Abstract
MQ137 sensor has been successfully used to control ammonia concentration automatically and realtime in a catfish pond water. The ammonia testing was carried out by bubbling pond water to vaporize ammonia gas to sense by the sensor. The result showed that the could detect the ammonia concentration below 1 ppm and it instructed the water pump to flow the water throught a water filter to reduce the ammonia concenration. The aplication of pond water quality control has resulted in a reduction in the number of catfish deaths due to poisoning.
