Maintaining hand hygiene has been a crucial thing for reducing the spread of infectious diseases. The hand hygiene recommendations are believed to play an important role in decreasing the risk of infections. In this pandemic, sanitization has become a major and essential practice for human life. But the use of common public sanitizer bottle may become dangerous. The sanitizer bottle may act as parasite to carry virus from an infected person by pressing the bottle trigger. That may increase the chance of spreading virus. We can solve this by including automation through Embedded Systems. Automation prevents the common contact with people. We can achieve this automation using a motor pump with controller or a servo motor. Here in this report, we are proposing an automatic hand sanitizer using an Ultrasonic sensor, Servo motor and Arduino-uno and know about the components. This automatic sanitizer dispenser machine is automated, contact less, alcohol based sanitizer dispenser, which catches its use in almost all public places like schools, offices, hospitals, work places, and much more. Alcohol is basically a very good antiseptic when compared to liquid or washing soap; also it does not require water to wash off since it is volatile and vaporizes instantly after having on hands. Here, an ultrasonic sensor generally senses anything which is placed near to it. Likewise it also senses the human hand placed near it, the sensed information will be sent to the microcontroller here it is Arduino-uno, this controller process the data and turn on the pump to pump out the hand sanitize liquid.
