Macnica launches "AiryQonnect Heatstroke Prevention Solution," which visualizes and notifies users of hot environments.

Macnica (Headquarters: Yokohama City, Kanagawa Prefecture; Representative Director and President: Kazumasa Hara; hereinafter referred to as Macnica) today announced that it will begin offering "AiryQonnect Indoor air quality monitoring solution Solution," which integrates with a radiant heat sensor, as a new addition to its "AiryQonnect ^*1" air quality monitoring solution service lineup, starting July 22, 2026.

In recent years, with rising summer temperatures and an increase in extremely hot days, the importance of heatstroke prevention in the workplace has become even greater. In particular, in factories and warehouses where air conditioning is not always sufficient, it is important to continuously monitor the hot environment, including radiant heat ^*2 and humidity, which affect the perceived temperature of workers.
Furthermore, on June 1, 2025, the revised Industrial Safety and Health Regulations ^*3, aimed at strengthening measures against heatstroke in the workplace, came into effect. These regulations now require employers who operate in certain hot environments to establish reporting systems to identify workers at risk of heatstroke early on, and to formulate and disseminate measures and procedures to prevent the worsening of symptoms.

Macnica has been providing solutions through AiryQonnect that visualize air quality data such as temperature, humidity, CO2, TVOC, and PM2.5. By combining sensors, wireless communication, cloud, dashboards, and external device integration, its strength lies in transforming invisible environmental data in facilities and work environments into information that can be used by both managers and on-site personnel.
We have now added Watty's radiant heat sensors, which are effective in identifying heat stress risks, to our integrated system, enabling us to provide comprehensive support from monitoring the heat environment to issuing warnings on-site. This expands AiryQonnect's service area from conventional air quality monitoring to heat environment monitoring.
This solution supports companies in understanding environmental conditions and quickly notifying on-site personnel when establishing and implementing heatstroke prevention measures, thereby contributing to reducing the risk of heatstroke and creating a safe workplace environment.

■System Configuration Image
The following is an example of the configuration of a heatstroke prevention solution that integrates AiryQonnect, a radiant heat sensor, and a warning light.

■Main Features
1. Visualization of the hot environment, including radiant heat.
This system uses sensors to capture radiant heat, which affects the temperature and humidity at a given site and cannot be fully understood by temperature and humidity alone, thus supporting the assessment of heat stress risks. It is intended for use in environments close to the outdoors, factories with heat sources, and workplaces affected by direct sunlight and equipment exhaust heat.
2. Flexible installation combining Bluetooth and LTE
Radiant heat data is collected from sensors via Bluetooth and transmitted to the cloud via LTE through a Cassia Networks M2000. This configuration is easy to implement even in locations where existing networks are difficult to use, and it readily supports data collection from multiple sensors.
3. Remote monitoring using the AiryQonnect dashboard
Administrators can view sensor measurement data on the AiryQonnect dashboard. By remotely monitoring the status of each site, it supports environmental management that does not rely solely on patrols and visual inspections.
4. Immediate notification to the site via Patlite integration.
When a set threshold is exceeded, the system can visually notify the site in conjunction with Patlite products. This makes it easier for not only managers but also field workers themselves to notice changes in the environment, leading to actions such as taking breaks, stopping work, rehydrating, and reporting to managers.
5. Support the establishment of operational systems for compliance with laws and regulations.
While this solution does not replace the reporting systems or preventative measures required by the revised Industrial Safety and Health Regulations, it contributes to improving the effectiveness of companies' heatstroke prevention measures by supporting the understanding of hot environments, issuing warnings, and managing records.

■ Anticipated Usage Scenarios
• Monitoring of heat stress environments in factories, warehouses, and logistics centers
- Back-office management for commercial facilities, train stations, airports, public facilities, etc.
Heatstroke prevention measures at schools, gymnasiums, and event venues.
- Environmental monitoring in areas where air conditioning is ineffective and around heat source equipment.
Remote monitoring/centralized management for companies with multiple locations

■Future developments
Through AiryQonnect, Macnica visualizes invisible environmental data, including air quality and heat stress levels, and integrates it with various devices to support the creation of safe, secure, and comfortable spaces for facility users and workers. Moving forward, we will continue to expand our solutions, which combine sensors, communication, cloud, notification devices, and external system integration, to contribute to corporate safety and health management, health management, ESG management, and facility operation DX.

*1: "AiryQonnect" is Macnica 's Indoor air quality monitoring solution service, combining "Air Quality," which represents air quality, and "Connect," which means that various devices work together. It acquires air environment data such as temperature, humidity, CO2, TVOC, and PM2.5 using sensors, and supports the visualization and management of the indoor environment through wireless communication, cloud, dashboard, and API integration.

*2: Radiant heat is heat that is transmitted without air through sunlight or from high-temperature equipment or walls. Even at the same ambient temperature, the perceived temperature rises in areas with strong radiant heat, increasing the risk of heatstroke.

*3: For details on the enforcement of the ministerial ordinance amending part of the Industrial Safety and Health Regulations, please see the website.
