In the very beginning of 2020, covid-19 exploded all over the world and disturbed our lifestyle. In these tragic conditions, alcohol-based hand sanitizers play an important role and become a vital fluid nowadays though they need to be used properly. Touching alcohol containers or hand sanitizers with infected hands can spread the virus to the next person. We propose to build an automatic hand sanitizer dispenser that uses IR sensors to detect the presence of a hand and activates a pump or solenoid to pour the liquid on the hand. The intention was to find the cheapest and easiest solution and design a circuit & manufacture the same in India. The dispenser is contactless and will spray alcohol-based hand rub sanitizer for sanitization of hands while entering buildings like Hospitals, Office complexes, Malls, etc. This is a mist-based dispenser, to optimize the consumption of sanitizer. Whereas in normal usage, we use 20-30 ml of sanitizer for one operation, this sanitizer does the same job by dispensing just 5- 6ml of sanitizer in mist form over a long period.
