摘要
依据电流法测量原理,系统使用STM32单片机识别溶解氧传感器上的电信号来测量溶解氧值,同时针对温度、盐度以及大气压对测量结果的影响进行补偿。对比实验结果表明,设计的溶解氧测量仪简易方便,精度高,反应迅速,可重复性好,实用性强。
Based on the measurement principle of cun＇ent method,the designed system used STM32 MCU to recognize the current of dissolved oxygen sensor. In addition, the system compensated the influence of temperature, salinity and atmospheric pressure on the measured results.The comparison experiment results show that the designed system is ease of use ,high-precision, quick-response, good-repeatability and trong practicality.
