“This project is a prototype of a smart home system using raspberry pi pico.
Evil can stalk anyone, and wherever we are. Even in the home, crime can happen. Even if the house is locked at night, and given CCTV, it will not be able to guarantee everything is safe. Therefore, there is a need for a danger alarm to notify the homeowner if the house or room is entered by strangers or thieves. And he made this warning alarm to anticipate the danger of thieves or strangers who will enter the house or room.”
