Indoor air quality monitoring
Providing a safe and comfortable space using air quality sensor
Gas Sensing Solution
Now that the infection of COVID-19 is spreading all over the world, the importance of ventilation is being advocated.
Asahi Kasei Microdevices (AKM)'s air quality sensors monitor the carbon dioxide concentration, temperature, and humidity of spaces such as rooms, classrooms, and offices to visualize the air.
"Ventilation" is very important for anti-COVID-19 measures
The places where coronavirus outbreaks were confirmed are common in that "a closed space with poor ventilation" and "many people were crowded". According to the opinion of the Expert Meeting on Countermeasures against New Coronavirus Infections (announced on March 9 and 19, 2nd year of Reiwa), as a workaround for situations with a high risk of cluster infection.
(1) Enforce ventilation:
Perform proper operation and inspection of ventilation equipment so as not to create a closed space with poor ventilation. Ventilate to take in outside air on a regular basis.
(2) Decrease the density of people:
Create an environment that does not crowd people
"Ventilation" is an important keyword in anti-COVID-19 countermeasures.

Ventilation issues in anti-COVID-19 measures
The air is invisible to the eye. We don't know when to ventilate or if it is well ventilated. By opening the windows and ventilating, the air conditioner will operate excessively and energy saving will be lost. Therefore, it is required to implement optimum ventilation and realize a "comfortable and safe environment".
The Ministry of Health is said that if it complies with the air environment adjustment standards of the Building Management Law , it will meet the required ventilation volume (30 m3 per person per hour) and will not fall into "poorly ventilated space".

AKM's air quality sensor can measure carbon dioxide concentration and temperature / humidity.
AKM's air quality sensor achieves "visualization of ventilation timing" & "visualization of ventilation status"
AKM's air quality sensor can accurately measure the concentration of carbon dioxide in the room. By monitoring the carbon dioxide concentration and temperature / humidity, there are the following merits.
(1) Visualization of ventilation timing
If a person is in a closed space without ventilation, the carbon dioxide concentration will inevitably increase. Therefore, by monitoring the carbon dioxide concentration in real time and ventilating at the right time, it is possible to avoid the three Cs environment.
(2) Visualization of ventilation status
If we open the windows and replace the air in the room, you can avoid the three Cs environment, but you do not know how much ventilation is being performed. Therefore, optimum ventilation can be performed by monitoring the carbon dioxide concentration and temperature / humidity. AKM's air quality sensor "Aercast" measures carbon dioxide, temperature and humidity and displays the air condition.
Advantages of AKM air quality sensors
AKM's air quality sensor has the following four advantages because it applies its unique compound semiconductor technology and optical path design technology.
(1) Accurate sensing of carbon dioxide concentration and measurement of temperature and humidity
AKM's unique optical path design technology enables accurate measurement of carbon dioxide concentration.
(2) Battery-powered, no power supply required, long life
It is battery-powered with AKM's ultra-low power consumption technology. It can be used for about 2 years without replacing the battery.
(3) Free installation location
It is battery-powered and does not need to be plugged into an outlet, so it can be installed anywhere you like.
(4) It looks small and stylish
The sensor device is small (148 mm x 58 mm x 29 mm) and does not have a power cord, so it is very simple and does not spoil the sight of the interior.
