Abstract

Penelitian ini merancang dan mengimplementasikan sistem pemantauan ketinggian dan volume air berbasis teknologi sensor kapasitif yang terintegrasi dengan mikrokontroler ESP32, protokol komunikasi MQTT, dan platform Home Assistant. Penelitian ini bertujuan untuk mengatasi kendala karakteristik respons sensor kapasitif yang bersifat non-linear dalam mengukur permukaan fluida. Alur eksekusi alat diawali dengan akuisisi sinyal mentah kapasitansi melalui Touch Pin ESP32 yang terhubung ke elektroda sensor pada kolom objek ukur. Untuk mengatasi masalah non-linearitas, sistem menerapkan mekanisme auto-kalibrasi otomatis yang dipicu secara nirkabel melalui antarmuka Home Assistant. Saat mode kalibrasi aktif, ESP32 mengontrol sakelar pintar untuk menyalakan pompa pengisi air dan merekam sampel data pembacaan sensor secara periodik selama proses pengisian, yang kemudian dibekukan dan disimpan ke dalam memori Non-Volatile Storage (NVS) Flash sebagai tabel acuan kalibrasi.

This study designs and implements a water level and volume monitoring system based on capacitive sensor technology integrated with an ESP32 microcontroller, MQTT communication protocol, and the Home Assistant platform. This research aims to address the limitations of the non-linear response characteristics inherent in capacitive sensors when measuring fluid levels. The execution flow of the system begins with the acquisition of raw capacitance signals via the ESP32 Touch Pin connected to the sensor electrode within the measurement column. To overcome the non-linearity issue, the system implements an automated self-calibration mechanism triggered wirelessly through the Home Assistant interface. When the calibration mode is active, the ESP32 controls a smart switch to activate the water filling pump and periodically logs sensor reading data samples throughout the filling process, which are subsequently frozen and saved into Non-Volatile Storage (NVS) Flash memory as a calibration reference table.
