Development of a New Electronic Nose for Odour Measurement Utilizing Wireless Sensor Networks

The development of an electronic nose for data dissemination via a wireless network is presented in this paper. The design is tailored to odour emissions, and meteorology around pork farms and utilizes four ad-hoc gas sensors as well as two extraneous temperature and humidity sensors to aid in the odour monitoring and analysis of pork odour. Empirical data was gathered and analyzed through experiments using a proven chemical recipe that closely mimics that of pork odour. Thus far the electronic nose has yielded highly qualitative results as compared to that expected of pork odour and has also exhibited the ability to transfer data across a network.
