[Heat Stroke Obligation Measures] WBGT Warning × Recording × Notification! Watchful-kun PRO
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, due to system reforms, the understanding and response to WBGT values (heat index) have become mandatory for all businesses. "Miharukun PRO" is an IoT solution that visualizes heat stroke risks at work sites, provides immediate warnings, and saves records. 【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>】 ✔ Automatically measures, displays, and records WBGT, temperature, and humidity ✔ Excellent visibility with three-color lights + LCD display (green, yellow, red) ✔ Blinking and email notifications for threshold exceedance → Immediate response possible ✔ Can connect up to 32 child units with one parent unit ✔ Communication via LoRa wireless (long-range, low power, resistant to obstacles) ✔ High-visibility large display warns the entire floor ✔ Log storage can be used for compliance with regulations and report creation
