Oizom - Model PM2.5 - (0-999 µg/m3) -Particulate Matter Sensor Module

The advanced support electronics of this air quality sensor makes it compact and reliable. The sensor works on laser scattering technology and it works on active sampling.

The PM2.5 sensor module works on fan-based active sampling and provides particle concentration in near real-time conditions. The advanced lasers and heavy-duty fan ensures accurate data and stable long term output.

The Outdoor air quality monitoring system like Polludrone Lite, Polludrone Smart and Polludrone Pro use this particulate matter sensor module. Therefore, multiple applications like National air quality monitoring, Environmental health impact, Construction monitoring, and air quality research projects use the PM2.5 sensor module.

• Specifications of the PM2.5 sensor module are listed below:
• Measurement Range: 0-999 µg/m3
• Sensor Life: 1 year
• Minimum detection limit: 1 µg/m3
• Working Principle: Laser Scattering
• Measurement Precision: ± (5 ug/m3 + 15 % of reading)

The PM2.5 sensor module works on the physical principle of laser scattering, also known as optical particle counter (OPC), 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 PM1 convert to the concentration of PM2.5.
