Odor pollution in the environment will be considered, together with its sources and smattering, the physical and chemical properties of odor, odor emission regulations in selected countries, odor control technologies as well as the state-of-the-art instrumentation and technology that are necessary to monitor odor, e.g., chemical sensors, olfactometry, gas chromatography, and electronic noses. With today’s increasing levels of progress, residential areas are predictably built closer to odour generating facilities pharmaceuticals industries and chemical industrial plants. Odour measurements, which provide important information in the planning of the plants and odour treatment facilities, are needed to underpin the numerous decisions that will have to be made to reduce odour nuisance. An odour emission regularly consists of a multifarious mixture of many odorous composites. Analytical monitoring of individual chemical compounds present in such odour is usually not practical. As a result, odour sensory methods, in its place of instrumental methods, are normally used to measure such odour. Odour sensory methods are available to monitor odour both from source emissions and in the ambient air. These two different situations require different methodologies for measuring odour. Thus the sensitivity of the odour sensory method must be significantly greater for measuring ambient odour than for source odour emissions. For known compounds, the Odourstrong point can be steadfastly estimated by measuring the awareness of the chemical, while, for mixtures of unknown substances, sensory method is preferred. It consists of a sensor which is used to detect the presence of gases namely ammonia and hydrogen sulphide. As this is a daily activity, the sensors are also used to monitor them regularly for a better health. The main advantage of our model is that the sensor does a regular act in monitoring them from their daily activities. This paper describes the arduinouno based odor sensory measurement system used in kurkumbh industrial area.
