Real-time Monitoring Systems for Malodor Compounds Sources using Ubiquitous Sensor Networks

Abstract

Maintenance systems are demanded to manage malodor-information and deal effectively with the odor-related civil complaints by constructing the database for sources of malodor compounds in real time. In this paper, to carry out these tasks, a real-time monitering system for malodor based on ubiquitous sensor networks(USN) is presented. The constructed monitering system stores the malodor data collected periodically from industrial complex into the database and shows in real time the circumstances of the odor sources being emitted around the industrial complex by indicating on the map where it is taking place. Besides, by clicking an icon indicating the sensor node on the map, we can figure out what firms are located near the malodor source and possible material related with those firms. The proposed system is considered to enhance the efficiency of management of malodor-emitting firms based on the malodor-related information.

Odorant binding proteins from Hermetia illucens: potential sensing elements for detecting volatile aldehydes involved in early stages of organic decomposition

“…Because conventional analytical instruments could not be readily used for malodour monitoring in the field, many researchers have resorted to using 'electronic nose' techniques (recently reviewed by Covington et al [16]). Key publications include that of Schiffman and Osuna who reported the use of such a system for evaluating the odours from swine operations [1], Stuetz et al for sewage odour monitoring [17], Tanaka et al for measurement of oral malodour [18], Wilson [19] for hazardous gases, Schnürer et al [20] for detection of fungal volatiles indicative of food spoilage, together with networks of sensing devices for malodour monitoring [21].…”
