Handwashing Machine By Fog Disinfection To Save Water

Electronics and Communication Engineering

Since the start of the COVID-19 pandemic, it is recommended to wash your hands several times a day. The problem of irrational water use will cause more problems than the pandemic itself. To solve this problem, we have developed a system that allows you to wash your hands without using more than 96% water than the traditional water usage. When the faucet is open, only 20-40% of the water touches the skin and the rest of the water is simply wasted. Our proposed device goes ahead even further and plays important role to save water. The machine is integrated with a tank and it is filled with water with a safe herbal disinfectant. When the user inserts his hands into the system, the water mist system activates automatically, converting the water in the reservoir into mist leading to the chamber. After exposing the hands to water mist for 10-15 seconds, the user hands gets sanitized. The machine consists of two IR sensors that detects the users hand and activates the Ultrasonic Piezoelectric Humidifier which is driven by nodeMCU ESP8266.Thus, the machine we offer can be sterilized by hand washing while saving a lot of water.
