Abstract. High level of ammonia in poultry houses adversely impact poultry performance and well-being. Reliably quantifying in-house ammonia concentrations is important but challenging due to the harsh environment of the poultry house that affects the performance of monitoring methods for ammonia management. Three low-cost and robust metal oxide semi-conductor (MOS) ammonia sensors were evaluated in the lab for their responses to changing ammonia concentrations and a wide range of relative humidity (RH) levels. The Figaro TGS 2444 sensor was found to be superior and will be further tested and incorporated into a handheld device for monitoring ammonia levels in poultry houses.
