Automatic Dehydration Level Detection Devices

Abstract

Dehydration is a condition that occurs when the loss of body fluids exceeds the amount entered in the body so that it can disrupt the balance of minerals in body fluids. Most people do not feel thirsty until finally, they experience a period of severe dehydration, which can cause physical, cognitive, fatigue; if not corrected immediately can cause death. The purpose of this study is to design a dehydration and urine pH detection devices automatically. The contribution of this study is that this device is equipped with urine pH measurement and automatic body fluid calculation. This device is able to detect urine color levels, read urine pH values ​​, and provide information on body fluids needed to treat the patient's condition when detected. The sensors used in this device are color sensor TCS34725, pH meter sensor module SKU-016 and DS18B20 temperature sensor, the calculation of the amount of fluid that must be entered automatically from the patient's body weight input. The programming uses Arduino Nano as the main controller with a 128x64 graphic LCD. From the testing that has been done, it is known that the percentage error in the module is 3.5%, which means that it is still in the tolerance value because the tolerance limit is 5%, for the sensitivity test results get a value of 60% and specificity of 70%. Thus, it shows that the device is feasible and can be implemented as a dehydration detection device that is carried out independently at home.

Sistem Pendeteksi Keasaman dan Warna Urine sebagai Indikasi Dini Dehidrasi

“…Data kemudian diolah dengan program python untuk mencari nilai U dan Y sebagai penentu klasifikasi dehidrasi. Peneliti [12][13] melakukan pengukuran tingkat dehidrasi dengan memanfaatkan sensor warna, atau pH meter.…”

Enhancement Drip Dose Infusion Accuracy Based on Optocoupler and Microcontroller Sensor

“…Such as cases of bleeding, dehydration, diarrhea, burns, certain diseases, etc. [1]- [4] To overcome these cases, a fluid therapy is needed. Fluid therapy itself has the meaning of an act of giving water and electrolytes with or without nutrients.…”

“…It is feared that the drip rate may change due to obstruction or other reasons. [4], [23]- [25] There are so many innovations related to fluid therapy, KK Thariyan using 3 sensors but the accuracy level is unknown [23]. Hanna Firdaus, make a central infusion monitor system with volume and droplet detection parameters per minute using the TCRT-5000 sensor with an error of 4% at a flow rate of 30 ml/s [2].…”

Prototipe Light Meter Fotografi Studio Menggunakan Mikrokontroler ATMega328 Berbasis Sensor Cahaya dan Warna

“…Modul Sensor Cahaya TSL2561 Pada Gambar 5 adalah perankat modul sensor cahaya TSL2561 c. Sensor Warna RGB TCS34725Modul sensor warna GY-33 TCS 34725 merupakan sensor penginderaan warna yang memiliki elemen penginderaan cahaya RGB dan Clear. Sensor ini dilengkapi dengan filter blok IR, on-chip terintegrasi dan dilokalisasi ke foto sensor warna, meminimalkan komponen spektrum IR dari cahaya yang masuk dan memungkinkan pengukuran warna dilakukan secara akurat[17].…”
