And we provide you with relevant sample codes to help you quickly build up air quality monitoring projects.\u003c\/p\u003e\n\u003cp\u003eBased on the principle of laser scattering, the PM2.5 air quality sensor employs a digital universal particle sensor that can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume, which is particle concentration distribution, and then convert to concentration and output via I2C interface.\u003c\/p\u003e\n\u003cp\u003eThe sensor can be embedded in various instruments and meters or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.\u003c\/p\u003e\n\u003cp\u003eIt is typically suitable for smoking rooms, kitchens, hot springs, bathrooms and other environments.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34023-content1.webp?v=1791323839\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow does the sensor work? \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThis sensor adopts the principle of laser scattering, that is, to make the laser irradiate the suspended particles in the air to produce scattering, and at the same time collect the scattered light at a certain angle, and obtain the curve of the intensity of the scattered light with time. Furthermore, the microprocessor, based on the MIE theory algorithm, obtains the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34023-content2.webp?v=1791323854\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLaser scattering principle, accurate measurement\u003c\/li\u003e\n\u003cli\u003eZero false alarm rate\u003c\/li\u003e\n\u003cli\u003eReal-time response and support continuous acquisition\u003c\/li\u003e\n\u003cli\u003eMinimum recognizable particle size 0.3µm\u003c\/li\u003e\n\u003cli\u003eSix-sided all-round shielding, stronger anti-interference\u003c\/li\u003e\n\u003cli\u003eUltra-thin design, only 12mm, suitable for portable devices\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34023-content3.webp?v=1791323874\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEnvironmental improvement equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWorking Voltage: 3.3V~5V\u003c\/li\u003e\n\u003cli\u003eMaximum Working Current: 100mA\u003c\/li\u003e\n\u003cli\u003eStandby Current: ≤2mA\u003c\/li\u003e\n\u003cli\u003eData Interface Level: L＜0.8V, H\u0026gt;2.7V, maximum voltage level 3.3V\u003c\/li\u003e\n\u003cli\u003eParticle Measurement Range: 0.3 ~ 1.0μm; 1.0 ~ 2.5μm; 2.5 ~ 10μm\u003c\/li\u003e\n\u003cli\u003eParticle Counting Efficiency: 50% @ 0.3μm 98% @ ≥0.5μm\u003c\/li\u003e\n\u003cli\u003eEffective Range of Particle Mass Concentration (PM2.5 standard value): 0~500ug\/m³\u003c\/li\u003e\n\u003cli\u003eMaximum Range of Particle Mass Concentration (PM2.5 standard value): ≥1000ug\/m³\u003c\/li\u003e\n\u003cli\u003eResolution of Particle Mass Concentration: 1ug\/m³\u003c\/li\u003e\n\u003cli\u003eConsistency of Particle Mass Concentration (PM2.5 standard value): 1. ± 10% @100 ~ 500 ug\/m³; 2. ±10 ug\/m³@0 ~ 100 ug\/m³\u003c\/li\u003e\n\u003cli\u003eStandard Volume: 0.1 L\u003c\/li\u003e\n\u003cli\u003eSingle Response Time: ＜1s\u003c\/li\u003e\n\u003cli\u003eComprehensive Response Time: ≤10s\u003c\/li\u003e\n\u003cli\u003eWorking Temperature Range: -10~+60℃\u003c\/li\u003e\n\u003cli\u003eWorking Humidity Range: 0~95%% (non-condensing)\u003c\/li\u003e\n\u003cli\u003eMean Time Between Failures: ≥5 years\u003c\/li\u003e\n\u003cli\u003eProduct Size: 72mm * 40mm * 14mm \/ 2.83 * 1.57 * 0.55 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGravity: PM2.5 Air Quality Sensor x1\u003c\/li\u003e\n\u003cli\u003eGravity-4P I2C\/UART Sensor Cable x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0460\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67580629942349,"sku":"E34023-001","price":87.31,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34023-win1.jpg?v=1791323909","url":"https:\/\/www.mlab.com.au\/products\/gravity-pm2-5-air-quality-sensor","provider":"MLAB","version":"1.0","type":"link"}
