Water is a quintessential element for the survival of mankind. Its variety of uses means that it is always in a constant state of demand. The supply of water most primarily comes from large reservoirs of water such as lakes, streams, and the ocean itself. As such, it is good practice to monitor its quality to ensure it is fit for human consumption. Current water quality monitoring is often carried out in traditional labs but is time consuming and prone to inaccuracies. Therefore, this paper aims to investigate the feasibility of implementing an Arduino-based sensor system for water quality monitoring. A simple prototype consisting of a microcontroller and multiple attached sensors was employed to conduct weekly onsite tests at multiple daily intervals. It was found that the system works reliably but is reliant on human assistance and prone to data inaccuracies. The system however, provides a solid foundation for future expansion works of the same category to elevate the system to being Internet of Things (IoT) friendly.

使用基于Arduino的传感器进行水质监测

水是人类生存的精髓。它的用途多种多样，意味着它始终处于需求的恒定状态。供水主要来自大型水库，例如湖泊，溪流和海洋本身。因此，优良作法是监控其质量，以确保适合人类食用。当前的水质监测通常在传统实验室中进行，但是很耗时并且容易出错。因此，本文旨在研究实现基于Arduino的传感器系统进行水质监测的可行性。一个由微控制器和多个连接的传感器组成的简单原型用于以多个每日间隔每周进行一次现场测试。发现该系统运行可靠，但是依赖于人工协助并且容易出现数据不正确的情况。但是，该系统为将来进行相同类别的扩展工作提供了坚实的基础，从而将系统提升为物联网（IoT）友好型。
