1. what is atmospheric sailing?

Atmospheric three-dimensional navigation monitoring vehicle navigation type environmental quality monitoring system is currently widely used, the effect of the bus, taxi mobile atmospheric particulate matter monitoring system, the regional atmospheric particulate matter pollution for mobile dynamic monitoring. With the monitoring of the movement of buses and taxis in the urban area, it can not only understand the pollution situation of the whole region, but also monitor the local pollution, and realize the comprehensive monitoring from macro to micro within the region; at the same time, using advanced big data and cloud platform technology, combined with the atmospheric particulate matter pollution model, the collected data are scientifically predicted according to the law and trend of atmospheric environmental quality change, the main pollution sources causing environmental pollution are accurately traced to provide a scientific basis for pollution control from the source. On this basis, scientifically and reasonably formulate emission reduction indicators for different regions, different types of regions, and streets, and dynamically adjust the haze control plan in combination with changes in meteorological conditions, and take into account economic development while controlling pollution, and realize environmental protection. And economic development go hand in hand, improve the operability of the plan, and finally achieve the monitoring and control of air pollution prevention and control through this plan.

2. the hazards of ozone

Ozone can reach the deep part of the respiratory tract, which has a strong stimulating effect on the respiratory organs and causes the contraction of the respiratory tract. It is more irritating than nitrogen oxides and sulfur dioxide, and it is more than 10 times more toxic to the respiratory system than nitrogen oxides. Ozone has a very low olfactory threshold. When the concentration reaches 0.02 ppm, it can smell the odor. When it reaches 0.1ppm, breathing for 2 hours will reduce vital capacity by 20% to 0.3ppm, which will stimulate nose and brain. When it exceeds 1ppm, the eyes, nose and throat will be dry, with burning sensation and headache. For a longer time, the central nervous system will be hindered and the thinking will be disordered. At 10ppm, easily cause emphysema. In addition, ozone can also hinder the function of blood oxygen transmission, resulting in tissue hypoxia; damage to thyroid function, bone calcification, and also cause potential systemic effects, such as inducing chromosomal aberrations in lymphocytes, damaging the activity of certain enzymes and producing hemolytic reactions. A large number of experimental studies have shown that exposure to ozone concentration of 0.16 mg/m3 in the air environment, 6.6 hours, healthy people will have a significant adverse effects; when it reaches 0.30 mg/m3, it can cause cough. The experiments of Chinese researchers also show that when the ozone concentration reaches 0.10~0.14 mg/m3, the physiological indexes of the human body will have sensitive changes. The World Health Organization believes that for those who are sensitive to exercise, their respiratory system will be significantly damaged when exposed to an air environment with an ozone concentration of 0.20 mg/m3 for 1 to 8 hours. Children with asthma are the most sensitive group. When the ozone concentration exceeds a certain concentration, their health is most affected, and the condition may worsen. The World Health Organization chose an 8-hour average of 0.12 mg/m3 as the newly revised air quality health standard limit in 2000. China's atmospheric standard is 0.1 mg/m3.

How do 3. monitor ozone?

Here, Shenzhen Technology Co., Ltd. recommend an ozone sensor OX-B431, which has the characteristics of fast response, anti-interference, high resolution, good linearity and high sensitivity. The sensor is a four-electrode electrochemical sensor, which is different from the regular three-electrode electrochemical sensor. An auxiliary electrode is added to the OX-B431 to compensate for the zero current, so that the sensor has a more stable zero point and can detect ozone gas at ppb level.

Range: 0-20ppm

Resolution: 15ppb

Sensitivity:-225 ~-75nA/ppm

Overload: 50ppm
