Grid Link Co., Ltd. (Shinjuku, Tokyo), which operates the IoT platform "M2MSTREAM," will begin providing a cloud-based indoor ventilation monitoring system that visualizes the ventilation status of enclosed spaces where people gather by continuously monitoring carbon dioxide levels. 【Benefits of Implementation】 ■ As a measure against the COVID-19 pandemic, it is essential to thoroughly avoid the "three Cs" (closed spaces, crowded places, and close-contact settings). Ensuring appropriate ventilation based on CO2 levels is crucial to prevent commercial facilities from being classified as "poorly ventilated enclosed spaces." ■ According to the air conditioning and hygiene engineering standards, the reference value for necessary ventilation in a room is approximately 30m³ per hour per person. By counting the number of people present using AI cameras, it becomes possible to estimate and secure the necessary ventilation volume based on occupancy density. ■ Low humidity can dry out the mucous membranes of the airways, weakening their ability to prevent bacterial infections. Humidity sensors can manage the lower limit of humidity levels. ■ By displaying air quality information in real-time on digital signage, it is possible to alert space users and alleviate their concerns.

Gridlink Corporation (Shinjuku, Tokyo), which operates the IoT platform "M2MSTREAM," will begin offering a cloud-managed digital signage solution that combines large displays and environmental sensors with IoT systems for the construction industry. 【Benefits of Implementation】 ■ By cloudifying the system, centralized management at the headquarters can be achieved, significantly reducing the workload of site supervisors who are responsible for data collection, management, and reporting. ■ By updating and sharing information daily, the attention and awareness of on-site workers can be enhanced, revitalizing the worksite. ■ By recording objective and continuous data regarding the working environment, proper labor management can be achieved, promoting work style reform. ■ To avoid troubles with neighboring residents, "prior notification" and "frequent communication" are necessary. By actively utilizing highly visible digital signage to facilitate communication, it becomes possible to prevent the occurrence of troubles.
