Accurate aquaculture water quality monitoring is essential to guarantee the health aquatic breeding.To eliminate the effect of temperature on dissolved oxygen sensor and pH sensor, this study focused ontemperature compensation. Cubic polynomial fitting method was adopted to conduct temperature compensationanalysis of dissolved oxygen electrode, and the least square method was selected to conduct linear analysis ofthe relationship between pH value and voltage. Finally, temperature compensation models for dissolved oxygensensor and pH sensor were obtained. The experimental results showed that th...
