Design and Development of Breathing Air Level Transmitter by using Arduino

Firefighters risk their own lives while performing their required tasks, which
is rescuing under dangerous and hazardous environment. There have been numerous
amount of cases in which the firefighters themselves were not able to survive and
died before they even managed to carry out their duties. Therefore, a mechanism or
system to monitor the condition of a firefighter on duty is very much needed and
must be implemented. This system should be able to allow another personnel who is
not on duty to monitor the condition of the firefighter throughout the whole period
when he or she is on duty under dangerous environment. Through this, fast and
immediate actions can be taken whenever there is an emergency or accident that
occur and thus fatalities involving firefighters while carrying out their mission can be
prevented. With the digital air flow sensor used, it will be able to transmit real time
data to the monitoring system and indicate the control centre whenever the oxygen
level in the tank is low.
