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 numbers and colors. 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 increase. 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 conditions, allowing those who notice to open windows for ventilation *For more details, please refer to the PDF document or feel free to contact us.

COVID-19 Measures CO2 Sensor (Crowd Notification Function)

COVID-19 Measures CO2 Sensor (Crowd Notification Function)

It is a system that visualizes "sealing," "crowding," and "proximity" using a smartphone app.

In response to coronavirus measures that require avoiding the "three Cs" (closed spaces, crowded places, close-contact settings), this system visualizes "closed" using the Connect CO2 sensor and "crowded" and "close contact" using the Connect Cellular, all through a smartphone app. It is a device that enables the timing of ventilation using CO2 sensors in offices and meeting rooms, and measures smartphone users with Connect Cellular to visualize congestion levels. With reliable Japanese-made sensors, it ensures appropriate ventilation during the cold winter months. <Features> - Notifies about congestion and ventilation status - Easy installation with no construction required * No internet installation needed, and no wiring work associated with product installation - Communication fees and app usage fees are included in the initial cost, with no monthly payments required. - Equipped with highly reliable CO2 sensors (5 years of no maintenance) - The dedicated app displays congestion and ventilation status in real-time, with push notifications to alert smartphone users about ventilation timing - Power is also battery-operated (USB type-C), making management easy.

Agricultural CO2 sensor

Agricultural CO2 sensor

CO2 sensor optimal for high temperature and high humidity environments.

This is a CO2 (carbon dioxide gas) sensor that measures the CO2 concentration in agricultural houses and storage warehouses for vegetables and fruits, and outputs an analog signal. It can be used in environments with high temperature, high humidity, and high ammonia concentration. Thanks to the automatic calibration function, tedious calibration is unnecessary for about five years.

[IoT Textbook Series] Technical Overview of NDIR Method CO2 Sensors

[IoT Textbook Series] Technical Overview of NDIR Method CO2 Sensors

Customizable CO2 sensors! We will explain the utilization of "Sensor I/F LSI."

In the context of the COVID-19 pandemic, what are the promising indicators of sensing technology utilizing IoT? Currently, the measurement of CO2 concentration using CO2 sensors is gaining attention. Humans breathe in oxygen and exhale carbon dioxide. In other words, CO2 concentration can be used as an indicator to measure whether people are densely packed together. This document explains the utilization of the "Sensor I/F LSI" currently under development by "Tele-Sentient" in constructing CO2 sensors. [Contents] ■ CO2 sensors as an important indicator for social distancing ■ CO2 sensor technology (NDIR method) ■ Tele-Sentient's Sensor I/F LSI *For more details, please refer to the PDF document or feel free to contact us.

New coronavirus countermeasure ventilation CO2 sensor <Domestic manufacturer, made in Japan standards>

New coronavirus countermeasure ventilation CO2 sensor <Domestic manufacturer, made in Japan 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 available.

In Japan, there are standards for CO2 concentration in living spaces, and from the perspective of legal compliance, it is necessary to adjust the indoor CO2 concentration to not exceed 1000 ppm. 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 1000 ppm through appropriate ventilation] is measurable. The first CO2 measuring device in Japan is the "CO2 Sensor/Controller/Monitor." The "CO2 Sensor/Controller" measures the indoor CO2 concentration and notifies you of the CO2 level to ensure a comfortable and energy-efficient living space. In recent years, the health risks posed by indoor CO2 concentration in highly airtight buildings have become a growing concern.
