Implementation of Oxygen Saturation Sensor Data Acquisition Based on Bluetooth Low Energy Protocol

Abstract

Sensor data acquisition is used to obtain sensor data from IoT devices that already provide the required sensor data. To acquire sensor data, we can use Bluetooth Low Energy (BLE) protocol. This data acquisition aims to process further data which will later be sent to the server. Bluetooth Low Energy (BLE) has an architecture consisting of sensors, gateways, and data centers, but with this architecture, there are several weaknesses, namely the failure when sending data to the data center due to not being connected to internet network and data redundancy at the time of data delivery is done. The proposed solution to solve this problem is to create a system that can acquire sensor data using the Bluetooth Low Energy (BLE) protocol with use a store and forward mechanism and checking data redundancy. The proposed system will be implemented using sensors from IoT devices, the gateway used is Android devices, and using the Bluetooth Low Energy protocol to acquire data from sensors. Then the data will be sent to the cloud or server. The results of the test give the results of the system being successfully implemented and IoT devices can be connected to the gateway with a maximum distance of 10 meters. Then when the system stores, for every minute there is an increase in data of 4 kb. Then there is no data redundancy in the system.

Smartband for Heartbeat and Oxygen Saturation Monitoring with Critical Warning to Paramedic via IoT

“…People infected with COVID-19 will generally experience hypoxia, which causes shortness of breath. If treated too late, the patient will experience respiratory failure, organ failure, and eventually death [17] [18]. Implementation of wearable devices for continuous monitoring is expected to influence health care in several ways [19].…”
