With the development of cities, people's living standard is getting higher and higher, and the air pollution caused by the increase of industrial production and vehicle also comes, among which PM2.5 dust concentration is the main cause of air pollution.In order to strengthen prevention and control, many indoor places will use air purifiers to purify the air, and the pm2.5 sensor module is an indispensable component, which is used to detect the current pm2.5 concentration and feedback on the air purifier.
In the market, the demand for air purifiers, fresh air systems and other electrical appliances increases, so does the demand for pm2.5 dust sensors. There are more and more manufacturers of pm2.5 sensors, resulting in uneven quality.What pm2.5 sensor module is good?What are the cost-effective PM2.5 sensors?
According to different detection principles, PM2.5 sensor modules can be divided into laser PM2.5 sensor and infrared PM2.5 sensor. What PM2.5 sensor module is good?If the product requires the output of high-precision dust concentration value, then lefmax recommends the laser series pm2.5 sensor module, whose detection diameter of particles ranges from 0.1 to 10 m. It adopts the mi-mie spherical particle scattering principle to achieve accurate measurement. It has a wide range of application, no need for wind tunnel design, and is compatible with multi-protocol output.
What are the cost effective PM2.5 sensors?Leftmann recommended the infrared pm2.5 sensor module, which USES the principle of optical scattering to obtain the particle concentration.The advantages of the infrared pm2.5 sensor are strong ash resistance, small size, can detect large particles of dust such as pollen, low price, is a low-cost alternative to the laser series of pm2.5 sensor.
These two kinds of dust sensors have their own advantages and disadvantages in terms of price and performance, which can be selected according to the functional requirements of the product.
