Abstract :
An optical fibre sensor has been developed for the monitoring of low level atmospheric ammonia. In-situ experimental tests within an agricultural cattle enclosure in the Republic of Ireland demonstrate the effectiveness of the developed sensor to accurately monitor concentration levels of between 0 and 2 ppm. Finally, a comparison with a commercially available sensor demonstrates the suitability of the developed sensor in terms of sensitivity and selectivity.
