Problems solved by technology
For the concentration correction of the particle sensor, methods such as high-temperature heat tracing and vaporization compensation are used in the prior art, and dehumidification equipment is added inside the particle sensor to reduce the influence of relative humidity on the concentration measurement of the particle sensor. Although the existing methods can be effective Correct the measured concentration of the particle sensor, but its implementation cost is very high, and it is only suitable for industrial-grade particle sensors, not for the concentration correction of laser scattering method particle sensors for civil buildings

Description
technical field [0001] The invention relates to the technical field of particle sensor calibration, in particular to a method for correcting the concentration of a laser scattering particle sensor. Background technique [0002] With the development of the economy, people's demand for a healthy indoor environment continues to grow, and PM2.5, which can enter the lungs in indoor and outdoor air, has gradually become the focus of attention. Relevant research shows that the per capita indoor PM2.5 inhalation is four times that of outdoors. Due to the large specific surface area of PM2.5 particles, viruses, bacteria and other harmful substances are easy to accumulate. When the particulate pollutants that can enter the lungs reach a certain concentration, harmful substances enter the human body through the air, causing lung cancer, Diseases such as respiratory inflammation. [0003] For outdoor air quality, people can obtain relevant information by observing the intensity of s...
