In recent years, the air purifier market continues to rise in China, and there are many new products in the air purifier market.First, high cost performance plus feelings, so many just entered the bureau of Internet companies tasted the benefits.Second, big data and cloud computing give big companies an edge in intelligence.When it comes to the main intelligent function of air purifiers, PM2.5 sensors are definitely indispensable.
It can be said that the addition of dust sensors, air purifier products more intelligent.At present, general air purifiers are almost equipped with dust sensors.Currently, dust sensor detection methods can be divided into infrared sensor detection and laser sensor detection.Infrared sensors often measure a numerical range, rather than accurate data, which can only be simulated by algorithms.
The laser sensor USES the principle of laser scattering. It scans the air passing through at a uniform speed through the laser, and identifies the diameter of particles in the air according to the changes of current and voltage, etc. fed back by the laser. Then, it converts the number of concentration of particles into weight through precise algorithm, taking temperature, humidity and other factors into account. The measurements are accurate, but the price is also relatively high.
Application fields of luftmy laser PM2.5 dust sensor: air purifier, air conditioner with purification function, PM2.5 detector, range hood, smoke alarm, fresh air system, dedicated PM2.5 sensor, air detector, wearable equipment, etc.
