Particle Sensor for Air Purifier

COVID-19 air purifier

COVID-19 has been declared a pandemic by the WHO at the beginning of year 2020. At the moment of writing, there are 38,273,093 individuals had infected and resulted in 1,086,056 deaths worldwide; these numbers are increasing daily. With the outbreak of the pandemic, the demands for air purifier increased rapidly.

How does air purifier help to keep our health form COVID-19 ? As we all know, the most effective way is isolating ourselves at home for there is no vaccine right now. Research showed that COVID-19 virus can survive for 2 hours in the ambient air. Making sure the indoor air keep clean and good ventilation is vital during the isolation time. Air purifier is very helpful to pure the contaminated particle, while the particle may carry the virus. The air purifier can effectively prevent the spread of the virus during the 2 hours.

As a main component for the air purifier, the particle sensor playing an important role.Cubic R&D team did a lot research to develop several types of particle sensor with the patented API (auto particle identification )technology. Among them, the smallest compact model PM2012 grab the most attention. Its thinnest size which can output not only PM10, PM2.5 and PM1.0 at the same time.

Cubic patented API technology is a algorithm enable the sensor to identify the dust source according to particle distribution and then apply the correct density in algorithm in different dust environment. The accuracy be more preciser with API technology. Besides, Cubic designed constant power laser diode and constant speed blower for the PM2012 to overcome the influence of temperature and ensure a higher accuracy.
