IOT Based Smart Air Purifier

With the development in the technologies and modern equipment the level of the pollution has increased significantly. Air pollution caused due to the factories and the automobiles contributes a large share in this pollution and also one of the most challenging because the Particulate matters are released directly in to the air. So, this project is based on solving the global problem of air pollution by designing an air purifier that brings the increased level of air pollution to its lowest level. In this air purifier HEPA filters is used to purify the air and to make it smart sensors and IOTs are used. To make this whole process automatic Arduino based microcontroller (Node MCU ESP12e) is used which makes this whole system self-operating .This model will also use air quality sensor (MQ135 ),temperature sensor (DHT11) and humidity sensor (DHT11) for its working. Along-with this for energy requirements solar panels are used but for future scope electricity generation using piezo-electric plates has also been suggested.
