The overall goal of team SAFE-T is to assist emergency personnel without interfering with their abilities to perform their important work. For our project we utilize a series of sensors connected to a firefighter’s equipment to monitor vital safety information including temperature levels inside and outside of the suit, heart rate, and oxygen tank levels. Using the output signals from these sensors, we can transmit the data via 2.4 GHz radio wave to a central command center with a portable android device that will display the resulting data within logical GUI that can be easily deciphered by the fire chief. This will ultimately increase the level safety for firefighters within a building by allowing real time data to be conveyed accurately without causing distraction to the firefighter.
