Solid State Chemical Sensors: Technologies and Applications

The agricultural industry needs to be more accountable with regard to environmental pollution. This has arisen because the adoption of increasingly intensive farming methods in agriculture, with the associated production of significant quantities of solid and gaseous waste emissions that has, in recent years, been linked to adverse environmental change. Solid state chemical sensors are highly desirable, but available technology still lacks robustness for use in the agricultural field. This paper reviews sensing, sampling and measurement technology applicable to real-time monitoring of gaseous fluxes.
