People usually associate hydration with thirst. This is actually the worst way to determine human are properly hydrated. When one feels thirsty, this is actually an indicator human are already dehydrated. Human body is made up of almost 60 percent water, human might not feel the need to drink water because human is abundant with it. At the same time, human body needs constant refill since we use it in every process and activity inside our body. However, regarding water pH nowadays is the increasing occurrence of water resources with imbalanced pH levels, including both excessively acidic and alkaline waters, which can pose risks to human health and the environment. The drinking water alert system presented in this project addresses the critical issue of ensuring water quality and safety. The system uses a weight sensor and a pH sensor as input devices and an Arduino microcontroller as the central control device. The system continuously monitors water volume and pH levels and provides alerts to users using an LCD display, LED indicators, and a buzzer, ensuring timely notifications of potential water quality issues. In addition, this project is to create an automated system and reliable drinking water alert system that validly detects and notifies users about variation from safe water conditions. The Arduino microcontroller operates as the system’s brain, processing data from the weight and pH sensors and producing the appropriate outputs based on predefined thresholds. The alert mechanism contains of an LCD display, LED indicators, and a buzzer. LCD display, which also shows important information such the pH level and amount of water that is currently present. The LED indicators offer visual cues, signalling the problem of the water quality issue. The buzzers induce audible alerts, ensuring that users are quickly notified even in situations where visual notifications may be missed. Nevertheless, this project shows the effectiveness of using a weight sensor and a pH sensor with an Arduino microcontroller to produce a drinking water alert system. The combination of the input sensors and the output devices give users with real-time monitoring and timely notifications regarding potential water quality issues, enhancing the safety and wellbeing of individuals consuming the water supply.
