This study developed and evaluated an IoT - Researchers proposed AquaFy: Water Dispenser based Water Dispenser Monitoring System with SMS Monitoring System using IoT with SMS Notifications to Notifications for staff and maintenance personnel. solve this urgent problem using IoT and SMS Conducted at Iloilo State University of Fisheries Science notifications. AquaFy uses cutting - edge technology to and Technology from March to November 2024, the monitor the water level in the dispenser in real time. When resear ch utilized a descriptive developmental method and the water level drops below a predefined threshold, the SDLC - Waterfall model. Tools such as Arduino IDE, authorized Personnel receive an instant SMS alert PyCharm, and Semaphore API were employed, alongside prompting timely action to refill the dispenser. This hardware components like the ESP8266 NodeMCU, Coin proactive approach eliminates the need for manual Acceptor, Water Flow Sensor, Water Pump, and LEDs . monitoring, reduces the risk of water shortage in cidents, Usability was assessed using the System Usability Scale and promotes a healthier and more efficient facility (SUS), involving one staff representative from each environment. 1.2 ISUFST - SEC course and 306 randomly selected students. The system achieved an outstanding SUS score of 96.27, 1.2 Objectives of the Study ranked "A+" within the 96 - 100 percent ile range, This study aimed to develop the AquaFy : Water indicating exceptional usability. The AquaFy system Dispenser Monitoring System using IoT with SMS automates water dispenser operations, reducing labor Notification. Specifically, this study aimed to: costs and downtime while enhancing maintenance through real - time alerts and remote monitoring. The results 1. develop AquaFy : Water Dispenser Monitoring demonstrate that the system is a cost - effective and System using IoT with SMS Notification to promptly practical tool for improving operational efficiency, with inform authorized Personnel when the water level in a significant usability and functionality benefits. dispenser falls below a predefined threshold;
