Abstract:
In this project, an automatic sanitizing mist machine is non-contact, alcohol based sanitizer solution which finds it’s use in hospitals, offices, workplaces, schools and any other premise. Alcohol is basically a solvent and also a very good disinfectant if we compare it to liquid soap. Also, it does not need water to wash off since it is volatile and vaporizes instantly. It is also proven that more than 70% of alcohol can kill Coronavirus in hands. Here , an ultra-sonic sensor is used to sense any motion near it while Arduino is used as microcontroller. As a result, a mist form of sanitizing solution is sprayed out. The counter on the other hand is bi-directional which means any motion that moves within 9cm from the other ultra-sonic sensor is detected, the LCD display number will increase by 1 while any motion more than 9cm will be counted as a person leaving. So, the number displayed on the LCD will be subtracted by 1. This will help workers and owner of the premise make sure that the place is not crowded and safe for any customer to enter the building
