Want to distinguish between good and bad gym environment, can be reflected from the perspective of air quality. Using the gym environment monitoring system can comprehensively monitor the air pollution, smoking, ventilation and other hidden dangers in indoor decoration for a long time, and solve the problems in time. On the other hand, we can also deal with some unexpected situations, such as avoiding some outdoor fitness programs, reducing the practice of window ventilation and reducing the exercise of indoor bodybuilders in an air pollution environment when outdoor smog is rampant. In this case, the fresh air system or air purifier can be turned on, and the control effect can be verified by the air quality monitoring system. This governance will enable bodybuilders to simply check whether they are in a healthy breathing environment through the big screen or mobile APP, and improve the professionalism of the gym from the side.
