In public places, squeezing the bottle of hand sanitizer is very unsanitary. At the same time, the quality of some customers leads to the waste of squeezing too much hand sanitizer. At home, we often find the bottle of hand sanitizer and the button of squeezing hand sanitizer is dirty. A recent invention in Canada solved this problem.
This artifact is called intelligent soap sensor. The magic of this artifact is that it can automatically squeeze out the hand sanitizer only by infrared induction, and the output is accurate, 2 ml is not much and not much, which is both economical and hygienic.
