outdoor air quality
What is outdoor air pollution?
Air pollution is an environmental issue and a health risk for humans. Clean air is super important for us, as is clean water. One key component of air pollution is the so-called “particulate matter”. These are very small, microscopic particles that float in the air. The dangerous thing about PM is: you cannot see it (because it is so small) and often, you also cannot even smell it. And this is because of that, that particular matter is sometimes referred to as “the silent killer”. When the aerodynamic diameter of the matter is equal or less than 2.5 microns, we speak of PM2.5. Just so you get an idea how small that actually is: The average cross-section of a human hair is 50 microns. So we could say that PM2.5 is 50 times smaller than one single hair. 1 micron is 0,001 millimeter. So, that is really really small. PM 2.5 can appear in indoor environments as well as outdoor environments.
At SEZO we believe that knowledge is the first step to breathing clean air. That is why we are happy you found this landing page. Enjoy the read!
Why is outdoor air quality so important?
Air pollution constitutes a risk to both the environment and human health. Health studies in the European Union have shown the links between exposure to particulate matter and health risks. Air pollution can lead to illnesses and premature death. The detrimental health effects include cardiovascular effects such as cardiac arrhythmias and heart attacks, as well as respiratory effects like asthma and bronchitis.
But there is good news as well: Now we can measure air pollution and particulate matter. The technological progress in the last 15 years – including the rise of new network technologies, cloud solutions and IoT products – enable us to take the necessary actions. The first step is to make the silent killer “visible”. By measuring outdoor air quality, we can gather the necessary data to make informed decisions and plan measures to counter it.
WHAT AIR POLLUTION PARAMETERS DOES SEZO MEASURE?
SEZO IoT products (Internet of Things) have built-in outdoor air quality sensors that measure air pollution in real time. By air quality we usually refer to PM1, PM 2.5 and PM10. This particulate matter is very small, microscopic and inhalable. We all have encountered PM in our lives already – whether it was in the form of dust, smoke, pollen, soot, dirt, or mold spores. When we measure air pollution we can usually differentiate between organic matter (for example spores), and inorganic matter (for example dust).
By measuring outdoor air quality, SEZO products can help to raise awareness AND facilitate the undertaking of potential countermeasures. Countermeasures can be manyfold: they can be passive, like skipping your morning run (due to high levels of air pollution) or proactive, like identifying the source of the outdoor air pollution and decreasing it (or eliminating it alltogether).
SEZO IoT products can also measure other outdoor environmental paramenters, like temperature, humidity, atmospheric pressure, light intensity and noise level.
What features do we offer?
The features of SEZO outdoor air quality products are diverse: the devices are compact and sturdy. They either run on LoRaWAN or LTE-M technology. We usually work closely with our clients to determine which features and technology would be the best fit – based on the respective use case and lifetime. Also, we are able to tailor the Hardware to the needs of our clients. If you are curious about the SEZO air quality monitoring system, feel free to schedule a consultation call with one of our sales engineers.
The concentrations of PM are primarily responsible for air quality.
Tackling air pollution with LoRaWAN & LTE-M technology
School yards &
outside parking lots
One plausible use case for our SEZO IoT products made for measuring outdoor air pollution are schools and public institutions. Measuring air pollution can make schools a safer place for both children and staff. School management can measure air pollution in order to ensure good air quality both inside and outside of school premises. By measuring particulate matter levels such as PM2.5, school decision makers can make an informed decision, whether it is wise to send kids outside or not. Our SEZO IoT devices can detect harmful pollutants in school yards and parking lots. SEZO products are capable of sending data via LoRaWAN to the Orange Live Objects platform.
Another use case for SEZO solutions is found in industrial manufacturing sites. Our devices are capable of sending data to the Orange Live Objects platform via LoRaWAN and can measure particulate matter (PM1 / PM2.5 / PM10) and sound levels. Some of our SEZO devices have an integrated PIR (infrared) sensor, so they can detect the presence of people (just like light detectors). This can be used as an alarm function, individually configured by the user. PIR sensors are commonly used in security alarms and automatic lighting applications. The alarm threshold level can be individually configured for measured parameters.
FACILITY MANAGEMENT &
Our IoT products can complement facility management and oversight of refineries and chemical production plants by adding an additional layer of security. Facility managers can use our products to measure shocks and movements of critical facility components and machinery. This is accomplished by the built-in accelerometer. It is worthwhile noting that the devices can be adjusted to clients’ individual requirements, involving the measurement of basic environmental parameters, i.e. temperature, humidity, atmospheric pressure and sound levels. Some of our IoT products are capable of sending data to the Orange Live Objects platform via LoRaWAN technology.
