Every chemical based industry has its own emission of gases, but the main problem occurs when the emission is beyond the standardized limit. The reason for crossing the standardized limit is uncontrollable chain reaction of chemicals. The emission of gases through industries cannot be completely avoided, but can be controlled. In our system, we consider designing the protocol using sensors connected to microcontroller based system. The main objective is to study the available feasibility in the air pollution control and provide in the format suitable for microcontroller. The first step in a analysis is to identify all available options to control the pollution(air). Available options are those air pollution control techniques with a potential for application to the emission unit and the pollutant under evaluation. Our system is based on monitoring and controlling air pollution using Atmega328p IC.MQ7 sensor is used for sensing the emitted gas, and after crossing the standardized limit the solenoid valve opening and closing is controlled by relay card.
