In this episode, James Heydon, who lives in Sheffield UK, will share with us his professional thoughts on air pollution.
James is an Assistant Professor in Criminology.
You may think, how can a criminologist shed light on air pollution!
Well, James is currently researching air pollution regulations, and his academic studies in human behavior could help us understand better why most people neglect to think about the air they breathe.

Review: Air Quality Guardian by Analox

This is the second Analox product review that I have written on my blog. I like the product range and the solutions that Analox offer to professionals. The first review was about the CO2BUDDY, a portable/wearable carbon dioxide (CO2) monitor. In this review, I will write about the Air Quality Guardian. The Air Quality Guardian is a CO2 monitor station, designed for those that don’t want unnecessary smart features and too many bells and whistles.

The large LCD display provides plenty of clear information for those professionals that don’t have the luxury of time to continually take their phones out of their pockets in order to check the CO2 concentrations and trends. Keep in mind, the monitor measures other environmental parameters as well.


  • 4” backlit LCD screen
  • CO2 Sensor Low drift NDIR (Non dispersive infra-red) CO2  sensor with a long lifespan 
  • Temperature and Relative Humidity Sensor
  • Simple 4 button navigation
  • Built-in data logging 
  • Simple three-level indoor air quality indication system including: 
  • Configurable audible and visual alarms
  • Power and charge via mini USB
  • 8 hour battery backup
  • Wall mountable or desktop
  • Dimensions 120 x 90 x 35 mm 4.75 x 3.5 x 1.4 in

Awair OMNI + Djinn

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: CO2BUDDY by Analox

Carbon dioxide (CO2) monitor sales have skyrocketed during the pandemic because they are good indicators of the indoor conditions in public places like schools, offices, restaurants, etc. The CO2BUDDY can be used in all these cases. However, it can cover even more scenarios as it functions as a tool for professionals that work in places where the conditions are extreme, for example, in dry ice shipping & logistics and COVID-19 vaccine distribution channels.

Dry ice is a solid form of CO2. As it warms, it goes through a process called sublimation, meaning it goes directly from a solid to a gas, bypassing the liquid state. As a result, huge concentrations of CO2 are released into the atmosphere and the environment. These concentrations can reach critical levels for the health of the employees.

I want my review to be as accurate as possible and despite the fact that I don’t work in harsh environments, I know people that they do, so I asked them to wear the CO2BUDDY during their workdays and share their experience with me. They were more than happy to help and they also took some photos. Before reading their experience let’s learn some technical details about the monitor.

Review: Awair OMNI – B2B Air Quality Monitoring Solution

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.
