A new intelligent electronic nose system for measuring and analysing livestock and poultry farm odours

Abstract

This paper introduces a new portable intelligent electronic nose system developed especially for measuring and analysing livestock and poultry farm odours. It can be used in both laboratory and field. The sensor array of the proposed electronic nose consists of 14 gas sensors, a humidity sensor, and a temperature sensor. The gas sensors were especially selected for the main compounds from the livestock farm odours. An expert system called "Odour Expert" was developed to support researchers' and farmers' decision making on odour control strategies for livestock and poultry operations. "Odour Expert" utilises several advanced artificial intelligence technologies tailored to livestock and poultry farm odours. It can provide more advanced odour analysis than existing commercially available products. In addition, a rank of odour generation factors is provided, which refines the focus of odour control research. Field experiments were conducted downwind from the barns on 14 livestock and poultry farms. Experimental results show that the predicted odour strengths by the electronic nose yield higher consistency in comparison to the perceived odour intensity by human panel. The "Odour Expert" is a useful tool for assisting farmers' odour management practises.

An wireless electronic nose network for odours around livestock farms

“…In our previous study, an electronic nose consisting of a sensor array and an intelligent analysis system was developed. Experimental results proved its capability of producing objective odour and consistent odour measurement [1].…”

“…Electronic noses have been developed for monitoring agricultural environment [1], [2], [3], [14]. In our previous study, an electronic nose consisting of a sensor array and an intelligent analysis system was developed.…”

A Web-Based Collaborative System for Remote Monitoring and Analysis of Livestock Farm Odours

“…Sensor signals are delivered to and stored on a local computer for future processing. The detailed information about the wireless sensor networks can be found in Pan and Yang (2009), and the development of electronic noses is described in details in Pan and Yang (2007a). The wireless sensor networks provide the collaborative system with remote odour monitoring ability.…”

Development of an E-Nose Using Metal Oxide Semiconductor Sensors for the Classification of Climacteric Fruits

“…The E-Noses is more reliable and superior than human sniffing in case of fatigue, infections, mental state, subjectivity, exposure to hazardous [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. We have verified the functionality and accuracy of the device with a program we developed, written in LabVIEW.…”
