[Heatstroke/Ventilation Measures] Temperature and Humidity CO2 Concentration Measurement & Watchman Pro Issues Warnings
Measure indoor temperature, humidity, and CO2 concentration, and display it on a large LCD screen. Warn with three colors of light in stages and notify about ventilation via email or alerts!
The monitoring targets selected by the user from temperature, humidity, carbon dioxide (CO2) concentration, and WBGT (heat index) are indicated by a three-color LCD: green for "normal," yellow for "caution," and red for "warning/ventilation needed immediately." For example, if "standard values" suitable for avoiding crowded places or ensuring a comfortable indoor environment are preset, the color changes as the status escalates, and the displayed measurement values will blink to provide a warning, along with email notifications. Temperature, humidity, and carbon dioxide (CO2) concentration are measured using high-precision sensors built into the measurement unit, and the measurement data is collected by the main unit. Up to 32 sub-units can be connected to one main unit, and the communication between the measurement unit and the main unit uses LoRa wireless communication, which is resistant to obstacles and enables long-distance communication with low power consumption, covering areas and obstacles that Wi-Fi or Bluetooth cannot reach, including across floors and distances. This makes it suitable for environmental monitoring in large factories, facilities, and buildings. ★ Measures and displays temperature, humidity, carbon dioxide (CO2) concentration, and WBGT (heat index) ★ Alert notifications via email, etc. ★ Utilization of WBGT values for heatstroke prevention ★ Can be combined with contact input/output units for integration with ventilation systems
basic information
The "Miharu-kun PRO <WD100-ENV-LCD>" features a large, highly visible LCD display that allows for easy monitoring from anywhere in the indoor space. It clearly indicates the timing for ventilation, contributing to cost reduction and energy savings. The secondary effects of ventilation also help prevent issues such as decreased concentration, drowsiness, and headaches, thereby contributing to a healthy indoor environment by addressing infection control and improving productivity. 【Main Unit】Data Collection Communication Control Server Model Number: WD100-N32 (without LTE) / S32 (with LTE) *Separate contract with communication carrier required 【Sub Unit】Measurement Unit Model Number: WD100-ENV-LCD <Model with Display> 200 (W) × 200 (H) × 40 (D) mm Model Number: WD100-ENV <Model without Display> 75 (W) × 100 (H) × 35 (D) mm

Immediate response to the "Heat Stroke Warning Alert"! Urgent proposal of heat stroke prevention products that can be used on-site right now.
In response to the "Special Heat Stroke Warning Alert" and the "Mandatory Heat Stroke Measures" that began full-scale operation in June 2025, we are reintroducing our IoT heat stroke countermeasure solutions. The target products are the three series: "Meru Maru-kun + Heat Stroke Alert," "Miharukun PRO," and "Momoko and Ayaka." With this system revision, heat stroke measures have changed from "effort obligations" to "obligations" for all businesses employing workers. As measures are required across all industries and sites, including government agencies, educational institutions, welfare facilities, distribution, and construction, ISA supports the creation of a safe and secure environment through existing products that can be operated immediately. ■ Introduction of three heat stroke countermeasure products (1) Meru Maru-kun + Heat Stroke Warning Alert Email Distribution Service (2) Miharukun PRO (WBGT compatible model) (3) Momoko and Ayaka Environmental Monitoring Solution (environmental monitoring, recording, alerts) ◆ Main industries and achievements of implementation Local governments (offices, evacuation centers, nurseries) Educational institutions (playgrounds, gymnasiums, classrooms) Medical and welfare facilities (nursing homes, disability support facilities) Distribution and construction industries (warehouses, job sites, delivery hubs) General companies (reception areas, warehouses, employee break rooms)

Case Study: Miura City Hall, Kanagawa Prefecture - Introduction of "Ultra-Low Temperature Freezer Monitoring Solution" to Prevent Vaccine Waste ★ Monitoring of Freezer Temperature & Power Supply + Power Backup System (Note 1)
Utilizing the "Ultra-Low Temperature Freezer Monitoring Solution," a system that automatically monitors temperature and power abnormalities in freezers for storing COVID-19 vaccines, the Miura City Hall is implementing measures to prevent vaccine disposal. This initiative, which involves the introduction of a system that monitors both temperature and power, is one of the few of its kind in the country. <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, and 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 checked from smartphones and PCs, leading to reduced work hours 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> With a 270W freezer, the standard configuration provides 2 hours and 45 minutes of backup. In the maximum configuration (with two additional battery units), it can provide 5 hours and 5 minutes of backup.

At ISAI, we offer a range of monitoring solutions including network warning lights (Keiko-chan / Meru Maru-kun), network monitoring, contact monitoring, PDUs, and network UPS, as well as IoT solutions for agriculture, distribution, factory automation, food, pharmaceuticals, education, and healthcare utilizing LoRa wireless communication. In the UNIX era of the 1990s, we developed an automatic shutdown device as a countermeasure for shutdown processing troubles. Subsequently, we focused on the development of network-related devices centered around Embedded Linux, and in the 2000s, we announced various networked devices and integrated management solutions. Even now, through unique products such as intelligent UPS, network warning lights, and LoRa wireless-enabled sensing systems, we provide advanced technology in a safe and easy-to-use manner, contributing to the enhancement of IT infrastructure. Additionally, ISAI leverages its achievements in server power management and automated system operations in large-scale core systems to offer a wide range of system operation technologies, including remote monitoring, equipment control, and the operation, monitoring, and management of power supplies (including UPS) via network.
