Research on the Design of a Sensor-based Firefighters Safety Guardian System

In order to ensure the safety of firefighters who have deepened the fire on the fire, a firefighter security guard system based on sensor technology was designed. This device can monitor the live signs of firefighters and harmful gases and upload firefighter signs and harmful gas concentrations data to the system to view and control. The detection data exceeds the preset threshold to send an early warning signal to the firefighters and the mobile terminal. By testing in different environments, the temperature, heart rate, and harmful gas concentration measured by the system are very accurate, and the changes in the concentration of harmful gases are very sensitive.
