Pengelolaan tandon air secara konvensional masih menghadapi berbagai kendala, seperti keterlambatan pengisian, pompa tetap beroperasi saat sumber air kosong, serta tidak tersedianya sistem pemantauan jarak jauh yang dapat menyebabkan pemborosan energi dan risiko kerusakan pompa. Penelitian ini bertujuan merancang dan mengimplementasikan sistem monitoring dan kontrol otomatis pengisian tandon air berbasis Internet of Things (IoT) menggunakan ESP32 dan sensor ultrasonik JSN-SR04T. Metode penelitian yang digunakan adalah Agile Development yang meliputi tahap perencanaan, analisis kebutuhan, perancangan sistem, pengembangan, pengujian, dan evaluasi. Sistem memanfaatkan dua sensor ultrasonik untuk mendeteksi level air pada tandon atas dan bawah, relay serta kontaktor sebagai pengendali pompa, dan aplikasi Blynk sebagai media monitoring serta kontrol melalui smartphone. Pompa bekerja secara otomatis saat level air berada di bawah 30% dan berhenti ketika mencapai 90%, serta dilengkapi fitur notifikasi untuk mendeteksi kondisi abnormal, seperti sensor error, pompa gagal beroperasi, dan kondisi dry run. Hasil penelitian menunjukkan bahwa sistem mampu melakukan monitoring dan kontrol pompa secara real-time, bekerja secara stabil sesuai logika yang dirancang, meningkatkan efisiensi penggunaan air dan energi, serta mengurangi risiko kerusakan pompa. Dengan demikian, sistem ini dapat menjadi solusi yang efektif, andal, dan responsif dalam pengelolaan tandon air berbasis IoT.

Conventional water tank management still faces several challenges, including delayed water refilling, pump operation when the water source is empty, and the absence of a remote monitoring system, which may lead to energy waste and pump damage. This study aims to design and implement an Internet of Things (IoT)-based water tank monitoring and automatic filling control system using an ESP32 microcontroller and JSN-SR04T ultrasonic sensors. The research employed the Agile Development method, consisting of planning, requirements analysis, system design, development, testing, and evaluation. The proposed system utilizes two ultrasonic sensors to measure the water levels in the upper and lower tanks, while a relay and contactor are used to control the water pump. The Blynk application serves as the monitoring and control platform via a smartphone. The pump operates automatically when the water level falls below 30% and stops when it reaches 90%. The system is also equipped with notification features to detect abnormal conditions, such as sensor errors, pump failures, and dry-run conditions. The results indicate that the system is capable of performing real-time monitoring and pump control, operates reliably according to the designed control logic, improves water and energy efficiency, and reduces the risk of pump damage. Therefore, the proposed system provides an effective, reliable, and responsive solution for IoT-based water tank management.
