In an office of about 20 square meters, there is no smoking in the room. The instantaneous value of PM2.5 is 75.2 micrograms/cubic meters. To test the effect of the experiment, the staff closed the doors and windows and lit two cigarettes at the same time. At this point, PM2.5 in the office soared to 416.3 micrograms/cubic meters. It took about 20 minutes for PM2.5 to return to 75.2 micrograms/cubic meters after opening doors and windows to exhaust smoke.

Through experiments, PM2.5 is so high in 20-level office, especially in the narrow car space, smoking a cigarette will produce a huge amount of pollutants, which not only contains nicotine, tar, but also carbon monoxide and various irritants, carcinogens. Therefore, it is imperative to install PM2.5 sensors in the car. At present, many PM2.5 sensors and air quality sensors are installed in the car air conditioner or air purifier. When PM2.5 in the air is detected to increase, it will be displayed on the display screen, or voice broadcast, automatically turn on the car air conditioner. Or an air purifier to give the car owner a comfortable driving environment.

The infrared dust particle sensor HPD05 uses the principle of optical scattering to measure the dust concentration within the detection range through the conversion of light path and circuit. High precision dust sensor HPD05 has the characteristics of small volume and high precision, low power consumption, short response time, and stable operation under high dust concentration. This infrared sensor principle PM2.5 detection module can be applied in air purifier, fresh air system, air conditioner with purification function, PM2.5 detector and so on.
