Abstract
Gaseous ammonia within confined animal production facilities can be detrimental to the health of both workers and animals, ultimately having a negative effect on production economics. An analog device for measuring and controlling gaseous ammonia levels within confined animal production facilities was developed. The device consists of two primary circuits, the measurement circuit and the control circuit, contained on a single PCB. The device was calibrated using GASTECH 3L ammonia detector tubes as the standard. The calibration had an R² of 0.990 and an RMSE of 1.314 ppm. The device was tested both in the laboratory and under field conditions at a layer farm, and was found to be capable of detecting gaseous ammonia. At a confidence level of 95%, there was no significant difference between the device readings and detector tube readings. IN regulating ammonia concentration levels, the device functions as a controller for activating and deactivating the actual control measure such as a ventilation system.
