COVID-19 is a global pandemic afflicting our so ciety. We propose covloT, a novel Arduino-based automatic hand sanitizer dispenser, integrated with an oximeter, a heart rate monitor, a non-contact body temperature sensor, and voice assistant feedback. This system can be deployed as an end-to end COVID patient monitoring system and also for automated sanitization. The system was tested on 100 people to evaluate its performance. The mean absolute error and root mean square error values were found to be 0. 79 and 1.03 for the oximeter, 1.22 and 0.70 for the heart rate monitor and 1.07 and 1.28 for the body temperature monitor, respectively, compared to the industry-standard devices. These low error values indicate the high accuracy of our proposed system. We believe this is the first low-cost integrated patient monitoring and sanitization system with vocal feedback, to increase accessibility and ultimately helps combat the virus.
