Indoor Air Quality Monitoring

We provide a real-time Indoor Air Quality (IAQ) monitoring service via our bespoke platform.

See below screenshot example of our API platform.


What we monitor

  • CO2 – Carbon Dioxide
  • Temperature
  • Humidity
  • Pressure
  • PM1 – Particles less than 1μm
  • PM2.5 – Particles less than 2.5μm
  • PM10 – Particles less than 10μm
  • VOC – Volatile Organic Compounds


Air quality is one of the most important and most overlooked aspects of a healthy space. Senseteq has a passion for air quality and provides a real-time Indoor Air Quality (IAQ) monitoring service via our platform. We are all encouraged to eat clean & exercise regularly, rightly so. However, we rarely think about the air that we are breathing in all day, every day.  That’s exactly where Senseteq comes in…

Using the Senseteq platform, you have the ability to monitor the air quality remotely, giving you access to review the data over a period to monitor the air that’s within your building.  Not only this, you will receive alerts for when the air quality is poor, to remind you to act, increasing your awareness.

Healthier, Happier,  Increased Productivity, and most importantly AWARENESS.


More about these

  • Carbon Dioxide

Effects of Carbon Dioxide (CO2)

Many people live with high carbon dioxide levels in their homes, cars, and offices without ever knowing it. However, recent studies show that common indoor carbon dioxide exposure can reduce cognitive and decision-making performance up to 50%. The Earth’s atmosphere is about 400 parts per million or ppm (0.04) carbon dioxide. Scientists estimate that before human industrial activity, Carbon Dioxide concentration was around 270 ppmv (part per million by volume). This means that CO2 levels in our atmosphere have risen about 40% since the onset of industrialization.

When we breathe out, the air is 100 times more concentrated in carbon dioxide, around 40,000 ppm (4.0). As you might guess, this can become problematic when you are sleeping or working in a room without adequate ventilation.

At room temperature and atmospheric pressure CO2 is a colourless and odourless gas and, because of this, people are unable to see it or smell it at elevated concentrations. CO2 is not flammable and will not support combustion.  As the concentration of CO2 in air rises it can cause headaches, dizziness, confusion and loss of consciousness. Since CO2 is heavier than air, fatalities from asphyxiation have occurred when, at extremely high concentrations, it has entered confined spaces such as tanks, sumps or cellars and displaced oxygen.


  • Temperature & Relative Humidity

Temperature and humidity are closely linked. Relative humidity refers to the ratio of the amount of moisture present in the air and the maximum amount it can hold. If the weather is cold, the relative humidity may drop low. If the weather forecast of the day states that the relative humidity can reach 100%, it means that the area is most likely to experience rain.

No matter what time of year it is or what indoor and outdoor temperature is, your humidity levels should stay between 30 to 50 percent. If your indoor humidity levels are low or less than 30 percent, it’ll get too dry in your home, and this is called dry air. When this occurs, dry air results in dry skin, nosebleeds, and sore throats. At most times, dry air will make you feel warm, rather than cold.


  • Atmospheric pressure

How does atmospheric pressure affect humans?

As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die.

In addition to cold weather, blood pressure may also be affected by a sudden change in weather patterns, such as a weather front or a storm. Your body, and blood vessels, may react to abrupt changes in humidity, atmospheric pressure, cloud cover or wind in much the same way it reacts to cold.


  • VOCs

Volatile organic compounds (VOCs) are compounds that easily become vapours or gases. VOCs are released from burning fuel such as gasoline, wood, coal, or natural gas. They are also released from many consumer products such as; cigarettes and solvents. VOCs are a group of carbon-based chemicals which evaporate easily at room temperature. We use thousands of these chemicals in products we have around the home, and while some of them have an odour, others have no smell. Some are also created biologically by plants, including some moulds found around the home.

Some of the most common VOCs include benzene, acetone, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene, xylene, and 1,3-butadiene. These can be found in paints, solvents, upholstery fabrics, carpets and adhesives, varnishes, vinyl floors, cleaning chemicals, air fresheners and cosmetics. At any one time, there could be from 50 to hundreds of individual VOCs in the air.

If you have asthma or another respiratory condition, young children, or an elderly person in the house, you should find out about Volatile Organic Compounds (VOCs). These are the groups of people who are potentially susceptible to the effects of VOCs. As with other pollutants, the extent and nature of the health effect will depend on many factors including level of exposure and length of time exposed.

The IAQ Monitor measures VOCs to an index that determines the intensity, duration and frequency of VOCs.


  • Particulate Matters

Why measure PM?

Particulate matter (PM) is everything in the air that is not a gas and therefore consists of a huge variety of chemical compounds and materials, some of which can be toxic. Due to the small size of many of the particles that form PM some of these toxins may enter the bloodstream and be transported around the body, lodging in the heart, brain and other organs. Therefore, exposure to PM can result in serious impacts to health, especially in vulnerable groups of people such as the young, elderly, and those with respiratory problems.

As a result, particulates are classified according to size. The IAQ Monitor focuses on measuring the fractions of PM where particles are 10 micrometres in diameter (PM10) and less than 2.5 micrometres in diameter (PM2.5) and is measured in micrograms (one millionth of a gram) per cubic meter of air or µg/m3.

Some Examples include:

  • Dust, Ash and Sea Spray.
  • Combustion particles – Boilers for heating/ Liquid fuel vehicles.
  • Bacteria, Viruses and airborne viral particles.
  • Pollen, or any other organic particle.
  • Mold spores or smoke.
