Problems solved by technology
[0002] The current air quality measurement and control system includes a control panel and an air quality sensing device. The button circuit set on the control panel controls the system on / off and sets system parameters. At the same time, the second main control chip controls the low-speed operation of the fan through the first main control chip, and the first main control chip receives the indoor air pollution status detected by the sensor, and judges the indoor air pollution status according to the set reference value of the indoor air pollution status, In this way, the power of the fan can be controlled, and the electric energy can be saved under the premise of quickly discharging indoor polluting gases; however, the reference value of the existing fan system compared with the air pollution situation is determined, and the reference value of the compared pollution cannot be automatically updated, so the system Low sensitivity for detecting indoor air pollution conditions
[0003] The disadvantages of the existing technology are: the benchmark value for judging pollution cannot be automatically updated, and the system has low sensitivity in detecting indoor air pollution
