摘 要：Air is one of the essential elements of human’s *** earth’s atmosphere is full of air which contains gases such as Nitrogen,Oxygen,Carbon Monoxide and traces of some rare *** quality of the air has been degrading for some decades due to various activities conducted by the human beings that directly or indirectly affect the atmosphere leading to the air *** are different techniques to measure air ***,with the evolution of time the expensive and less efficient analog devices have been replaced by more efficient and less expensive electronics *** this research,MQ135 sensor is used to measure air quality of a particular location.I2C display is used to monitor the ***,with the increasing in number of vehicles,unplanned urbanization and rapid population growth,air pollution has considerably increased in the last decades in various areas of ***,this project‘Air Pollution Monitoring System’was focused on collection of the data specific location of Chandragiri municipality of Kathmandu *** conclusion,analysis of the data is done with the help of origin software which shows that the Arduino device in this device works perfectly for measuring the air *** quality of the selected area is found to be less than 500 PPM which concludes that the air quality of this area is normal.
