Additionally, the vaccine storage environment (internal temperature and power abnormalities) can now be monitored from smartphones and PCs, leading to reduced work time for staff and improved operational efficiency. <Freezers monitored by the system at Miura City Hall> - One unit from Japan Freezer Co., Ltd. - One unit from PHC Corporation *For details about the system, please refer to the product PDF. *For more information, visit our company website or the Ipros introduction page. <Note 1> A 270W freezer with standard configuration has a backup of 2 hours and 45 minutes. In the case of maximum configuration (with two additional battery units), a backup of 5 hours and 5 minutes is possible.

ISAI Corporation has developed a high-function version of a carbon dioxide concentration measuring device, the "Indoor Environment Measurement Monitoring Device Miru-kun PRO <WD100-ENV-LCD>", which contributes to infection control and productivity improvement, and will start sales on January 21, 2022. This product displays the measured values of indoor temperature, humidity, and carbon dioxide (CO2) concentration on a large LCD screen, while visualizing the environmental conditions with three colors of light according to different stages. It notifies users via email or alerts when ventilation is needed. Data is transmitted to a higher level using LoRa, a representative wireless communication method of LPWA, for visualization and analysis. A compact version model without an LCD <WD100-ENV> will also be released simultaneously. Both models allow for quick startup from installation, enabling measurement, monitoring, and countermeasures to begin in a short period. When combined with an additional contact input/output unit, it is also possible to coordinate and control ventilation systems. Up to 32 child devices can be connected to one main unit, and the communication between the measuring unit and the main unit uses LoRa wireless communication, covering areas and obstacles where Wi-Fi or Bluetooth cannot reach. It is also ideal for environmental monitoring in large factories and facilities.

Currently, ultra-low temperature freezers (deep freezers) are used for storing COVID-19 vaccines, but accidents continue to occur due to human errors such as incomplete door closures or unplugged power cords, as well as malfunctions of the deep freezers themselves, leading to temperature increases and the disposal of valuable vaccines. As one of the countermeasures, power backup solutions such as batteries or UPS systems are being offered by various companies; however, issues remain regarding forgotten closures of freezer doors and malfunctions of the freezers themselves, which cannot be resolved by power backup alone. In response, ISA will begin offering a dual-layered solution called the "Ultra-Low Temperature Freezer Monitoring Solution" starting August 10. This solution includes constant automatic measurement and monitoring of internal temperatures via long-range wireless communication, allowing for early detection of temperature increases and providing alerts and notifications through emails and warning lights. Utilizing years of experience, accumulated know-how, and development technology in the IoT field and power management sector, we aim to contribute, even in a small way, to alleviating the chaos and damage caused by the spread of the novel coronavirus.

As we approach the upcoming autumn and winter season, it is very important to monitor carbon dioxide levels and implement ventilation measures not only for the prevention of COVID-19 but also for infectious diseases such as influenza. Additionally, increases in temperature, humidity, and CO2 levels in classrooms can hinder learning efficiency. Knowing the right timing for ventilation is crucial for creating a comfortable learning environment. At ISA, we are conducting a campaign sale of indoor environment (CO2 concentration + temperature and humidity) monitoring sets to support hardworking students. If you inquire during the campaign period, we will conduct a free on-site survey, including a communication test. ■ Indoor Environment (CO2 concentration + temperature and humidity) Monitoring Set [For Educational Facilities × Ventilation Promotion] consists of a main unit + sub-units (with sensors). Up to 32 sub-units can be connected. - Main Unit (WD100-S32/N32): Data collection and communication control server - Sub Unit (WD100-THC): Temperature and humidity/CO2 measurement unit (with sensor) [Usage Image] Install measurement sensors (sub-units) that do not require power in each classroom, and collect measurement data at the main unit in the staff room or management office. Since CO2 concentration and temperature and humidity data can be monitored remotely in bulk, measures to improve the indoor environment can be initiated immediately. <This campaign has ended>
