精细的水质数据可以促进水资源的优化管理，由于人口增长，对安全水源的需求增加以及环境污染，水资源变得越来越稀缺。迫切需要具有成本效益，可靠，可重复使用和自主的水传感技术，可以提供准确的实时水质测量。在本文中，我们提出了一种微波传感器阵列的敏感元件工作在不同的频率在1 GHz到10 GHz的宽频带。与单个传感器系统相比，阵列的使用允许收集更多的信息。传感器阵列可以通过标准印刷电路板（PCB）技术以具有成本效益的方式制造。在这里，它是用各种污染物和参数值的水溶液进行测试的。测量并提供了不同污染物和参数值的水样的介电特性。
Fine-grained water quality data can facilitate the optimized management of water resources, which have become increasingly scarce due to population growth, increased demand for safe sources of water, and environmental pollutions. There is a pressing need for cost-effective, reliable, re-usable, and autonomous water sensing technologies that can provide accurate real-time water quality measurements. In this paper, we present a microwave sensor array with sensing elements operating at different frequencies in the wide frequency band of 1 GHz to 10 GHz. The use of array allows for collecting more information compared with a single sensor system. The sensor array can be fabricated in a cost-effective way through standard printed circuit board (PCB) technology. Here, it is tested with water solutions of various contaminants and parameter values. The dielectric properties of the water sample with different contaminants and parameter values are measured and provided as well.
