This article presents the design of the pH and Dissolved Oxygen (DO) measurement and control systems. The systems are include pH sensor (Haoshi) and dissolved oxygen sensor model Raindrops Module. These are the measuring devices that send signals to Arduino processing board and the processing values obtained from the measuring devices then control pH and …
The research aims to develop of water renewable catfish farming system by solar energy and compare the water quality from catfish farming with cement ponds with solar water renewable systems in Ban Na Mai Phai Community in Nakhon Si Thammarat Province. The needs and the problems of the catfish farmers were surveyed. Then, the farming system was developed.
