Dust is often not that bad but really small particles 2.5\u00b5m and 10\u00b5m in diameter can enter your lungs and cause health problems. This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time. <\/p>\n\n\n\n<p>After that, the sensor will then calculate equivalent particle diameter and the number of particles with different diameters per unit which determines the air quality.  These sensors are normally integrated with a fan to maintain constant airflow across the sensor.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"> Air Quality Detector Modules<\/h3>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/blog.seeedstudio.com\/wp-content\/uploads\/2020\/03\/image-11.png\" alt=\"\" class=\"wp-image-30117\" width=\"291\" height=\"174\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/03\/image-11.png 425w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2020\/03\/image-11-300x180.png 300w\" sizes=\"(max-width: 291px) 100vw, 291px\" \/><figcaption><a href=\"https:\/\/www.seeedstudio.com\/Grove-Air-Quality-Sensor-v1-3-Arduino-Compatible.html\"> Grove &#8211; Air Quality Sensor v1.3 &#8211; Arduino Compatible<\/a><\/figcaption><\/figure><\/div>\n\n\n\n<p>These air quality detector modules are installed with sensor modules that can detect a wide range of Volatile Organic Compounds (VOCs) and are intended for indoor air quality monitoring.

With its stable output, low noise, and ultra-low power consumption, it is suitable for&nbsp;air conditioners,&nbsp;intelligent air purifiers, and other air quality-related&nbsp;IoT&nbsp;projects.<\/p>\n\n\n\n<p>Different from the traditional pumping dust detection sensor, the HM-3301 innovatively uses fan blades to drive air, and the air flowing through the detection chamber is used as a test sample to perform a real-time and continuous test on the dust of different particle sizes in the air.<\/p>\n\n\n\n<p>This module is a perfect choice for dust detectors, intelligent air purifiers, intelligent air conditioners, intelligent ventilation fans, air quality testing, haze meters, environmental monitoring, and relative products and applications.<\/p>\n\n\n\n<p>Here is a video of the sensor in action: <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"PM2.5 monitoring\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/zQj8RRJcZsk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Specifications<\/strong><\/h4>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Operating Voltage<\/strong><\/td><td>3.3V \/ 5V<\/td><\/tr><tr><td><strong>Operating Temperature<\/strong><\/td><td>-10\uff5e60\u2103<\/td><\/tr><tr><td><strong>Operating Humidity<\/strong><\/td><td>10%\uff5e90%RH (non-condensing)<\/td><\/tr><tr><td><strong>Particle Size<\/strong><\/td><td>3 channels&#8211; 2.5\u00b5m, 5\u00b5m, 10\u00b5m<\/td><\/tr><tr><td><strong>Range <\/strong><\/td><td>1~500\u00b5g\/ m<sup>3<\/sup>&nbsp;(Effective range)<br>1000 \u00b5g\/ m<sup>3<\/sup>&nbsp;(Maximum range) <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Particle Sensor 2.5PM and 10PM &#8211; SDS021 <\/strong><\/h3>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/aqicn.org\/air\/images\/sensors\/sds021.png\" alt=\"Image result for sds021 sensor\" width=\"274\" height=\"201\"\/><figcaption>Ref: <a href=\"https:\/\/aqicn.org\/sensor\/sds021\/\">aqicn<\/a><\/figcaption><\/figure><\/div>\n\n\n\n<p>Next up we have the SDS021 sensor.
