When someone approaches, they will greet you with a beautiful female voice and send a welcome speech: Hello! Welcome or other music. People go away and come in again, and say to you again: Hello! welcome! The principle of light perception is that the sound is made after the light changes, so it is not necessarily the sound of people passing by, as long as the light changes. There needs to be sufficient and stable light in the store. If the light changes frequently, there will be false alarms. Insufficient light will affect the sensing distance. If the above light conditions are not met, the store owner recommends buying an infrared sensor (not affected by light changes)
