About Automatic Hand washing System.

My project is a simple basic system but it can useful to encourage the people with proper hand washing habbits although such kinds of systems exist in the markets.Moreover, it can solve hygiene problem as we usually neglect to practice in our daily life.People still use manual soap bottles or bar soaps which require contact and may spread germs, and time consuming too.You will see an user interaction as i will be developing a system where the wash room user is introduced to the system and making them to wash hands.

This system will encourage hand hygiene, prevents spread of germs, teaches clean habbits early especially for children, safe and easy to use with the emerging technlogy.

How my Hand washing system works?

I will choose to fix my hand washing system in the washroom.It will consists of a small box at washroom cabin having a PIR sensor,speaker,DF player and XIAO ESP32C3.While the soap dispenser bottle will be at the wash basin with distance sensor, water pump with a 3V relay module and XIAO ESP32C3.

When the user enters the washroom, the motion sensor detects entering to the wash cabin and first it will play welcome sound followed by song play while doing the toilet.When he/she is done with toilet, the morion sensor will observe and directs to wash hand from the soap dispenser.If the person do not go to wash hand then it will play alarming sound, letting the user use the soap dispenser.The distance sensor at soap dispenser will trigger the water pump to dispense required amount of soap.The thank you sound plays from the washroom cabin box after using the soap to wash hand.
