Cute smoking alarm

Swallowing smoke and spitting fog in public places, the people next to them cover their noses and turn their heads, but few people go up to remind them to stop. Don't dare. If that guy gets mad, it's gonna be bad. But we can't have that smoke hanging over our air and affecting the quality of our oxygen. Get a stand-in first. ok, No smoking alarm system then. Even though it looks not threatening, you will never forget it after trying it. Install this smoking alarm in those public places, but when someone smokes, it will "smell" the smoke and then light up the "No smoking" lamp. If you don't repent of its warning, it will get angry. Immediately it will emit a siren louder than the sound of a police car, and then the eyes of friends in all directions will focus on the cigarette in your hand (this kind of turning back is not easy to enjoy oh, it will be indigestion) At this time, the big brother who smokes should be a little uncomfortable, find a hole first. What an idea for the benefit of mankind.
