RANCANG BANGUN SISTEM KONTROL DAN MONITORING AIR TANDON DENGAN MEMANFAAT ULTRASONIC HC SR04 DAN OPTICAL TURBIDITY SENSOR BERBASIS INTERNET OF THINGS (IOT)

Water is an important basic need for daily life, but the availability and quality of water is often a problem, especially in areas that depend on water reservoirs. This research aims to design and build an Internet of Things (IoT)-based water reservoir water level and turbidity monitoring and control system powered by solar panels. This system uses Ultrasonic HC SR04 sensor to measure water level and Turbidity sensor to measure water turbidity. The ESP32 microcontroller serves as the control center that connects the system with the Blynk application, which enables real-time monitoring and control. In addition, solar panels are used to support the sustainability of the system by providing renewable energy. System testing was conducted to ensure the integration between the components works well. The test results show that the sensors can measure the water level and turbidity accurately, and the system functions as expected. This research provides an effective solution for automatic monitoring and management of reservoir water, with energy savings and monitoring that can be done remotely. Future research plans are to improve the accuracy of the sensor and optimize the system for long-term use
