Abstract:
During these times, the Covid-19 pandemic has disrupted our way of life. There has been a need to come up with innovative ideas that can help combat its spread. As the disease is spread through human contacts and touching of surfaces. It is important to come up with ways that general hygiene can be more enhanced. One of the disease symptoms is the abnormally high temperature which has made it necessary for person temperatures to be taken at the entrances to malls, hospitals, schools etcetera in the effort to reduce the spread. In this line, our solution is an innovative way of detecting, reducing the spread, and minimizing contacts as much as possible. Our project is composed of two devices working in combination. Both devices will be designed and then implemented, then combined into a Contactless Infrared (IR) thermometer with hand sanitizer dispenser. The contactless IR thermometer uses MLX90614 to take the temperature readings and display them on OLED display. If the read temperature is within the normal range, the person can then place hand at and not touching the nozzle of the sanitizer dispenser which then dispenses automatically. If the person's temperature is above the normal, 37.5-degree celsius, the devices buzz a sound and give a Red indicator alert for further action to be taken. The two devices are controlled centrally using the ATMEGA 328p microcontroller.
