IoT Architectural Design for Household Water Quality Control

Access to clean and safe water is essential for daily needs and the overall well-being of society. However, the water quality in Indonesia falls below health standards, leading to various health and environmental issues. To address this challenge, this research proposes the implementation of simple water filters in households combined with the utilization of Internet of Things (IoT) technology for real-time water quality monitoring. The system involves filtering the water supplied by the Public Water Supply (PDAM) using activated carbon, zeolite, and silica sand as filtration components. The filtered water is then stored in household water storage tanks. Within the tank, a turbidity sensor measures water cloudiness, while a pH sensor detects the pH level. These sensors are connected to a microcontroller, which communicates with a cloud database through a Wi-Fi module. A mobile application provides users with real-time monitoring of water quality, displaying turbidity and pH values on a dashboard. Device effectivities are measured by controlled experiments. This IoT -based household water quality control system aims to improve water quality, enhance monitoring capabilities, and promote healthier water consumption practices.
