Road Trip 3799 km – Where will I find the cleanest air?

July 17, 2021September 8, 2021 Sotirios Papathanasiou3 Comments

On 1st August 2021, I will attempt to travel from Spain to Greece in a hybrid car. I aim to reach my parent’s home (yes, I miss them a lot, damn you covid19) and then return to Spain by sea on a ferry.

It is a month-long road trip of about 3799 km (2360 miles) and I hope I will have the chance to meet new places and during this process, I will document the air quality/pollution in different countries/cities in my effort to raise awareness. I will carry with me a portable air quality monitor that measures, particulate matter (PM1.0/PM2.5), volatile organic compounds (VOC), temperature, and humidity. The monitor is the Atmotube Pro which I have already reviewed here and it correlates very well against reference monitors. Personal and 3rd party field evaluations reveal that the monitor correlates very strongly against GRIMM data PM1.0 r2 ~ 0.93, and PM2.5 r2 ~ 0.89 (1-hr mean). PM2.5 data against a FEM BAM correlate strongly as well r2 ~ 0.78.

I feel confident about the data that I will obtain and as the device saves everything on internal storage and in the phone with GPS coordinates, I won’t lose anything and I will be able to answer some questions, like which counties are more Air Quality friendly based on my data, what was my average exposure to PM during the trip in total and in different countries, or if I had stayed at home, would I have been exposed to less PM, etc. Let’s find the Mediterranean country/city with the cleanest air.

I will visit some cities in Spain, France, Monaco, Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Albania, and Greece.

Stay tuned on social media like Twitter and Instagram, as I will post very frequently photos of the trip with AQ data and comments!

Wish me good luck and if you are interested in learning about the air quality in one of the places I will visit or you have any questions please write below.

Awair OMNI + Djinn

May 18, 2021May 18, 2021 Sotirios PapathanasiouLeave a comment

I love combining technologies and services because this is a great and inexpensive way for companies to expand their businesses and for users to have a better experience. Awair has developed a great B2B air quality monitor the OMNI (hardware) and Djinn has developed a great B2B service (software) that combined together may offer better AQ insights or in other words, they contextualize data.

So I took the liberty to use the API Awair provides to its users and integrate it into Djinn’s platform. The reason is simple, Awair measures a plethora of parameters (temperature, humidity, PM2.5, VOC, CO2, noise, and light), and Djinn provides better insights into the impact those various indoor environmental parameters have on our health, like cardiovascular health risk and allergy risk. However, they also provide the productivity index which estimates the quality of the indoor environment with regard to the influence on productivity.

In real-life situations (offices, classrooms, etc) low-quality indoor environments may result in productivity drop up to 10% and more. Often in such cases, indoor environment quality is not comprehended by a person during the work process. The productivity index is based on research by cognitive scientists from various Universities.

According to the researchers, Human Decision Making Performance may be divided into different cognitive functions. Djinn service is able not only to estimate a general level of productivity, called Integral Productivity Index (IPI) but specify it for 9 cognitive activity areas based on research. An IPI is calculated as the average of all 9 directions. Those different models allow you to tune indoor parameters for optimal productivity according to your needs.

Review: Awair OMNI – B2B Air Quality Monitoring Solution

April 29, 2021May 3, 2021 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.

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.

Review: Piera-7100 by Piera Systems

April 13, 2021December 21, 2021 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.

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.

Review: XT Mini by Ethera Labs

March 29, 2021April 6, 2021 Sotirios Papathanasiou1 Comment

Managing air quality monitors (AQM) in buildings is not always an easy task especially if you have deployed a lot of them. When there are many rooms that you have to take into consideration it can become very costly, very fast to equip all those rooms. Is there a way to monitor rooms without an AQM?

Well, it turns out there is a way to monitor the environmental and air quality conditions in rooms that do not have physical monitors nowadays. How?

Ethera Labs, which is a French company, with over 10 years of experience in professional IAQ solutions has integrated powerful Machine Learning (ML) algorithms that predict the conditions in rooms where air quality monitors are not installed, yes that’s right, you have read correctly. They have trained special neural networks by taking a lot of parameters into consideration in order to predict accurately the conditions and alerts users in case they need to take actions or even address an AQ/Environmental incident automatically.

By connecting the station to BMS, they manage to achieve energy efficiency while directly managing the ventilation system, as well as portable air purifiers or giving building operator the right information in advance so they can take action at the right time. They achieve two goals, great air quality and energy efficiency.

Hardware-wise Ethera Labs offers an arrange of monitors that can address different building specifications and needs. In this article, I will review the Mini XT Basic (MX-KIT020) and the NEMo Cloud/Supervision Cloud platforms.

uRADMonitor SMOGGIE-PM | Call for Volunteers Take 2 [Ended]

March 15, 2021March 27, 2021 Sotirios Papathanasiou14 Comments

Back in 2019 uRADMonitor and I organized a “Call for Volunteers” where we gave away 10 monitors all around the world.

Once more we are looking for five volunteers who want to receive a Smoggie-PM monitor. The new version comes with new transparent icy look case and visual indication of the pollution concentration thanks to the LED light.

Volunteers all around the world who are willing to install an Air Quality Monitor in their backyard or balcony or window or any other outdoor environment in order to build a better air quality network and to help you raise awareness in your neighborhood/community.

The only requirement from your side is to have a good Wi-Fi internet connection 24/7 and keep the device on constantly in order to broadcast the measurements to an open map. The WiFi signal must reach the monitor outdoors.

Just email or tweet or DM me on any social media platform, tell me where are you planning to install the monitor and why should I choose you.

What is SMOGGIE-PM?

Smoggie-PM is an ultra low-cost high performance Air Quality Monitor, with Wi-Fi connectivity and a laser scattering sensor (Plantower PMS5003) that measures Particulate Matter PM1, PM2.5 and PM10 and makes it available on your phone or laptop in real time. Also, it is equipped with a Temperature/Humidity/Pressure sensor (Bosch BME280).

Smoggie is an automated, fixed, Air Quality monitoring station. It has WiFi connectivity to send the air quality measurements to the uRADMonitor Cloud in real time. It needs 5V to run, powered by a standard micro-USB cable (the same your smartphone uses in order to charge it). The new versions have a color LED light that reflect the pollution levels in real-time.

Let’s talk: IoT Wireless Network Protocols for Air Quality Monitors

March 8, 2021March 15, 2021 Sotirios Papathanasiou4 Comments

The Internet of Things (IoT) describes the network of electronic devices (air quality monitors, purifiers, motion detectors, cameras, etc.) that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices over the Internet.

In this article, I am going to describe some of the available networks and physical layers that are used by Air Quality Monitors (AQM), mainly for consumer-based products, and discuss which technologies make more sense in 2021+ for Smart Homes/Buildings and Businesses.

Wi-Fi IEEE 802.11

IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) protocols and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) Wi-Fi computer communication in various frequencies including 2.4 GHz, 5 GHz, and 6GHz.

IEEE 802.11a/b/g/n

This standard wireless network protocol is among the most common protocols for communication between the devices and the internet/cloud. Most devices even today use the ~20 years old 802.11b or 802.11g with a linkrate between 1 to 54 Mbit/s and a frequency of 2.4 GHz for power conservation reasons and good wall penetration. The 802.11n transmits the highest data throughput, but at the cost of high-power consumption at 5GHz.

IoT AQMs do not need a high-speed data throughput because the information they transfer is very little and in the range of a few kilobytes. So protocols like the IEEE 802.11ac and IEEE 802.11ax don’t make a lot of sense because they demand energy and they don’t offer good wall penetration in order to cover an entry house/apartment.

IEEE 802.11ax aka WiFi 6 or 6e

There are some claims that IoT devices will adopt the new WiFi 6e (e stands for enhanced) but I don’t think we will see that happening as bandwidth isn’t relevant for AQMs but the range is more essential and the WiFi 6e is designed to cover approximately 30m/98ft indoors. The 6e operates at 6Ghz, as a result, the highest the frequency the shortest the distance a signal can travel within walls. A positive feature of this protocol is that it supports a Low Power Indoor (LPI) mode. In the multi-user scenario, the WiFi 6 module consumes only one-third of that of the Wi-Fi 4 (802.11n) module and they achieve that by shortening wake-up time.

Review: HA500 Air Purifier by Healthy Air Technology

March 4, 2021March 15, 2021 Sotirios Papathanasiou13 Comments

It is not always an easy task to keep indoor air free from pollutants, especially, when Nitrogen Dioxide (NO2) is present in indoor environments. In most cases, there is little you can do to eliminate NO2 and other gases like Sulphur Dioxide (SO2), Formaldehyde (TVOC), or even pathogens like H1N1 Influenza A virus (pandemic flu), and Staphylococcus aureus (or similar bacteria).

Here comes the HA500 Air Purifier by Healthy Air Technology which is able to eliminate all of these pollutants/pathogens from indoor environments. It does that thanks to the triple-layered system with a primary filter, HEPA 13 filter, and Pollution Eraser DNO filter. DNO means D-Orbital Nano Oxide which is made of two parts.

1^st part: The Carrier – Activated charcoal. The material that is used in military gas masks, and captures pollutants within the pores of the charcoal.
2^nd part: The Transition metal oxides – Transition metal oxides are coated in the activated charcoal to form catalysts, and these catalysts break down pollutants and toxic gases into harmless chemicals and then release these harmless materials back into the atmosphere like water, oxygen, carbon dioxide, etc. The DNO is invented by the founding CTO of Oxford Catalyst plc (a leader in novel industrial catalysts).
