Hand free sanitizer diy

thingiverse

We're introducing a hand-free sanitizer that leverages servos to prevent direct contact with the bottle. As a test case, I've utilized a Dettol 200ml container, which can be easily swapped out for various models and reused. This design taps into an ultrasonic sensor as input and a micro servo as output to activate the sanitizer efficiently. A compact gear mechanism is employed to regulate the sanitizer cap's movement, ensuring just the right amount of liquid dispenses with each use. The system relies on an Arduino Mega controller for seamless operation.
