The definitive carbon dioxide concentration meter necessary for ventilation measures! Three-color light warning in stages: "Miharukun PRO" released on January 21, 2022.

Measures CO2 concentration, temperature, and humidity, and notifies you when ventilation is needed via email or warning lights (optional)! <High-performance CO2 sensor>

The invisible CO2 concentration, temperature, and humidity are measured, and notifications for when ventilation is needed are sent via email or warning lights (optional). You can install the sensor-equipped subunits in places where you want to monitor the indoor environment (up to 32 locations) and simply set up the main unit in the area you want to manage to start measuring immediately. The indoor environment (CO2 concentration + temperature and humidity) monitoring set supports long-range wireless communication with LoRa, eliminating the need for wiring. It can be easily installed and introduced anywhere. ★ Features of the indoor environment monitoring set - Easy installation - Centralized management - Maintenance-free 10-year battery - Long-range wireless communication (LPWA) with LoRa - Notifications possible with threshold settings * The catalog for the "CO2 + Temperature and Humidity Monitoring Set" can be immediately accessed via "PDF Download." If you have any other questions, please feel free to contact us.

[COVID-19 Measures + Ventilation Promotion] Indoor Environment (CO2 Concentration + Temperature and Humidity) Monitoring Set (Main Unit + Subunits)! Up to 32 subunits can be connected!

Monitoring carbon dioxide levels and linking them to ventilation efforts is very important. Knowing the timing for ventilation is essential for creating a comfortable indoor environment. ■ Indoor Environment (CO2 Concentration + Temperature and Humidity) Monitoring Set [For Educational Facilities × Ventilation Promotion] The set consists of a main unit + sub-units (with sensors). Up to 32 sub-units can be connected. - Main Unit (WD100-S32/N32) Data Collection Communication Control Server - Sub-Unit (WD100-THC) Temperature and Humidity/CO2 Measurement Unit (with sensor) [Usage Image] Install measurement sensors (sub-units) that do not require power in each classroom, and collect measurement data at the main unit in the staff room or management office. Since CO2 concentration and temperature and humidity data can be monitored remotely in bulk, measures to improve the indoor environment can be initiated immediately. By setting thresholds suitable for avoiding close contact and for the learning environment, you can determine the appropriate timing for ventilation!

If the threshold is exceeded, email notifications and warning light alerts will be triggered, enabling efficient ventilation measures within the theater and helping to prevent sealing!

We would like to introduce a case study of the "Indoor Environment Monitoring Set" (high-performance CO2 concentration, temperature and humidity measurement sensors, gateway, and warning light) that has been implemented at Shinjuku K's Cinema (Location: Shinjuku, Tokyo). <Purpose of Implementation> To visualize the air and environmental conditions within the facility and to implement effective ventilation measures and prevent sealing. <Before Implementation> Ventilation measures such as limiting the number of visitors, using the air conditioning system, and bringing in outside air had been taken, but the difficulty of confirming sealing prevention measures visually was felt. <After Implementation> Measurement units (sub-devices) equipped with CO2 concentration and temperature and humidity sensors were placed in five locations where people are likely to gather, and the main unit was installed in the management room. Measurement data is sent to the cloud via the main unit, allowing for confirmation at any time using a PC or smartphone. In the event that the set threshold is exceeded, notifications via email or warning lights enable the implementation of effective ventilation measures, establishing a system for environmental management aimed at ensuring customer safety and security. <Implementation Effects> ■ Visualization of indoor environment (CO2 concentration, temperature, and humidity) ■ Efficient and accurate implementation of ventilation measures ■ Infection prevention through sealing prevention measures ■ Providing safety and security to customers

Contributing to agriculture/FA/dining/HACCP! Easy installation with long-term operation! "Momoko and Ayaka," suitable for data collection and equipment monitoring control.

The WD100 series "Momoko and Ayaka" is a device that allows for the remote collection of environmental information and control of equipment using a wireless method based on LoRa technology. The system is composed of a measurement and control unit and a data collection communication control server. The measurement and control unit is available in various types according to the data and control requirements. It is designed to be waterproof (IP67) so that it can be installed in both indoor and outdoor environments. The data collection communication control server manages the communication of up to 32 measurement and control units, collects data, and performs monitoring and management. It can also be set up to monitor for abnormal values, allowing for notifications not only for abnormal data but also for communication issues, battery life, and more. Additionally, the system can be easily constructed, enabling quick integration with existing systems or cloud services. 【Features】 ■ Measurement units come pre-wired with sensors ■ Maintenance-free and long-lasting ■ Suitable for installation indoors and outdoors ■ Excellent monitoring and management functions ■ Capable of long-distance communication ■ Abundant external connections *For more details, please visit the external site or feel free to contact us.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
