PROTOTYPE DESIGN AND DEVELOPMENT OF AN IOT-BASED ELECTRONIC DEVICE MONITORING AND CONTROL SYSTEM AT BAITUL MARIFAH MOSQUE POLTEKBANG SURABAYA USING A WEBSITE INTERFACE

Abstract

Electrical energy usage in mosques is often inefficiently controlled due to the lack of an integrated automatic monitoring
and control system. This results in power wastage and difficulty in managing electronic devices that operate for long
periods of time. To address these issues, this study aims to design and build an Internet of Things (IoT)-based electronic
device monitoring and control system that is integrated with a website interface and can be accessed in real time. This
system is designed to support the implementation of the smart mosque concept through energy efficiency and electricity
management automation. The study uses a 4D (Define, Design, Develop, Disseminate) R&D model approach, by
integrating an ESP32 microcontroller, a PZEM-004T sensor to measure electrical parameters (Voltage, current, power,
and energy), and Firebase as a cloud-based data communication platform. Testing is carried out by assessing the
validator to transmit data readings and device control stability via the website. The results show that the system is able
to provide current, Voltage, and power data readings in accordance with field data compared to standard measuring
instruments in the form of a Clampmeter and performs control functions responsively and stably. This research provides
a practical contribution in the development of a cost-effective and easy-to-implement system for digitalizing energy
management in mosques, as well as being the first step towards implementing IoT-based micro-scale smart building
technology .
