In my country now only we know about hand sanitizer and hand wash. But this corona virus infect even we touch others possession.
This setup dispenses the hand sanitizer lotion or washer while the user place their palm before the obstacle sensor
It was built by a microcontroller, obstacle sensor, servo motor and power bank. A string is attached the servo motor knob and the other side is attached with one bolt. You can adjust the height by loose the string.
sure it will be use for schools, rural hospitals etc...
Next i am going to attach UV sterlizer and UV treat water dispenser
