ABSTRACT
Body temperature is a significant vital sign that can provide great insight as to the state of health of a person. Nowadays, body temperatures are monitored as often as a precaution for the COVID-19 virus. This can be achieved with the use of wearables, which can be non-invasive and convenient for anybody to use. This study aims to design and construct a wearable that can accurately detect the body temperature of a person using the MLX90614 sensor as well as an I2C enabled LCD to allow the user to monitor their temperature at a moment's notice. © 2023 IEEE.
ABSTRACT
The entire humankind is combating the COVID-19 pandemic since the onset of 2020. The increase in the cases has triggered an alarming situation all over the world. Doctors and hospital staff are working overtime in the COVID wards by putting their lives at risk. As the health line workers are in immediate contact with the patients, it causes a high risk of spreading the infection among them. To avoid immediate contact of the medical personnel with the patients, the work presented in this paper aims at devising wireless sensor network (WSN)-based COVID-19 patient health monitoring system, which is enabled with IoT and is useful in evaluating the patients, keeping a check on their vital/ health status without coming in contact with them, and eventually creating a feasible method of sending information related to the health of patients to the health staff. The doctors/nurses can keep an eye on the health stats and keep a check on the overall condition of the patients. In case hospital beds are not available, this system can also be used when the patient is home quarantined. The health personnel can take necessary action according to the parameters through mobile phone/desktop. The medical personnel may check these parameters through mobile phone or desktop and may take necessary action accordingly. Thus, the health monitoring system proposed in this paper helps monitor the data of patients remotely, and this decreases the need for contact between the health line workers and patients. This further lessens the possibility of infecting them. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
ABSTRACT
In this paper we propose the use of secure contactless Electronic Voting Machine(EVM). We used a Radio Frequency Identification(RFID) reader to authenticate the voter's identity, and Infrared(IR) sensors to implement contact-less voting to curb the spread of Covid-19. Significant components used are Arduino Uno, FC-51 Infrared Module, EM-18 RFID reader, keypad, and I2C PCF5874T for Liquid Crystal Display(LCD). The software used to program these components is Arduino IDE. This EVM ensures security in two ways - authorizing the identity of the voters before they are allowed to vote, as well as providing a contact-less experience for the voter. An extra layer of security is added, so that when the candidates and Election Commission are present and enter their respective passwords, only then can the results be accessed. © 2021 IEEE.
