Prototype of simple mini-wave gauge using Microcontroller ESP32 on the laboratory scale

Abstract The limited availability of real-time wave data is needed for shipping safety and planning coastal areas. This monitoring system including the height direction gained to be used as a consideration in making decisions related management. study aims design create prototype simple mini-wave gauge test performance on laboratory scale. sensors this were ADXL335 vibration sensor detect movement GY-271 module with HMC5883L chip which was sensor. In experiment, generated by then received microcontroller ESP32 processing center. computer using Wi-Fi network well processed displayed an application that had been developed Embarcadero Delphi. Experiments resulted average range ± 6cm trough -4.5 cm crest 2.2 cm. validated ultrasonic at scale root mean square error obtained 1.34 Generally, device functions has high accuracy recording data.
