As we know that day by day enhancement rate of technology as per requirement are on the top priority. If we see today’s atmospheric condition due to air pollution then air pollution detection monitoring system becomes preferably required. It may play useful role regarding this issue. It is directly related to human life. Air pollution causes many types of diseases and disorders such as cancer, lupus, allergic reactions, asthma, nasal infection, eye problems etc. It also creates imbalance in atmosphere. To combat this problem of air pollution, we have proposed a system that will detect air pollution and display the status by using LEDs. And buzzer The System is designed using Arduino. This system provides effective solution to save our environment by controlling air pollution.
