[Column] What is a CO2 Sensor? Mechanism and Operating Principle

What is a CO2 sensor? Introducing its mechanism and operating principle! / Leave the design of electrical and electronic circuits, and printed circuit boards to Nippo! /

A CO2 sensor is a device used to measure the concentration of carbon dioxide gas. It helps monitor the amount of CO2 gas released into the external environment and contributes to improving energy efficiency and ensuring indoor comfort. The general operating principles of CO2 sensors are mainly of two types: ◆ Chemical Sensor This method obtains gas concentration by utilizing "redox reactions." The electrical characteristics of the sensor (such as resistance and capacitance) change due to CO2 gas, and the concentration of CO2 gas is calculated from this change. ◆ NDIR: Non-Dispersive Infrared Method This method utilizes the characteristic that "molecules absorb infrared light at specific wavelengths." It measures how much light is absorbed and calculates the CO2 gas concentration based on that information. Currently, "NDIR-type CO2 sensors" are mainstream due to their high sensitivity and stability. Within NDIR-type CO2 sensors, there are different principles, including: - Single light source single wavelength method - Dual light source single wavelength method - Single light source dual wavelength method Nippo offers a wide range of services, from the design of electrical and electronic circuits to the design of printed circuit boards.

EnOcean CO₂ Sensor

EnOcean CO₂ Sensor

Efficiently avoid crowding, optimal for ventilation systems.

CO₂ sensor unit that measures temperature, humidity, and carbon dioxide concentration. It complies with the "Guidelines for the Selection of Carbon Dioxide Concentration Measuring Instruments" established by the Ministry of Economy, Trade and Industry. It uses solar cells for power generation and storage as the main power source, and is equipped with a backup battery. The backup battery can be used for about 10 years without replacement. *This is limited to use with a measurement interval of 15 minutes (depending on installation location/use environment). The measurement interval can be selected from 1 minute, 5 minutes, 10 minutes, 15 minutes, or a variable mode based on CO₂ concentration. In variable mode, the measurement interval is automatically adjusted according to the CO₂ concentration. In environments without people, such as at night, the measurement interval is extended, which is expected to reduce power consumption. 【Features】 ■ Data transmission via EnOcean wireless communication ■ Compliance with the guidelines established by the Ministry of Economy, Trade and Industry ■ Main power source is solar cell generation ■ Backup battery lasts about 10 years without replacement ■ Measurement intervals can be selected from 1 minute, 5 minutes, 10 minutes, 15 minutes, or variable mode

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 and adherence to regulations, 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, etc." *Excerpt* [If possible in restaurants and other establishments, 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 to ensure a comfortable and energy-efficient living space and notifies you of the CO2 levels. In recent years, the health risks posed by indoor CO2 concentration in highly airtight buildings have become a growing concern.
