Active phase-control air quality sensor

Abstract

Disclosed is an active phase-control air quality sensor which comprises a sensor cavity and a probe. The sensor cavity is manufactured according to existing air quality sensor cavity manufacturing technology and comprises internal reflective surfaces, an analysis processing unit and a data display unit. The probe comprises light source emitting ends and light source receiving ends which are arranged at positions that the light source emitting ends do not face the light source receiving ends directly; the quantity of the light source emitting ends is a natural number larger than or equal to one, and the quantity of the light source receiving ends is a natural number larger than one. Based on the special structural design, particles in different shapes in air can be detected completely, technical effect of accurate detection is achieved, air quality is monitored in time, whether domestic air purifiers are qualified or not can be tested effectively, and the air quality sensor is an economical professional instrument for common customers, is convenient and flexible to operate and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of air quality detection, in particular to an active phase-controlled air quality sensor. Through the design of a special detection head structure, the sensor greatly improves the structure complexity and capital occupation without excessively increasing the structure complexity. Improve the detection accuracy of air quality, and provide people with the most accurate and scientific air quality reference; Background technique [0002] With the gradual improvement of material living standards, people pay more and more attention to their own health. The process of industrial modernization and the extensive use of petroleum energy, while contributing to the improvement of national income, also inevitably bring air pollution. pollution problem; [0003] Haze, as the name suggests, is fog and haze, but there is a big difference between fog and haze. The aerosol system composed of dust, sulfuric acid, nitric acid ...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the deficiencies of the prior art, the present invention provides an active phase-controlled air quality sensor. The sensor uses multiple sets of probes, and through a special detection mode in which the transmitting point and the receiving point are reversely set one by one, it effectively solves the current problem. Among the existing technologies, the accuracy of air quality detection is too low, the service life is short, and it is not suitable for popularization by the public;
