The COVID-19 pandemic has had an effect on human life in many different fields. There have been several attempts to stop the virus from spreading, including working from home, avoiding social gatherings, and practicing hand hygiene. Since the COVID-19 virus can spread through touch and contact, there are WHO recommendations to regularly wash or sanitize hands to lower the risk of infection. Sanitizer storage and dispensing from the bottle would both require manual intervention. And the majority of the hand sanitizers that are currently on the market don't work automatically. In order to lower the risk from contact, this article intends to create an automatic hand sanitizer that is used in hospitals, workplaces, offices, schools, and much more.Here, the system uses an ultrasonic sensor to detect proximity and sends a signal to the microcontroller (Arduino UNO). The controller activates the solenoid valve and pump after processing the sensor data. As a result, a mist nozzle is used to disperse the sanitizing liquid. |
