摘要

通过使用基于 arduino 的半圆柱形电容器传感器,实现了基于橙子的甜度测量装置的设计。这项研究通过使用频率值为 10 KHz、100 KHz 和 1 MHz 的振荡器为电容器板提供输入。使用的振荡器是 XR-2206 型集成电路。橙子的甜度是用袖珍折射仪 Otago pal-α 测量的。对 16 个桔子进行了半圆柱形电容器传感器测试。由于测量结果的曲线图呈线性下降,因此在 100 千赫兹的频率变化中获得了最理想的测量结果。频率为 100 KHz 时的电压范围为 200 - 2000 mV,得到的糖度值在 13.8 - 16.7% 之间。橘子电压越高,橘子所含的 Brix 值就越低。Brix 值在 13.8 - 15.6% 之间的橙子甜度较酸,而 Brix 值在 16.7% 之间的橙子甜度较甜。工具测试结果显示,平均误差为 0.004%,工具准确度为 99.6%。

Rancang Bangun Alat Ukur Tingkat Manis Buah Jeruk Menggunakan Sensor Kapasitor Semi Silinder Berbasis Arduino
It has been realized the design of the orange based sweet level measuring device using an arduino based semi cylinder capacitor sensor. This study was conducted by providing input to the capacitor plates using an oscillator with a variety of frequency values of 10 KHz, 100 KHz, and 1 MHz. The oscillator used is the IC XR-2206 type. The sweet level of orange fruit is measured using a pocket refractometer otago pal-α. Semi cylinder capacitor sensor testing is carried out on 16 oranges. The most optimal measurement results are obtained in a 100 KHz frequency variation because the graph of the measurement results drops linearly. The voltage range at a frequency of 100 KHz is 200 - 2000 mV, with a brix value obtained between 13.8 - 16.7%. The higher the orange voltage, the lower the Brix value contained in oranges. Brix value 13.8 - 15.6% states the sweet level of orange fruit is sour, while the Brix value 16.7% states the sweet level of orange fruit is sweet. The results of testing the tool obtained an average error value of 0,004% and a tool accuracy value of 99,6%.
