Smart Indoor Air Quality Monitoring



“Hypercapnia means buildup of carbon dioxide in your bloodstream. It affects people who have chronic obstructive pulmonary disease (COPD). If you have COPD, you can’t breathe as easily as other people do. Capteurio provides cost effective real time air quality monitoring so that you can easily monitor your surrounding and relax while our sensors do the job”

Researchers have proved that poor indoor air quality have major impact on human health, approx 4 million people die every year due to indoor air pollution and most of the people suffer from various diseases like asthma, respiratory inflammation, decreased lung function, and cancer even low-quality air also reduces human productivity and ability. Indoor air pollution is one of the top 5 environmental public health risks, people are suffered from airborne illnesses, during COVID-19 public safety, people have to stay at home, if there is high attendance of people in the house or indoor social gathering there will be high Co2 concentration which actually leads to the transfer of diseases from one person to other finally result in respiratory problems and other serious illness such as COVID -19.

Capteurio’s Smart Indoor Air Quality devices (CAPTEUR CTH) are the most suitable monitoring device for Indoor locations, it can inform the authorized person about the real-time readings of temperature, humidity & carbon dioxide(Co2) of their assets. CDAP (CAPTEURIO DATA ANALYTIC PLATFORM) gives you a clear view of the indoor air quality of your places where you spend a lot of time.

Air Quality Monitoring plays a vital role for Home, Office spaces, educational institutes, labs, indoor gaming zones, and many more. CAPTEURIO Smart Air Quality Monitoring measures parameters such as C02, Temperature, and Humidity. In our rooms, the main culprit is our body and resources that are releasing harmful gases such as carbon monoxide, Carbon dioxide, Nitrogen, etc. Cooking using a gas or wood stove and fireplaces or any flame in our home releases harmful gases such as carbon monoxide and  Co2. If Co2 is above 5000 ppm for long, it might cause dangerous health conditions and will impact the lifespan of individuals. 


Co2 is one the most abundant gas in the atmosphere. Co2 is harmful for the human body causing health problems such as inflammation, reduced cognitive performance and kidney and bone problems. Some symptoms are directly or indirectly related to Co2 such as dizziness, headache, nausea, rapid breathing, shortness of breath, deeper breathing, increased heart rate (tachycardia), eye and extremity twitching, cardiac arrhythmia, memory disturbances, lack of concentration, visual and hearing disturbances (including photophobia, blurred vision, transient blindness, hearing loss and ringing in the ears), sweating, restlessness, vomiting, shaking, confusion, flushed skin, panic, parathesis (a sensation of numbness in the extremities), disorientation, convulsions, unconsciousness, coma, and death.



Co2 Concentration

Health Effect

350-400 ppm

Fresh air, perfect Condition

400 ppm

Average Outdoor Air Level

<600 ppm

Acceptable condition of indoor air quality in rooms

400-1000 ppm

typical level found in occupied spaces with good air exchange.

City/Urban Areas

1000 ppm

Impairs judgment, decision-making ability, and thinking skills on a short-term basis, even for healthy individuals.

Upper limit of fresh air

1,000–2,000 ppm

complaints of drowsiness and poor air.

2500 ppm

Many individuals are rendered cognitively marginal or dysfunctional.

2500- 5000ppm 

headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.

Poor Ventilation

5,000 ppm with 20.9% Oxygen

Headache, lethargy, mental slowness, emotional irritation, and sleep disruption

6000-8000 ppm

Submarine air

60000 ppm

Hearing and visual disturbances(within 1-2 minutes)

7% (70,000 ppm) with 20.9% Oxygen

Death within 5 min


Air quality plays a vital role in the growth of humans, especially for children. If the quality of air is not good then their efficiency is not good, Children are much more active when they are involved in outdoor activity, reasons are very simple due to fresh air. Many people believe that health can be impacted through outdoor air pollution, but the actual facts are that health mostly affects indoor air quality. The main reasons are that our bodies generate Co2, spending 80-90% of our time indoors with an inadequate circulation of air in the closed room or AC room which gradually has a strong effect on our health.



Mostly, people who are living in closed spaces or rooms face common problems such as headaches due to low ventilation, CAPTEURIO R&D found that closed rooms like the office room, labs, sleeping room or (room with closed windows, with a person) Co2 level generally lies between 1000-2000. If anyone sleeps in a closed room their Co2 level easily reaches after 4 hours up to 1800+, which directly affects their health which causes headaches and other respiratory problems. 


In the Office room, gathering room, where people are working together and the room is closed, the co2 level increases, which directly affects that worker’s drowsiness, poor performance. CAPTERUIO R&D results found that worker efficiency in these rooms are reduced as compared to those who are working in the clean indoor environment or in the field. The same situation applies for students who are studying in the classroom; after 3 hours they feel drowsiness if there is a lack of air circulation.



One of the causes of road accidents is the high level of CO2 inside cars. Most of the time drivers with passengers use AC which causes less fresh air and higher CO2 inside cars. The high level of CO2 inside cars directly affects the driver’s poor concentration/loss of attention.



These are the most common  issues faced by every individual, when they are in classrooms or offices or call centers or in a place where a large number of people occupy a small area of the room or hall. People spend most of their lives in closed environments. If the air quality of these places are not good then surely we feel the above mentioned issues that can cause serious long term illness.
