Description

Technical Field

[0001] The utility model relates to the technical field of fire data collection, in particular to a fire data collection device. Background Art

[0002] A smoke detector is a device used for fire warning. This detector can be used for fire warning and monitoring in homes, shopping malls, factories and other places to help people detect fires in time and take appropriate measures.
