a device that detects smoke and gives a warning
例子
The landlord installed a new smoke detector in the rental apartment.
The smoke detector requires proper maintenance to ensure it functions correctly.
The smoke detector is equipped with a loud alarm to warn residents of a potential fire.
The smoke detector is sensitive to smoke and can detect fires at an early stage.
I forgot to replace the battery in the smoke detector, so it wasn't working properly.
