Recently, the movie "I am not the God of Medicine" is hotly released, which has aroused the attention of the society to anti-cancer drugs. Instead of fighting cancer, we want to prevent cancer at the source. In the latest list of carcinogens published by the International Agency for Research on Cancer (IARC) of the World Health Organization in 2017, there are 116 items in the list of group I carcinogens (with a clear carcinogenic effect), of which air pollution and particulate matter have been regarded as common and major carcinogens.
How to combat air pollution and breathe fresh air has become an urgent issue. Outside, we filter the air by wearing masks; while indoors, we all have questions, is the air we breathe fresh?
The answer is of course not fresh, there are many harmful gases and air pollutants in the indoor living environment, such as formaldehyde, dust, kitchen fumes and so on. In order to solve the problem of indoor air pollution, we have begun to use air purifiers. Air purifiers, also known as "air cleaner", can adsorb, decompose or transform a variety of air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decorative pollution, bacteria, allergens, etc.), and effectively improve the cleanliness of the air. Air purifier in normal working condition, can absorb more than 95% of the dust particles in the air, for the new house just renovated or home with the elderly, pregnant women and children in the family, the air purifier is indispensable health protection. In China, the coverage rate of air purifiers is less than 5%, far less than in Europe, the United States and other developed regions. In recent years, as people's health awareness continues to improve, the air purifier market is also rapidly heating up. Major air purifier manufacturers are vigorously expanding the Chinese air purifier market, the market price will be expected to go down.
The dust sensor independently developed by Audiowell is applied in all kinds of air purifiers to detect the dust concentration in the space. In this sensor, a diagonal arrangement of an infrared light emitting diode (LRED) and opto-electronic transistors detects the reflected light of dust particles in the air, effectively detects very small particles and can differentiate dust fumes from the house by the pulse pattern of the output voltage.
Audiowell's dust sensors have the following advantages:
- Good consistency
- Long life span
- Reliable quality and stable performance by using cyclic testing methods
- Self-developed with technical support
