  • Abstract:
  • Air Pollution has become a major crisis in today’s world. Making it harder for infants, elderlies and weak immune to live. The adverse effect cause by the prolong exposure to this polluted air leads to increase in the rate thyroid disease, lungs cancer and respiratory illness, along with the decrease rate of the average lifespan by up to 12 years of these people. The increased need of being able to breathe clean air in the environment. This air purifier having AQI detection and automatic turn on and off feature according to the AQI level. The MQ-2 and MQ-3 sensor used to detect smoke (CO2 (Carbon dioxide), NO2(nitrogen dioxide)), (carbon monoxide) CO and Benzene(C6H6), methane (CH4) respectively. The ESP32 microcontroller is used to collect real-time AQI data and transmit it to filter control website. This creates a sense of knowing about the overall picture of the air quality and it effect on health. This IoT-based system can be used for the application in homes, offices, hospital, industrial spaces improving indoor air quality while ensuring efficient energy usage
