Abstract

This research proposes a prepaid water consumption control system that integrates an online top-up feature with notifications via the LINE application. The system consists of two main components: an online top-up platform, where water consumers scan a QR code, select the desired amount, upload proof of payment, and send the data to the water consumption control unit; and the water consumption control unit, which sends notifications to water consumers through LINE about top-ups, water flow rates, remaining balances, low water availability, and system shutdowns. Water consumers can also monitor water flow rates, account balances, and available water volumes on an LCD screen. The system’s performance was tested across all functionalities, from QR code-based top-ups to water consumption control and automatic shutdown when the balance is depleted. The system operated accurately, effectively sending LINE notifications and displaying data on the LCD. Additionally, a comparison of water consumption readings between a standard water meter and the developed system, using 5 liters (5x10-3 cubic meters) of water over ten trials, showed a measurement error of 1.48%.
