Introduction

In today's digital era, the measurement and recording of clean water consumption is still largely done manually, with a payment method that usually relies on a postpaid system. This approach can lead to inaccuracies in recording water use and discomfort for users. To overcome this problem, this research aims to develop a microcontroller-based prepaid digital water meter that facilitates the recording and management of water consumption with prepaid payment methods, which are certainly more efficient and transparent.

Background

The current manual system of measuring and recording clean water consumption is not only time-consuming but also prone to errors. The postpaid system, which relies on users receiving a bill for their water consumption, can be inconvenient and may lead to disputes over the accuracy of the bill. Moreover, the lack of transparency in the payment process can lead to a lack of awareness among users about their water consumption habits. Therefore, there is a need for a more efficient and accurate system that can record and manage water consumption in real-time.

System Design

The microcontroller used in this project is the Arduino Uno R3, which is equipped with various components that enable the system to function effectively. These components include:

Water Flow Sensor: This sensor measures the volume of water flowing through the system, allowing for accurate recording of water consumption.
Solenoid Valve: This valve functions as a water flow regulator, ensuring that the water flow is controlled and measured accurately.
Keypad: This keypad is used by the user to enter the token code, which is required for prepaid payment.
LCD 20X4: This LCD display shows water usage data and token code status entered by the user.
SIM800L Module: This module is used to send data to the database, ensuring that the system is connected to the internet and can be accessed remotely.

The system is powered by 7.2AH/12V batteries and 12V/1A adapters, providing a reliable source of power for the system.

Data Management

The system uses MySQL as a database to store water consumption data, which can be accessed remotely through a website. The user interface is developed using HTML and CSS on the front-end side, and PHP on the back-end side. This allows for a user-friendly interface that can be accessed by users to view their water consumption data.

Results

The results of the study showed that the system was successful in recording water consumption automatically and limiting water use in accordance with the number of tokens added by the user. The use data can be seen directly in the LCD module, as well as recorded in the website display provided to facilitate access to information for users.

Conclusion

The development of this microcontroller-based prepaid digital water meter offers ease and efficiency in recording and managing clean water use. By adopting the latest technology, this system not only makes it easy for users to make prepaid payments but also ensures transparency and accuracy in recording. Through this innovation, we can move towards more sustainable and efficient management of water resources.

Future Work

Although this system shows promising results, there are measurement errors detected at 1,512% of the total measurement. This indicates the need to increase accuracy and calibration in the measuring instrument to ensure the reliability of the data obtained. Future work should focus on improving the accuracy of the measuring instrument and implementing a more robust calibration process to ensure the reliability of the data obtained.
