In addition to oxygen produced by photosynthesis the oxygen-increasing machine is necessary for maintaining the pool temperature to produce enough oxygen. In general the volume of dissolved oxygen required for the survival of is 5 ppm or more. When the volume of dissolved oxygen is less than 5 ppm will die. The main purpose of AC-powered aerator used in the aquaculture industry is to provide breeding species for oxygen consumption and maintain a stable production of flat products of water. However, the aerator can’t monitor the oxygen content resulting in the death of the breeding species because of lack of oxygen. Therefore this research proposes a transmitter system of oxygen sensing information using wind-solar power generation and ZigBee in oxygen sensing for giant grouper. The wind-solar power can be converted to AC power by the inverter for the supply of 24 hours a day. In addition to the supply of giant grouper aerator power, control temperature and energy saving in aquaculture industry, the system proposed in the study also provides the function of ZigBee oxygen contents monitoring in water and the signal transferring to a computer graphical user interface for the information of the oxygen content to operate the aerator. Thus the mortality in giant grouper can be effectively reduced.
