pH传感器温度补偿模型研究
Research on pH Sensor Temperature Compensation Model
摘要
Abstract
Water quality of pH online measurement is very important to improve the health aquaculture, wireless sensor networks system for pH monitoring based on wireless sensor networks and pH sensor is designed here. To eliminate the effect of temperature on the measurement results, a temperature compensation model of pH sensor has been proposed here,the model measuring pH and temperature by pH sensor and PT100,and using the least squares method to analyze the linear relationship between pH and voltage, establishing a pH sensor temperature compensation model. The results show that,the compensation model has high measurement accuracy,and it could be realized a more accurate in pH online measurement.关键词
