An acrylic based automatic hand sanitizer machine
Why hand sanitizer machines are used today
An automatic hand sanitizer dispenser is a device dispensing a controlled amount of sanitizer. They are often used in conjunction with automatic faucets in public restrooms. They help conserve the amount of sanitizer used and stem infectious disease transmission.

A brief note on working :
The ultrasonic sensors of the automatic hand sanitizer dispenser detect the obstacle in front of it. When hands are placed in the front ultrasonic sensor, the ultrasound quickly fluctuates. This fluctuation causes a voltage variation that can be detected by microcontroller such as arduino which then triggers the pump to activate and dispense the designated amount of sanitizer. Led is also triggered on and off with pump for indication.
