Vitaband: IoT-Driven Health Monitoring System for Home Quarantine COVID-19 Patient Using LoRaWAN

Technological advancements in medical field gave birth to smart watches, handheld devices that can read your vital signs real-time. However, home quarantined COVID-19 patients, even with the help of smartwatches, are still needed to be monitored physically by health practitioners, therefore posing a threat of transmission of the virus. This paved the way to the investigation of designing a wearable device that read health vital statistics and the location of home quarantined patients and a system that will remotely monitor it. Thus, this work developed Vitaband, a health-monitoring system made up of a node, gateway, and a web application. The node consists of sensors – pulse meter, oximeter, IR sensor and GPS module – that will read the vital signs of the patient and display it through an OLED screen. Two Raspberry Pico Pi microcontrollers will process the data gathered by these sensors and send them to the gateway through the Lora module. The gateway then, housing the ESP32 microcontroller, will connect to the internet and transmit the received data to the MongoDB database. The web application finally, which is programmed using REACT framework, shall display the data for remote monitoring. Vitaband is tested and evaluated using the ISO/IEC 25010 model. Results revealed that Vitaband received an overall rating of Very Satisfactory from the Bulacan State University Nursing student during their training as the respondents and Excellent from medical professionals which are registered nurses and barangay health workers, respectively.
