Abstract

Long lasting, inexpensive, and maintenance free systems are not currently available for the continuous sensing of ammonia emission from animal manure. Development of these sensors will provide information for the regulation of ventilation and manure management/amendment to protect animal and worker health and the environment. The overall objective of the project is to study feasibility of such a new sensor technology for sustainable monitoring of ammonia emissions from animal manure inside and outside of animal feeding or manure storage/management facilities. The sensor is based on simple and robust colorimetric method of spectroscopic measurement of reversible change of the color of a patent pending highly sensitive nano-composite reagent film in response to ammonia. The reagent with the same ingredients, but with either low or high doping rate, can be used for measuring levels of ammonia respectively few centimeters or few hundred meters from manure. This brings the
