Low Cost Optical Ammonia Monitor

Ammonia is a toxic gas with a strong odor that is produced naturally in the biological degradation of organic matters and animal waste. Currently available ammonia sensors are either sensitive but too expensive or affordable but not able for an unattended, long term monitoring. Searchlight Sensors proposes to develop a low cost, small ammonia monitor with sufficient sensitivity and time response for the air quality monitoring inside the livestock confinement houses. We anticipate our ammonia monitor will be useful in smart ventilation control systems of animal confinement buildings, ammonia leak monitoring in fertilizer manufacturing plants and ammonia-based commercial refrigerated storage.
