Design and Implementation of Wi-Fi Enabled Contactless Electronic Stethoscope

The very initial diagnosis tool which most of the healthcare experts use is a stethoscope. This is an inevitable element in monitoring the bio-acoustic signals of patients by doctors. During the SARS CoV-2 pandemic situation, the conventional stethoscope generates a huge threatening to the physician's life as it creates a direct close contact with patients. A contactless tool is necessary in the present scenario and a similar one is proposed in this paper. The design and hardware implementation of a Wi-Fi enabled stethoscope which is having both transmitter module (patient side) and receiver module (physician side) presented. MAX9814 microphone captures and processes the acoustic sounds including cardiac auscultation, sends the data in MQTT packets through ESP32 kit. The system is designed in such a way that multiple users in receiver end can visualize the live auscultation plots, body temperature plot and listen to the bio-acoustic sounds. A mobile app is associated with system to monitor the patient's health information. Raspberry Pi unit in the receiver module, controls the operations in receiver module. The results obtained using the proposed system compared with real-time data and verified the performance. © 2022 IEEE.

Gate Access Control using Face Mask Detection and Temperature

For the prevention and spread of COVID-19, people are currently used to screen temperature and identify masks in public spaces. All scanning entries include temperature testing equipment;however, manual temperature scanning has some limitations. Temperature scanners aren't well-known among personnel. Despite higher temperature readings or the lack of masks, people are frequently given admission. Manual scanning equipment is useless in huge groups. As a result, an automated system that monitors temperature and mask is required. To address this problem, a completely automated temperature scanner and entry provider system has been presented. A contactless temperature scanning and a camera are used in the system to take images. The scanner is attached to a gate-like mechanism that blocks admission if a feverishness or no mask is detected. The gadget employs a temperature sensor and camera attached to a Raspberry Pi system to monitor the entire operation. The major goal of this article is to automate the entire COVID scanning procedure to reduce the possibility of COVID-19 spreading in densely populated areas like malls, schools, and universities © 2022 IEEE.
