Abstract
A water pH control device in catfish farming has been successfully made and tested. The work principle of this device has been designed to maintain the pH of catfish pond water in the range of 6,5-8,5 and it was found that if the Ph value was outside this range, the sensor ordered the water pump to automatically and in realtime drain the pond water throught a filter to return the Ph to the specified value. Thus, the application of this sensor has successded in reducing catfish deaths due to strees.
