I believe that we all know that smoking is harmful to health, is an important cause of cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease, and is also harmful to the respiratory tract and lungs.The smog produced during smoking, namely PM2.5 particulate matter, is even more harmful to human health than the specific gravity of haze.
PM2.5 refers to particulate matter with a diameter of 2.5 microns or less in ambient air.PM2.5 has small particle size, large area, strong activity, easy to attach toxic substances, and can stay in the atmosphere for a long time. Long-term exposure to the environment with high PM2.5 content may lead to airway obstruction or inflammation, affect fetal development and lead to defects.
There have been experiments on PM2.5 generated by smoking in confined Spaces: in a room of about 20 square meters, the PM2.5 content was 75.2 g/m3 when no one was smoking.After closing doors and Windows and lighting two cigarettes at the same time, PM2.5 levels soared to 416.3 g/m3.It took about 20 minutes for PM2.5 levels to recover to 75.2 g/m3 after doors and Windows were opened to vent the smoke.
It can be seen from the experiment that PM2.5 is so high in a 20-square room, not to mention in a small space, such as elevator, car, etc. Smoking will produce a lot of PM2.5 pollutants.Therefore, in order to create a good driving environment in the car, PM2.5 sensors can be installed in the car. Once the PM2.5 sensor in the car detects the increase of PM2.5 content, the system will automatically turn on the car air conditioner or air purifier, giving the car owner a comfortable driving environment.
LUFTMY LD16 laser particle sensor PM2.5 sensor is using the scattering principle to test the dust particles in the air of the small module, has small volume, high precision, good repeatability, consistency, real-time response can be continuous acquisition, strong anti-jamming capability, USES the ultra-quiet fan, sensor testing and calibration, 100% is suitable for use in the airtight environment detection of PM2.5.
