Particulate Matter sensor Module
Particulate Matter (PM1, PM2.5, PM10, and PM100) Monitoring
Our Particulate Matter sensor module is engineered to accurately measure PM1, PM2.5, PM10, and PM100 concentrations in ambient air, providing real-time data on atmospheric particulate matter levels. The sensor’s advanced support electronics ensure compactness and reliability, making it a robust solution for continuous air quality monitoring.
These sensors work on laser scattering technology with a heated inlet to eliminate moisture and ensure accurate air quality data. The integration of a heavy-duty fan and advanced lasers guarantees precise data and durability, making these sensors ideal for outdoor applications requiring real-time air quality insights.
These advanced particulate matter sensor modules are utilized in our outdoor air quality monitoring systems, such as Polludrone and AQBot. Additionally, these modules are a key component in our specialized ambient dust monitor Dustroid. These versatile sensors are used in a variety of applications, including national air quality monitoring, environmental health impact assessments, construction site monitoring, mining, smart cities, and air quality research projects. By providing real-time particle concentration data, Oizom’s PM sensor modules support a wide array of environmental monitoring needs, ensuring accurate and reliable air quality data for diverse applications.
Our particulate monitoring sensors are calibrated with reference stations, housing BAM-1020 for PM (- β-ray Attenuation) which significantly enhances the data accuracy and reliability of our sensors, ensuring high-quality air quality monitoring results.

The PM sensor module works on the physical principle of laser scattering, also known as optical particle counter (OPC), which measures dust particles illuminated by laser light at a 90° angle. The light scattered from each particle is collected at approximately 90° by a mirror and detected by a photo-diode. After that, the signal is fed into a multi-channel size classifier where a pulse height analyzer classifies each pulse that is proportional to the particle size. Thus, the counts in the channel corresponding to PMs convert to the concentration of PM.
