CO2 sensor "COZIR-Blink"

CO2 sensor "COZIR-Blink"

Can be used in dry batteries and battery-powered wireless modules! Ultra-low power consumption CO2 sensor.

The "COZIR-Blink" is a CO2 sensor with configurable measurement cycles and automatic calibration periods. Due to its very short startup time, it is possible to turn off the power immediately after the sensor has taken a measurement. As a result, the power consumption becomes zero outside of the user-defined measurement cycle, making it suitable for applications that require lower power consumption. 【Features】 ■ High-precision NDIR CO2 sensor ■ Digital output via UART and I2C ■ Time required for the first measurement < 3.5 seconds ■ Long lifespan of over 15 years * For more details, please refer to the PDF document or feel free to contact us. * An English version of the catalog is available for download.

CO2 sensor (carbon dioxide concentration measuring device)

CO2 sensor (carbon dioxide concentration measuring device)

A compact CO2 sensor that displays carbon dioxide (CO2) concentration in real-time. It visualizes indoor carbon dioxide levels at one-second intervals.

When the indoor CO2 concentration reaches 10,000 ppm, cognitive ability and concentration decrease. As CO2 levels rise, symptoms such as fatigue, drowsiness, humidity, and indoor air quality issues occur. The indoor carbon dioxide concentration is visualized at one-second intervals, making it easy to see when ventilation is needed.

How to Select CO2 Sensors to Avoid Failure <Domestic Manufacturers, Japanese Standards>

How to Select CO2 Sensors to Avoid Failure <Domestic Manufacturers, Japanese Standards>

Equipped with NDIR sensors that comply with the Ministry of Economy, Trade and Industry guidelines; simply place the ventilation timing on the table; numerous domestic implementation case studies.

Please download and refer to the document "Selecting CO2 Sensor Models to Avoid Failure" for reference materials. ■ Below is an introduction to the NDIR sensor-equipped "C.H.C Marvel 001." In Japan, there are standards for CO2 concentration in living spaces, and from the perspective of legal compliance and regulations, it is necessary to adjust indoor CO2 levels to not exceed 1000ppm. From the COVID-19 Countermeasures Promotion Office (Cabinet Secretariat): "Points for Preventing COVID-19 Infection" *Excerpt [If possible in restaurants, install CO2 sensors to monitor carbon dioxide concentration and maintain it below 1000ppm through appropriate ventilation.] The first CO2 measuring device in Japan is the "CO2 Sensor/Controller/Monitor." The "CO2 Sensor/Controller" measures indoor CO2 levels and notifies you of CO2 levels to ensure a comfortable and energy-efficient living space. In recent years, the health risks posed by indoor CO2 concentrations in highly airtight buildings have become a growing concern.

High-precision CO2 sensor "eAir" that visualizes "secrecy"

High-precision CO2 sensor "eAir" that visualizes "secrecy"

Visualizing air quality in various locations. Making density visible to create a safe space. A popular CO2 sensor introduced on NHK and TV Asahi news programs.

● Preventing the "three Cs" (closed spaces, crowded places, close-contact settings) in conference rooms and stores to implement infection prevention measures. By accurately measuring and visualizing the CO2 concentration in the space, efficient ventilation can be achieved. It can also measure room temperature and humidity, providing reliable ventilation guidelines and air conditioning management, which is a unique advantage of "eAir." ● No setup required. Ready to use right out of the box. eAir can be used immediately after being taken out of the box without the need for additional devices or settings. The CO2 concentration is clearly displayed with a dual indication of four-color LEDs and real-time numerical values. ● Even more convenient! Check CO2 concentration from a distance with app integration. By linking the app, you can check the CO2 concentration on your iPhone or Android smartphone even when you are not on-site. By monitoring air quality from various locations such as building management centers or while out, you can gain a greater sense of security. High-precision measurement using NDIR technology specialized for CO2 concentration. It allows for more accurate and faster visualization of the three Cs with the CO2 monitor, enabling appropriate actions such as immediate ventilation to be taken.

CO2 Sensor "Logtta"

CO2 Sensor "Logtta"

Visualize ventilation with carbon dioxide (CO2) concentration! By looking at the CO2 concentration, you can understand the state of ventilation.

"Logtta" is a CO2 sensor with a measurement cycle of 1 minute that displays ventilation conditions in numerical and color formats. By adding a temperature and humidity sensor, it is also possible to display temperature and humidity. Humans exhale CO2 through breathing, and in a sealed room, CO2 concentration continues to rise. Good ventilation keeps CO2 levels below a certain threshold. It is used in restaurants, fitness gyms, daycare centers, tutoring schools, and offices. 【Features】 ■ Install a tablet to display ventilation conditions ■ Customers can view ventilation conditions on their own smartphones ■ Understand when ventilation is necessary ■ Anyone can see the ventilation status, allowing those who notice to open windows for ventilation *For more details, please refer to the PDF document or feel free to contact us.
