1. An evacuation system, comprising:
a compressed fluid source comprising an external surface;
an evacuation slide coupled to the compressed fluid source;
a surface acoustic wave (SAW) sensor coupled to the external surface of the compressed fluid source;
a transceiver;
a display device; and
a controller in electrical communication with the transceiver, the controller configured to:
determine a pressure in the compressed fluid source based on data received from the SAW sensor,
compare the pressure to a pressure threshold,
generate an alert in response to the pressure being less than the pressure threshold, and
sending the alert to the display device.
