Implementation of Geofencing for Monitoring People under Home Quarantine

Coronavirus Disease (COVID-19) is an infectious disease caused by SARS-CoV-2, a newly discovered coronavirus. Infected people experience mild symptoms such as colds, which would lead to severe respiratory-related diseases that weaken the entire body. As the virus can be transmitted primarily through direct contact with an infected person or by touching surfaces and objects contaminated by respiratory droplets, it is critical to control and cut the transmission routes by exposing individuals under quarantine. In this study, the researchers developed an Arduino-based ankle tracker, associated with an application as the GUI, to implement geofencing to monitor people under home quarantine. The ankle tracker acts as the trigger being monitored within a geofence, a circular virtual perimeter. The system was designed to have a 95% confidence level to filter out inaccurate GNSS location data. It will only accept data that is highly accurate which depends on the PDOP value. The Geo-mapping accuracy of the tracker device was tested and presented in this study.
