# ESP32 Dual Ultrasonic Water Level Monitoring System ivyo ## Description This project is designed to measure water level of two tanks using ultrasonic sensors interfaced with the ESP32 microcontroller. The design leverages the processing power and wireless connectivity of the ESP32 to accurately monitor water levels and support automated water management processes. Key components include two ultrasonic sensors for precise distance measurement, robust voltage regulation using an LM2596 buck converter, and reliable power management circuits. Its modular design approach facilitates easy expansion and integration with other systems, making it an ideal solution for both DIY enthusiasts and professionals in automated fluid control and IoT applications. #ESP32 #UltrasonicSensor #WaterLevelSensor #LM2596 #VoltageRegulator #ModularDesign #IoT #DIYProjects #ElectronicsDesign #automation ## Project Details -
