摘要

水盐度监测在许多行业，特别是渔业和农业中非常重要。因此，有必要建立一个能够解决现场障碍的无线水盐度传感器系统。本研究提出一种采用并联电容板模型的低成本无线水盐度传感器系统。利用非稳态多谐振荡器电路将与盐度成正比的电容效应转换为数字脉冲。利用wifi微控制器对这些脉冲的频率进行计数，并根据盐度与频率的关系特征进行逆变换。WIFI微控制器采集的水盐度数据通过网关WIFI传输到控制站单元(CSU)。测试结果表明，最大覆盖范围为30米的网关。尽管如此，使用网关WIFI可以增加无线水盐度传感器的覆盖范围。校正试验也表明，本仪器在测量水的盐度时误差为2.3%。

A Capacitive Model of Water Salinity Wireless Sensor System Based on WIFI-Microcontroller

Monitoring for water salinity is very important in many industries, especially fishery and farming. Therefore, it is necessary to build a wireless water salinity sensor system capable of tackling obstacles in the field. This research proposes a low-cost wireless water salinity sensor system using parallel capacitive plate model. Capacitance effect that is proportional to salinity value is transformed into digital pulses using a circuit of an a-stable multivibrator. Frequency of these pulses is counted using a WIFI-microcontroller and inverse transform is carried out according to the relationship characteristics of salinity and frequency. Water Salinity data acquired by the WIFI-microcontroller are then transmitted to the Control Station Unit (CSU) via gateway WIFI. Testing results show maximum coverage range of 30 meters to the gateway. Nonetheless, the use gateway WIFI can increase the coverage range of this wireless water salinity sensor. Calibration tests also indicate an error of 2.3% in water salinity measurement by the instrument developed here.
