Abstract
PurposeThe purpose of this paper is to provide a review of environmental sensing technologies and applications and to consider briefly the research effort.Design/methodology/approachThis paper describes environmental sensing strategies and technologies for air, water quality and other monitoring applications. It concludes with a brief overview of research.FindingsAs a consequence of legislation, a technologically diverse family of sensors are used in a wide range of portable and fixed instruments to determine numerous polluting compounds entering and present in the environment. These play a critical role in protecting the environment, maintaining public health and monitoring global phenomena such as ozone depletion and artificial global warming. There is a widespread and technologically diverse research effort.Originality/valueThis paper provides a detailed insight into the sensors and instruments used in environmental monitoring.
