Abstract

Monitoring water consumption with the Internet of Things (IoT) is a significant innovation in improving water utilization efficiency in multi-story buildings. This research develops a monitoring system on a three-story building prototype, which combines the MQTT protocol, the Node-Red visualization platform, and two sensors: the YF-B6 and the analog water flow meter sensor. The YF-B6 sensor measures the number of pulses from the water flow to determine the volume, flow rate, and velocity of the water, while the analog water flow meter sensor is integrated with the ESP32-CAM module to capture images of the water flow indicator and process them into volume values using image processing. Data from both sensors are sent to the cloud MQTT broker and visualized interactively through the Node-Red dashboard. This system is implemented on a three-story building prototype to replicate the distribution and monitoring of water usage on each floor. The research results indicate that this system can provide water consumption data with an error percentage of 0.2% and an absolute error of 0.03 m³. This system will also be used for the industrial automation workshop learning module to introduce the Internet of Things (IoT) in an educational environment.

Abstract

Monitoring electrical power consumption in the PENS Smart Automation Workshop Building is a fundamental step in an effort to optimize efficient resource management. In this research, a monitoring system is developed that is able to accurately measure, record, and store data on the use of electric power in a miniature building model. This system uses the PZEM-004T sensor module as a measuring instrument for electrical parameters combined with Internet of Things (IoT) technology. This system uses the PZEM-004T sensor module as a measuring instrument for electrical parameters combined with Internet of Things (IoT) technology, and an initial study of BACnet communication integration as an additional protocol. The research includes a literature study related to the basic concepts of electric power monitoring, Modbus and BACnet communication protocols, and IoT technology. System design involves the integration of hardware and software with an IoT-based user interface to support data acquisition and visualization. The collected data is sent via MQTT communication to the cloud and displayed in graphical form via the Node-RED platform, allowing real-time monitoring of electric power consumption with an interactive and customizable dashboard display. The test results show that the system is able to record data in real-time and present accurate information, so that it can be the basis for making energy management decisions. This research contributes to the development of a simple energy monitoring system that can improve efficiency in monitoring energy use with a warning if there is an overload.
