<![CDATA[Access to clean water is a vital necessity for communities, particularly in areas that rely on borehole wells as their primary water source. However, manually operating these pumps without an adequate monitoring system can lead to issues such as dry-running, energy waste, and pump damage caused by electrical current irregularities. This study aims to implement an Internet of Things (IoT)-based monitoring system for borehole pump water levels and electrical current using an ESP32 microcontroller. Unlike systems that focus solely on water availability, this study integrates water level monitoring (via an HC-SR04 sensor), electrical current monitoring (via an ACS712 sensor), and a low-water protection mechanism (using a float switch) into a unified system featuring real-time Telegram notifications. The research methodology encompasses a literature review, field observations, system design, hardware and software implementation, and functional testing of each system component. Test results demonstrate that the HC-SR04 sensor successfully detects water level changes, the ACS712 sensor accurately reads the pump's electrical current, and the system effectively triggers automatic protection via a relay when low water levels are detected. Additionally, the system activates a buzzer alarm and sends warning notifications to the user via Telegram. Functional testing confirms that all system components operate according to the design, offering a practical solution to enhance the safety and reliability of borehole pump operations through real-time remote monitoring.]]>
