In a widespread current scenario, carbon nano tube is one of the potential tools for the advancement of the technologies specially in the chemical sensor monitoring for environment and health care system. A pyrolysis technique at varying temperature growth was implied for the amalgamation defective controlled carbon nano tube. To monitor the oxygen (oxygen sensing) under standard pressure and temperature a fabricated device with random net of carbon nano tubes were used. A non-structured metal oxide sensor was intended to determine the oxygen by using carbon nano tube application. Sensor based redox, photocatalyst (titanium oxide) and Polymer matrix composites such as ethylene vinyl alcohol copolymer were used for its formulation
