Abstract

The earth is surrounded by air, a mixture of extremely important gases such as oxygen, carbon dioxide and nitrogen. These gases provide human and animals with oxygen for respiration to occur. In general, the air pollution in our daily life that getting worst. Besides that, air environment sometimes getting an unsatisfactory of smell such as garbage smell, smoke, and gases. For detecting this air odour, there are some technology create by human to check and detect the smell which are known as "electronic nose". Electronic nose or E-nose is an artificial olfaction device with a range chemical gaseous sensor used to analyse gas. This method is applied in this project by using MQ-135 sensor to detect odour and senses it. The Arduino NANO are used as the microcontroller of the project. The project will be controlled by the program in the Arduino IDE Software with coding C++. Next, the objective in this project is to create a portable device that can detect smell to used in specific smell sensor to detect air environment, can record a data of odour in air quality and lastly can collect the data and do comparison for analysis. The development of this portable device can help people detect with easy and save time to measure the level of smell that suits the air for human to breathing
