Design of Heart Rate, Oxygen Saturation, and Temperature Monitoring System for Covid-19 Patient Based on Internet of Things (IoT)

Abstract

Instruments for measuring pulse rate, oxygen saturation, and body temperature for Covid-19 patients have been designed using the MAX30100 sensor and the Internet of Things (IoT)-based MLX90614 sensor. The MAX30100 sensor is used to measure pulse rate and oxygen saturation. A non-contact MLX90614 sensor is used to monitor body temperature, with an ultrasonic sensor used to set the maximum distance between the sensor and the object. The measurement results were transferred to the database via the ESP8266 MCU node's Wi-Fi communication line. The stored data can be accessed via a web browser. Compared to the oximeter, the MAX30100 sensor has an average error rate of 1.027% for pulse measurement and 0% for oxygen saturation. The MLX90614 sensor has a 0.42% average error rate when it was compared to the thermo-gun.Thus, the measuring device can function properly and is feasible to use. Furthermore, because there is no direct contact between the human body and the sensor, the instrument can prevent Covid-19 transmission.

Inovasi Pulse Oximeter dengan Sumber Cahaya LED Merah dan Inframerah yang Dilengkapi Suhu Tubuh Menggunakan Sensor MLX90614 Berbasis IoT

“…Buzzer akan berbunyi saat nilai tidak berada dalam batas normal. Pengembangan alat yang dibuat Rahmawarni telah dilakukan oleh Costrada et al (2022) dengan mendesain sistem monitoring denyut nadi, saturasi oksigen dan suhu tubuh untuk pasien Covid-19 berbasis IoT. Penelitian ini juga menggunakan sensor MAX30100 untuk mendeteksi denyut nadi dan saturasi oksigen serta sensor MLX90614 untuk mendeteksi suhu tubuh.…”

Monitoring SpO2, BPM, and Temperature on Smartband with Data Sending Using IoT Android Display

“…However, the use of electrocardiograms and thermometers used by medical personnel in hospitals or health centers is still being done repeatedly and requires concentration to get an accurate value, given the changes in heart rate and body temperature that keep on changing. This of course raises several problems, including the time it takes for medical personnel to determine the results of the diagnosis, the increase in patients will increase the burden on doctors in conducting patient examinations, and the amount of costs that must be incurred by the manager in completing the equipment for each medical personnel [24] [25] .…”

Design and Implementation of a Healthcare Monitoring System Based on LoRa

“…When COVID-19 symptoms manifest, the patient's body temperature rises to greater than 38°C. To detect early lung damage in patients with Covid-19 and stop it from progressing, a monitoring device for the patient's oxygen saturation, heart rate, and body temperature is required [15]. The MAX30100, MAX30102, and MAX30105 sensors have been employed in several investigations as heart rate and oxygen saturation sensors.…”

“…The MAX30100, MAX30102, and MAX30105 sensors have been employed in several investigations as heart rate and oxygen saturation sensors. These sensors operate on the reflectance principle, where the light source and detector are located on the same side, allowing measurements to be made on different body sections [11,15]. Temperature sensors must be included as well so that the equipment may be used to identify early signs of Covid-19 patients.…”

“…The MLX90614 sensor was chosen as a non-contact body temperature sensor to prevent Covid-19 transmission. Much research has employed DS18B20 and LM35 sensors as temperature sensors [15][16][17]. A measuring device based on Lora's contact technology has been created for heart rate, oxygen saturation, and body temperature based on the above-mentioned biomarkers.…”
