The COVID19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID19), caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV2). The outbreak was first identified in December 2019 in Wuhan, China. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30th January 2020 and a pandemic on 11th March. The first case of the virus was confirmed in Sri Lanka on 27th January 2020, after a 44-year-old Chinese woman from Hubei Province in China was admitted to the National Institute of Infection Diseases. As of 16 August 2020, 2,890 confirmed cases have been reported in the country with 11 deaths. On 3rd March 2020, the first reported case involving a Sri Lankan origin outside Sri Lanka was reported in Italy. As of 23 March, forty-five quarantine centers have been built in the country by the Sri Lanka Army as a preventive measure to tackle the coronavirus pandemic. Nearly 3,500 people have been under quarantine in 45 quarantine centers which also include 31 foreigners from 14 countries. As of 25 March 2020, Sri Lankan authorities have tracked down over 14,000 people who had contacted the identified patients and had ordered self-quarantine for such people.
When putting a person under self-quarantine, medical officers and the police will come to the house where that person lives and advise that person not to go out. Even though the person under self-quarantine is advised not to go out the medical officers cannot be guaranteed that the person will not go out because they do not have a proper method to monitor the people under self-quarantine. If people under self-quarantine do not obey the rules and go out of the home and interact with other people, there will be a risk of exposing other people to the virus if those self-quarantined people are infected
The device is designed to be used by the medical authorities to track if the person who is under quarantine (wearing the device) is breaking the law and also to track his/her health; to check if he/she would implementing the symptops of the illness using thier smart phone and reduce the spreading of the virus as much as possible.
As a solution we present a band which is wearable by the person who are unde quarantine such that the corresponding data such as body temperaure, the movements of the person and the location will be gathered and send to the mobile app which is used by the medical authority. so they can track and moniter the person keeping their distance and as well as improve the quality of their job.
The node mcu works with 3.3 v so we supply power of 7.4v(power supply) from the betteries to the Vin pin of the node mcu.
since the node mcu has an in built voltage regulator we can supply a voltage range of 7-12Vs to Vin
