A team in Denmark has developed a sensor-based system which could help to tackle air pollution by detecting ammonia and other gases emanating from the agriculture sector.
Alongside chemical engineers and chemists, researchers from Aarhus University and the Technical University of Denmark worked on the technology as part of the Ecometa project, which is focused on cutting emissions connected to agriculture.
The researchers at the universities are focused on photonics, a term the European Commission has described as “the science and technology of light.” Details of their system have been published in the journal “MDPI Photonics.”
According to an announcement earlier this week, those involved in the project have produced an integrated optical sensor which “measures ammonia in the air using a laser, a gas sensor and hollow-core optical fibres.”
