Review: Awair OMNI – B2B Air Quality Monitoring Solution

Sotirios Papathanasiou5 Comments

Awair is one of the earliest companies in the space of IoT air quality monitoring with great experience and knowledge as they have released a few consumers based air quality monitors like Awair Original, Awair 2nd Edition, Awair Element, and Glow C. Recently they entered the enterprise market with the release of Awair Omni.

I have seen the evolution of the company from the beginning as they have designed some of the most iconic domestic air quality monitors. The design language of Awair Omni is exactly what you expect from an air quality monitor inside a business environment like an office. The simplicity and the elegance of the product blend harmoniously without creating unnecessary distractions to the occupants of the room yet with the right information always available thanks to the dot matrix LEDs.

Thailand School sets the AQ bar high – An example to be followed

Sotirios Papathanasiou4 Comments

On Earth, there are over 7 billion people but very few of them have a clear vision of a future and how important air quality is for our health. You will find politicians that are unwilling to enforce air quality laws, you will find educators scared to share with parents the indoor air quality, and you will find lots of people unaware of what they breathe or what they burn.

Among all of them, you will find very few people that want to make things right for the rest. In this case, the Head of School at Prem Tinsulanonda International School in Chiang Mai, Thailand was brave and educated enough to recognize the power of air quality data.

Chiang Mai is a city in exotic Thailand that always ranks in the top polluted cities in the world between March and April. The reason is the burning season. I was taught about the 4 seasons (Spring/Summer/Autumn/Winter) at school but it turns out that they have a fifth season − normally in March and April − when crop waste burning and forest fires fill the air with particles, PM2.5 levels can reach 300 μg/m³.

It is not a coincidence that everywhere you look nowadays you see a small, square, and white monitor with a screen in the middle that displays some numbers! Well, this is Aranet4 which was developed by a Latvian company.

Aranet4 is a small and mighty CO2 monitor that surprise people for two reasons. First of all, it is very comprehensive, and secondly, most people are intrigued by the technology of the display as it uses an e-ink display and, to the untrained eye, looks like a simple sticker.

The commonly found AA batteries can operate the monitor for up to 2 years so you don’t have to worry about them. It uses a single channel non-dispersive infrared (NDIR) sensor technology for accurate CO₂ measurements, read more here.

Specifications

  • Carbon Dioxide (CO2) NDIR
  • Temperature (ºC/ºF)
  • Relative Humidity
  • Atmospheric Pressure
  • e-ink Display
  • Bluetooth
  • Buzzer (Alarm)
  • AA Battery Operated (up to 2 years)

Review: Piera-7100 by Piera Systems

Sotirios Papathanasiou6 Comments

Recently, I shared an illustration that demonstrates, based on scientific research, how deep pollution particles can go into the human body.

Particulate matter (PM) are basically sneaky and invisible (to the naked eye) particles of various sizes that trigger inflammatory responses all over the human body depending on their size/origin and how deep inside us they can go. They are even able to destroy human tissue when the origin of the particles comes from the combustion of fossil fuel or biomass burning.

The smaller they get the easier it is to enter our bloodstream and affect every cell and organ in our body, even our brain. For this reason, it is very important to start monitoring the unregulated ultrafine particles aka nanoparticles or PM0.1 or UFP.

The IPS7100 by Piera Systems (a Canadian company) is a new generation low-cost laser scattering sensor capable of measuring those ultrafine particles PM0.1 but also fine particles PM0.3/PM0.5/PM1/PM2.5 and coarse particles PM5/PM10. In total, the 7100 series offers 7 output bins.

Spring Clean Your Indoor Air Quality

Sotirios Papathanasiou5 Comments

During Spring (March, April, May) most people in Northern Hemisphere dedicate extra time to clean and organize their house for the warmer months. Many times we start this process unconscious of the dangerous chemicals present in cleaning products that may be released into the indoor environment. What can we do to improve indoor air quality, especially during spring when many people suffer from allergies?

Here I will conclude a few tips and steps in order to make the most out of this process and detox your house from nasty chemicals and other pollutants/allergens.

1st Tip – Bed Linen

It is important to ventilated bed linen and in case this is not an option we can always change them with clean ones. It is hard to tell how often someone should change the bedsheets but I would recommend at least 2 twice a month. Avoid synthetic textiles like Acrylic, Polyester, Nylon, etc, and invest in good cotton or silk (expensive) sheets and pillowcases as they offer the most comfortable experience, and they don’t pollute the environment once they are washed.

Dead skin and hair can build up and we don’t want to feed dust mites. According to House Dust Biology by J. Bronswijk human skin particles make up approximately 53% of household dust which leads me to the next tip.

I am very happy to announce that I am launching a new series of Podcast episodes where people from all around the world will be able to share their experience with air pollution and how it affects their lives.

The episodes will be available in all big Podcast distributional channels like Apple Podcast, Google Podcast, Spotify, and Spreaker.

Episode 1 : London, UK – Traffic Pollution and LTNs

In the first episode, we will hear Ediz from London, UK. Ediz is a clean air campaigner and he and his family members have to breathe lots of traffic-related air pollution as his neighborhood is jammed by hundreds of cars every day.

Smoggie-PM + Thank you

Sotirios PapathanasiouLeave a comment

Choosing the 5 volunteers was a very difficult task because I had to take into consideration many factors. I wish I had as many monitors as the people (+150) that emailed me. The finalists are from Belgium, Uganda, Azerbaijan, the USA, and Spain.

The second Call for Volunteers was even more successful than the first one and I had the chance to learn from you a little more about the problems of air pollution around the globe and the situation each one of you faces. From Nepal, Poland, Netherlands, Australia, Azerbaijan, India, Romania, Italy, France, Kenya, Belgium, Greece, Denmark, UK, the USA, Finland, Serbia, Mexico, Spain, Israel, Ireland, and many many other places.

I want to THANK YOU all, it really means a lot your offer to raise awareness on such an important problem. I will follow closely the measurements from all 5 locations in order to understand better the impact air pollution has in the communities.

Remember, you can always purchase the inexpensive Smoggie-PM here.
