As the most basic part of life, air is attracting more and more attention these years, for example, PM2.5, smog, etc. Keeping an eye on the quality of the air we breathe is becoming quite important.\u003c\/p\u003e\n\u003cp\u003eThis Air Quality Monitor introduced by DFRobot provides you with the measurements of PM10, PM2.5, PM1.0 as well as temperature and humidity.

At the same time, a temperature \u0026amp; humidity integrated sensing chip is embedded in the module for accurately detecting the temperature and humidity.\u003c\/p\u003e\n\u003cp\u003eIn a word, this air quality sensor combines the particle concentration value, temperature, and humidity monitoring functions onto one module, and outputs the relevant data frames via UART. It can be embedded in various instruments and equipment related to air quality monitoring and environmental air improvement to provide timely and accurate environmental parameters.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34036-content2.webp?v=1791328649\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInstallation Precautions \u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe metal shell is connected to the internal power ground, and be careful not to short-circuit with other external board circuit or chassis shell.\u003c\/li\u003e\n\u003cli\u003eThe best installation method is that the plane where the air inlet and the air outlet are located is in close contact with the air holes on the inner wall of the user machine and the outside world. If this is not possible, there should be no block within 2cm of the air outlet. There should be a structure between the air inlet and the air outlet to isolate the airflow, so as to prevent the airflow inside the user machine from directly flowing back to the air inlet from the air outlet.\u003c\/li\u003e\n\u003cli\u003eThe vent opening on the inner wall of the user machine for the air inlet should not be smaller than the size of the air inlet.\u003c\/li\u003e\n\u003cli\u003eWhen applied to purifier products, try to avoid placing the sensor directly in the air duct of the purifier. If it is unavoidable, set up a separate structural space and place the sensor in it to isolate it from the air duct of the purifier.\u003c\/li\u003e\n\u003cli\u003eWhen used with purifiers or fixed detection equipment, the sensor position should be more than 20cm above the ground. Otherwise, the product may be contaminated by large dust particles or even entangled by flocs near the ground, causing the fan to stop rotating.\u003c\/li\u003e\n\u003cli\u003eWhen the sensor is applied to outdoor fixed equipment, pay attention to the protection against sandstorms, rain and snow, and willow catkins.\u003c\/li\u003e\n\u003cli\u003eThe sensor is an integral component, users should not disassemble it, including the metal shielding shell, to avoid irreversible damage.\u003c\/li\u003e\n\u003cli\u003eThe bottom of the sensor is fixed with 2mm self-tapping screws, and the length of the screw into the shell should not be greater than 5mm.\u003c\/li\u003e\n\u003c\/ul\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\u003eBrand-new patented structure, six-sided all-round shielding, stronger anti-interference performance\u003c\/li\u003e\n\u003cli\u003eThe direction of the air inlet and outlet is optional, wider application ranges\u003c\/li\u003e\n\u003cli\u003eReal-time output temperature and humidity data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\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%@\u0026gt;=0.5μm\u003c\/li\u003e\n\u003cli\u003eEffective Range of Particle Mass Concentration (PM2.5 standard value): 0~500μg\/mᶟ\u003c\/li\u003e\n\u003cli\u003eResolution of Particle Mass Concentration: 1μg\/mᶟ\u003c\/li\u003e\n\u003cli\u003eConsistency of Particle Mass Concentration (PM2.5 standard value): ±10%@100~500 μg\/mᶟ, ±10 μg\/mᶟ@0~100 μg\/mᶟ\u003c\/li\u003e\n\u003cli\u003eTemperature Measurement Range: 0~99℃\u003c\/li\u003e\n\u003cli\u003eTemperature Measurement Resolution: 0.1℃\u003c\/li\u003e\n\u003cli\u003eTemperature Measurement Accuracy: ±0.5℃\u003c\/li\u003e\n\u003cli\u003eHumidity Measurement Range: 0~99%\u003c\/li\u003e\n\u003cli\u003eHumidity Measurement Resolution: 0.1%\u003c\/li\u003e\n\u003cli\u003eHumidity Measurement Accuracy: ±2%\u003c\/li\u003e\n\u003cli\u003eSingle Response Time: ＜1s\u003c\/li\u003e\n\u003cli\u003eComprehensive Response Time: ≤10s\u003c\/li\u003e\n\u003cli\u003eDC Supply Voltage: Typ: 5V Min: 4.5V Max: 5.5V\u003c\/li\u003e\n\u003cli\u003eWorking Current: ≤100mA\u003c\/li\u003e\n\u003cli\u003eStandby Current: ≤200mA\u003c\/li\u003e\n\u003cli\u003eData Interface Level: L＜0.8V, H＞2.7V, maximum level voltage 3.3V\u003c\/li\u003e\n\u003cli\u003eWorking Temperature Range: -10~50℃\u003c\/li\u003e\n\u003cli\u003eWorking Humidity Range: 0~99%\u003c\/li\u003e\n\u003cli\u003eStorage Temperature Range: -40~80℃\u003c\/li\u003e\n\u003cli\u003eMean Time Between Failures: ≥3 years\u003c\/li\u003e\n\u003cli\u003eMaximum Size: 50mm*38mm*21mm \/ 1.97*1.50*0.83 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAir Quality Monitor (PM2.5, Temperature \u0026amp; Humidity Sensor) x1\u003c\/li\u003e\n\u003cli\u003e8Pin 150mm Wire x1\u003c\/li\u003e\n\u003cli\u003ePM2.5 Module Adapter 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\/sen0233\/\" 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":67580878094413,"sku":"E34036-001","price":78.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34036-win1_57b5cda6-3c2e-4eac-80c3-d03b31d77a98.jpg?v=1791328728","url":"https:\/\/www.mlab.com.au\/products\/air-quality-monitor-pm-2-5-temperature-humidity-sensor","provider":"MLAB","version":"1.0","type":"link"}
