IoT-Based Water Bill Calculation Automation System Prototype for PAMSIMAS

Abstrak

Water is an essential resource that supports human life and contributes to improving community welfare. Clean water availability is not only required for basic needs but also influences health and social well-being. The Community-Based Drinking Water and Sanitation Program (PAMSIMAS) aims to expand access to clean water in rural areas. However, water usage recording is still performed manually, which is time-consuming, prone to errors, and inefficient. This study aims to develop a prototype of an automated water billing system based on the Internet of Things (IoT) integrated with a website. The system employs a Water Flow Meter sensor connected to a NodeMCU ESP8266 microcontroller to measure water flow, with data transmitted in real-time via the internet and displayed on the website. The website provides features such as water consumption recording, automatic billing based on applicable tariffs, and monthly usage reporting. The research method includes literature study, field observation, hardware design, software development, and system testing. The test results show that the prototype successfully performs all test scenarios, displaying water usage data in real-time, calculating bills automatically, and storing data in a database with 100% accuracy. Therefore, the developed prototype functions properly and meets the research objectives.
