In this paper, an innovative device to measure odour emission known as Electronic Nose (ENs) is presented. These devices allows a continuous monitoring in situ of odour emisions and are able to detect quick changes in the emission rate of odours avoiding a time-consuming use of a laboratory. In this article, the author comments the application of different sensors for a each particular case and compare in the use of an EN in different activities. In addition, a short introduction about the different e-noses available in the market is presented.
