Smart Sensor Devices AB is pleased to share that an article by its Founder and CEO, Axel G. Hammar, has been published in the October 2026 issue of Australia’s IAQ Magazine. The article explores the importance of particulate matter monitoring and how continuous air quality measurements can help create healthier indoor environments.
Titled “The Particles We Live With: Why PM Monitoring Belongs at the Centre of Indoor Air Quality,” the eight-page article discusses the challenges of indoor particulate pollution, the value of monitoring different particle sizes, and the role of accessible sensor technology in understanding indoor air quality.
Understanding the Particles in Indoor Air
Indoor air quality is often associated with ventilation, carbon dioxide, temperature, and humidity. However, particulate matter (PM) is another important factor that deserves attention.
Fine and coarse airborne particles can originate from outdoor pollution or everyday indoor activities such as cooking, cleaning, human movement, and other building operations. Because many of these particles are invisible to the human eye, their presence and changing concentrations can easily go unnoticed.
The article explains the differences between PM1, PM2.5, and PM10, highlighting why monitoring multiple particle sizes provides useful insights into indoor environmental conditions.
Why Continuous Monitoring Matters
Indoor particulate matter concentrations can change throughout the day depending on occupancy, ventilation, outdoor conditions, and activities within a building.
Continuous monitoring helps reveal these variations, identify recurring pollution patterns, and evaluate whether improvements such as better filtration, ventilation adjustments, or changes in daily activities are having the intended effect.
The article also explores the practical applications of PM monitoring in homes, schools, offices, healthcare facilities, and other occupied environments.
Rather than relying on occasional measurements, continuous monitoring provides historical information that can support more informed indoor air quality management.
The Role of HibouAir in Indoor Air Quality Monitoring
The publication also discusses how compact and accessible particulate matter sensors are making indoor air quality monitoring more practical.
Smart Sensor Devices’ HibouAir is highlighted as an example of this technology, offering monitoring of PM1, PM2.5, and PM10 alongside additional environmental parameters such as temperature, humidity, and volatile organic compounds (VOCs).
With compact, plug-and-play monitoring solutions, HibouAir helps users observe indoor environmental conditions and better understand how air quality changes over time.
The article emphasizes that sensor measurements become most valuable when they are used to support informed decisions about ventilation, filtration, source control, and building operation.
