    Quality comes first and our products are designed to last.

PM-500 is a laser-based particle sensor which uses light scattering method to detect and count particles and calculate PM1.0, PM2.5, PM10 concentration in a given environment. The sensor features an imported processing chip and photosensitive element. Signals are collected and processed by the microprocessor chip and then output in digital format. The sensor is ideal to detect the concentration of different particles precisely in real time.


  • Adopted by a new-advanced laser particle sensor, based on Mie-scattering theory, it measures PM1.0/PM2.5/PM10, and other particles as small as 0.3um, making particle measurement more accurate.
  • High-performance laser module, depth algorithm optimization compensation, airflow constant system, making measurement more stable.
  • It has a long lifetime of up to 30,000 hours accompanied by Industrial-grade components.
  • 12mm ultra-thin in size, embedded interface, convenient and fast integrated installation.
  • Six-sided fully enclosed metal body, proven EMC and EMI performance, strong anti-interface, air inlet or outlet from the side.

For every PM series particle sensor you purchase, in order to ensure the sensitivity and accuracy, we need to temporarily order production, which will prolong the overall logistics process by 5-12 weeks. If you have stringent needs regarding the delivery time, please be careful to purchase PM series particle sensor. Due to the efficiency of production, we have a minimum limit on the quantity of products you purchased, we hope you can understand. If you have other questions, you can email to contact us.
