In these times of outbreak where many folks are performing from home, ensuring clean and fresh air indoors is more important than ever. That’s why at IoT news we’ve accepted to review a sensible home device dedicated to air quality sensing, the Aranet4 portable CO2 monitor.

According to SAF Tehnika1

The manufacturer of the Aranet4, an optimal air quality:

  • Helps to take care of healthiness and immunity to viruses2
  • Improves productivity and performance
  • Provides energy throughout the day

Even without being a scientist, it’s easy to admit that everybody should care about air quality in our living or working spaces, or in the other closed environment where we’ve to spend a while.

Always on CO2 level display

The Aranet4 helps get a way of the air quality we breathe, whether reception or at the office, by measuring CO2 level because of a particular Nondispersive infrared (NDIR) sensor technology. The CO2 measurements are displayed on a low-power e-ink screen with a color-based quality indicator. The device also measures temperature, ratio and air pressure levels. a fanatical smartphone app (iOS and Android) is out there to attach to the Aranet4 and allows the user to configure the device, view the history of knowledge, set sound alarms and adjust the sensor reading frequency.

Getting started with Arnet4 portable CO2 monitor

The setup of the device is sort of straightforward. the sole question we had when beginning the device was whether or not we should always proceed to a (re)calibration of the CO2 sensor. After checking now (complete documentation and video tutorials are available), it appears that the device comes pre-calibrated and if a primary test in outdoors shows a CO2 level on the brink of 420ppm (particles per million), you’re good to travel with no re-calibration required.

As a second step, we installed the app and will easily pair it with the device. The app is user-friendly and it enables quick device configuration and (firmware) update, also because it displays the history of the parameters sensed (CO2, temperature, humidity, and pressure).

Sold 149 Euros (excluding shipping costs) on the dedicated Aranet4 internet site or on Amazon, the Aranet4 gives you a transparent view of the CO2 level in your environment, additionally to measuring temperature, humidity and pressure. Although knowing the CO2 level in your environment is clearly a plus, one could argue that the CO2 concentration isn’t enough to gauge the air quality. Other air pollutants like Nitrous Oxides (NOx), Volatile Organic Compounds (VOCs) or particulate (PM1, PM2.5, PM10) are generally measured when evaluating air quality. SAF Tehnika, the manufacturer of the Aranet4 has chosen to specialize in CO2, considering that it’s the sole air pollutant constantly produced by a person’s being.

SAF Tehnika explains :

Humans exhale CO2, so regardless of how pure the air is during a room, a person’s presence will always alter the standard of the air during a closed environment.
consistent with many studies3, a high CO2 concentration affects our mental abilities and is probably going to poison us.
CO2 is one among the most drivers of global climate change . because the economic activity and therefore the road traffic experience dramatic reduction on a worldwide scale thanks to the present COVID-19 outbreak, air quality levels within the world’s major cities are significantly improving in March and April 2020. This improvement is essentially thanks to the reductions of air pollutants emissions like CO2 (CO2) also as nitrogen oxides (NOx) – and related ozone (O3) formation – and of particulate (PM) from factories and road traffic.

Anyway, whatever air pollutant is sensible for you, one obvious advantage of a tool just like the Aranet4 is that it raises awareness on air quality issues and definitely helps adopt good habits for your indoor environment (like opening your windows as often as possible to renew the air!).

Conclusion

The Aranet4 may be a compact and portable smart environment sensing device which is straightforward to maneuver and to require to anywhere. If you’re not trying to find a classy air quality monitoring station, the Aranet4 will assist you to keep an eye fixed on the air you breathe, wherever you’re. it’ll also presumably assist you to change your daily habits and concentrate on renewing your indoor air several times each day. This alone is clearly an advantage of adopting this easy and fun to use, low power air sensing device, sold at a reasonable price.

Plus:

  • Compact, easy to maneuver and to use
  • Precise CO2 level measurement and display
  • Color-based CO2 concentration “criticality” indicator
  • Smartphone app to look at historical data and set alarms

Minus:

  • Not all air pollutants are measured by the Aranet4
  • Harvard University demonstrated that a heightened CO2 concentration reduces the brain’s cognitive abilities by 50%.
  • These are the core abilities your brain uses to think, read, learn, remember, reason, and pay attention: https://dash.harvard.edu/bitstream/handle/1/27662232/4892924.pdf?sequence=1
