KALIBRASI SENSOR TEKANAN HK3022 SEBAGAI PENGUKUR TINGGI MUKA AIR LAUT
In making sea level instruments using sensors. Calibration of the sensors used is required. Measurements are needed to get the actual measurement result. In this study, using the Arduino Mega 2560 Pro Mini Microcontroller, the Micro SD Card Module as data storage, and the HK3022 Pressure Sensor as a water depth data reader. The results showed that the coefficient of determination was 0.999 with a percentage of 99.001%. The read error value is 0.07. The level of accuracy of sensor readings to the actual water depth is 3.24 with a percentage of 96.76%. The standard deviation of the sensor calibration on the water depth reading is 29.29 and the coefficient of variation is 0.7. The values from these data indicate that the HK3022 pressure sensor is quite accurate and capable of measuring depth.
