I2P air purifier with air quality monitoring device

Air pollution is an addition of harmful substances in the atmosphere, which results in environmental damage. The industrial development and reduction in forests which are two main root cause of air pollution has increased the death rates people dying from diseases like breathing problem and lung cancer. So, to fight against this serious threat to mankind, we decided to standby this society and we made our mind to do something to detect the amount of impurities in the air and considerably reduce the amount of impurity present in the air. In the project, we are detecting impurities using gas sensor. Impure air is input to the gas sensor. The sensor is connected to the Arduino which consist of code which will help us in detecting the amount of impurities in the air. After taking the inputs regarding the amount of impurities from the doctor we have set a limit up to which extent impurities are not harmful. If the limit exceeds then a buzzer sounds along with LCD display which gives us the information that it's time to switch ON the filtering device. After that filtering device gets turned ON and air gets purified. Coming to applications it can be used in the place where there is a need of oil mist collectors, dust collectors, UV air purifiers etc.
