Abstract The paper presents the research and design of air purifiers based on Negative ion technology. The central device is designed based on the STM32 microcontroller to control the high voltage circuit that generates negative ions up to 6 kV. The sensors measure the concentration of fine dust PM10, PM2.5 integrated in the device to assess the air quality after processing through this device. An interface developed on the Webserver allows to collect and display information about air quality. A filter is integrated by us to prevent fine dust from circulating air through the purifier. Initial results show that the device has worked well, suitable for air purification applications in homes, apartments or hospitals to eliminate air pollution including harmful viruses today. Keywords: Negative ion; flyback; loT; PM2.5; PM10. |
