Abstract

Air kebutuhan penting bagi kehidupan sehingga kualitas perlu secara dijaga agar tetap layak digunakan. Permasalahan yang sering terjadi adalah sulitnya memantau kualitas air secara langsung dan terus menerus. Oleh karena itu penelitian ini bertujuan untuk merancang dan membangun sistem monitoring kualitas air secara realtime berbasis IoT (Internet Of Things) mengunakan sensor Total Dissolved Solid (TDS) dan ESP 32. Metode yang digunakan adalah Research and Development (R&D) yang meliputi tahapan pengumpulan informasi, perencanaan, pengembangan produk, uji coba, revisi hingga produk siap digunakan. Sistem yag dibangun terdiri dari sensor Total Dissolved Solid (TDS) untuk mengukur zat terlarut, sensor DS18B20 untuk mengukur temperatur air, ESP 32 sebagai pengendali utama serta LCD OLED dan aplikasi Blynk sebagai media monitoring. Hasil penelitian menunjukkan bahwa sistem mampu membaca dan mengirimkan data kualitas air secara realtime melalui jaringan internet. Berdasarkan pengujian nilai TDS diklasifikasikan menjadi tiga kategori yaitu air jernih (0-300), air agak keruh (300-600) dan air keruh (600-1000) semakin tinggi nilai TDS kualitas air semakin buruk. Sistem juga memungkinkan pengguna memantau kondisi air dari jarak jauh melalui smartphone. Dengan demikian sistem monitoring kualitas air berbasis IoT dapat membantu meningkatkan efisiensi dalam pemantauan kualitas air serta memberikan informasi yang cepat dan akurat kepada pengguna Kata Kunci : IOT (Internet Of Things), ESP32, Sensor TDS, Kualitas Air, Monitoring realtime ================================================================================================= Water is an essential need for life so that its quality needs to be maintained to remain suitable for use. A common problem is the difficulty of monitoring water quality directly and continuously. Therefore, this study aims to design and build a real-time water quality monitoring system based on IoT (Internet of Things) using Total Dissolved Solid (TDS) sensors and ESP 32. The method used is Research and Development (R&D) which includes the stages of information collection, planning, product development, testing, revision until the product is ready for use. The system built consists of a Total Dissolved Solid (TDS) sensor to measure dissolved substances, a DS18B20 sensor to measure water temperature, an ESP 32 as the main controller and an OLED LCD and Blynk application as monitoring media. The results of the study show that the system is able to read and transmit water quality data in real time via the internet network. Based on TDS testing, water is classified into three categories: clear water (0-300), slightly cloudy water (300-600), and cloudy water (600-1000). The higher the TDS value, the worse the water quality. The system also allows users to monitor water conditions remotely via smartphone. Thus, an IoT-based water quality monitoring system can help improve efficiency in water quality monitoring and provide fast and accurate information to users.
