Air pollution monitoring and control is of extreme importance as it has a direct impact over the humans, and their heath conditions. Accordingly we use a wireless sensor network at the chimney tip, acting as a filter which evaluates all the toxic output by sensors (MG811,MQ6, MQ135), which in turn controlled by a Atmega16 microcontroller's transmitting unit. It is placed at the industrial administration sector, and receives all the sufficient outputs from the transmitting unit. The outputs are simulated graphically and the extend of over-toxic waste are also evaluated under two conditions. The primary condition is to alarm the pollution control sector of both the private and the government department, and the secondary condition is to trip the grid of the industrial power source once the toxic output content is uncontrollable or is above the mark of the default toxic limit as defined by the pollution control board. This part of the system can also be linked with the press and the media for future references and proof for toxic emissions. Thus the following paper deals with the automated switching and analyzing of the industrial toxic output content and also acts as a temporary controller of the same.
