Implementasi Sistem Monitoring dan Kontrol Sirkulasi Air Menggunakan Internet of Things pada Desa Liang Pematang

Abstract

Water plays a crucial role as a source of life for humans. Its presence is essential to fulfill our basic needs. However, water must remain free from harmful contaminants that can pose health issues. Water quality is often assessed based on turbidity levels. Sustainable water management is necessary, considering both the amount and quality of water suitable for human use. This research presents a water circulation monitoring and control system based on the ESP32 microcontroller, integrated with the ThingSpeak cloud platform and WhatsApp messaging service. The system is equipped with turbidity and pressure sensors to collect water quality and pressure data within the pipeline circulation. The ESP32 acts as a sensor node and controller, transmitting data acquired from the sensors to ThingSpeak for real- time storage and analysis. Users can monitor water quality and pressure through the ThingSpeak dashboard. Additionally, the WhatsApp service is used to send warning notifications when the turbidity level is high and serves as a control medium for the system. The system employs a stop valve integrated with a servo motor, allowing the valve to open and close automatically according to the program given. When the water is turbid, the stop valve opens, directing the water to a filter. If the water is clean, the system directly delivers the water to consumers. The implemented system will be beneficial for water circulation monitoring and control in Liang Pematang Village.
