When the quality of the air is good and the purifier is not needed, we can't always know it, and it is also a waste of energy, which is not environmentally friendly.In addition, turning the purifier on and off is also an annoying problem. Therefore, we designed a purifier using the Tyndall effect. It is capable of controlling the purifier switch by detecting the amount of dust particles in the air by light, and controlling the amount of illumination of the LED lamp according to the amount of dust on the screen to visualize the dust. Make the design between the dust and the purifier more aesthetic.
