[For Work Sites] WBGT Value Displayed in Three Colors + Visualization Product for Heat Stroke Risk
Watchful-kun PRO <WD100-ENV Series>
Heatstroke prevention measures made mandatory! An IoT warning system that measures and records WBGT, ensuring visibility and notifications to protect the workplace.
In 2025, a system reform mandated that all businesses must understand and respond to WBGT values (heat index). "Miharukun PRO" is an IoT solution that visualizes, provides immediate warnings, and stores records of heatstroke risks at work sites. 【This product solves the following issues】 ✔ Heat measures at the site are subjective and vague ✔ WBGT values for each site are not being monitored ✔ Warnings are not noticeable, and employees may not be aware ✔ Records are not kept, making management and reporting difficult 【Main features of Miharukun PRO <WD100-ENV-LCD>】 ✔ Automatic measurement, display, and recording of WBGT, temperature, and humidity ✔ Excellent visibility with three-color lights + LCD display (green, yellow, red) ✔ Flashing and email notifications for threshold exceedance → Immediate response possible ✔ One main unit can connect with up to 32 sub-units ✔ Communication via LoRa wireless (long-range, low power consumption, resistant to obstacles) ✔ Large display with high visibility warns the entire floor ✔ Log storage can be utilized for compliance and report generation

Applications/Examples of results
With the "mandatory" implementation of WBGT monitoring and heatstroke prevention measures on-site, there is an urgent need to introduce a system that can be operated immediately. "Miharukun PRO" eliminates the need for extensive wiring through LoRa wireless communication, allowing it to be installed in various locations within factories, warehouses, and buildings. 【Practical Examples】 ✔ Safety management for construction sites and warehouse operations in hot environments ✔ Automatic WBGT monitoring in factory floors without air conditioning ✔ Establishment of a management system that responds promptly to revisions in labor safety and health regulations ✔ Promotion of voluntary actions by workers through highly visible LCD displays ✔ Utilization of log data for report submission and risk management
