PM monitoring focuses on measuring suspended solid particles and liquid droplets in the atmosphere, such as dust, soot, smoke, with an emphasis on PM 2.5 and PM 10 to evaluate the level of air quality. Highly accurate reference stations, portable artificial intelligence sensors with real-time communication capabilities, and IoT-based devices are available to monitor PM concentrations indoors and outdoors. These systems are used to monitor the levels of PM for public health risk assessment, regulatory compliance, and to help manage pollution.
The global trend toward tightening air quality standards and more stringent emissions controls is creating demand for advanced particulate matter monitoring systems. As a result, governments and environmental agencies are increasingly implementing requirements for continuous and reliable PM data in order to ensure compliance, protect public health, and influence urban planning, which provides incentive for investment in monitoring infrastructure and supporting analytics platforms around the world. For instance, in June 2024, EarthSense partnered with Ganeca Environmental Services, to provide its bespoke solutions and services to the Indonesian government and industries to visualize and manage air quality issues.
Growing population and industrialization within emerging markets around the world have led to increasing amounts of airborne particulate matter (and subsequently an increased amount of split carbon). The increase in airborne particulate levels means there will be a requirement for the establishment of dense networks of sensors to monitor the levels of particulate matter in real time, providing local authorities and businesses with the opportunity to respond effectively to the issue, manage sources of pollution and plan sustainable development throughout metropolitan and industrial areas. For instance, in March 2025, Aclima launched mobile labs in 37 to measure fine particulate matter, black carbon, and VOCs to improve local air quality insights.
Advancements in the miniaturization of sensors and the development of semiconductor technologies have enabled the rapid adoption of affordable, low-power particulate matter sensors. These low-cost sensors will enable monitoring capabilities to be expanded into communities, homes and mobile applications and democratize access to air quality data. Using small-scale Air Quality Monitoring will augment the Data we get from Reference-grade Air Quality Monitoring Stations. For example, in September 2025, Sensirion collaborated with Terabee to expand Indoor Air Quality Monitoring to combat air pollution-related illness.

For instance, in December 2025, Aimtron Electronics partnered with Aurassure to launch IoT-based weather and environmental monitoring systems in India.
Artificial intelligence (AI), machine learning (ML) and advanced analytical tools expected to significantly change the way PM is monitored. AI, ML and advanced analytics will enable higher accuracy data analysis, better detection of PM pollution patterns, improved predictive modelling and improved decision making by both policy makers and businesses. Advanced analytics provide better insights into PM levels versus human health, traffic pattern comparisons, and the impact of PM on weather conditions. For instance, in March 2023, Piera Systems Inc. partnered with MACSO Technologies to organize Piera’s state-of-the-art hardware and accurate air quality data with MACSO’s AI/ML software platform to greatly accelerate the development and deployment of new pollutant models.
Growing awareness of the health impacts of fine particulate matter—especially PM2.5—among consumers, employers, and healthcare professionals is boosting monitoring demand. As a result of increased interest in both Indoor and Outdoor Air Quality, we are seeing more Schools, Hospitals, Workplaces and Homes adopting these systems. Community-led initiatives about Air Pollution have also been built around them. For instance, in January 2026, The National Clean Air Programme (NCAP) developed PM2.5 Monitoring to address the Health Issues that get from the massive amounts of Air Pollution present in many parts of India, the NCAP has set a goal of reducing PM2.5 levels by 40% by 2026.
