Abstract
A breathing apparatus including a case containing a chemical for generating oxygen and a monitoring circuit in the case is disclosed. The monitoring circuit includes multiple sensors to that sense parameters within the case relevant to an operational status of the breathing apparatus, and a controller to receive signals from the sensors and to produce an output signal indicating the operational status of the breathing apparatus. A method for monitoring a breathing apparatus is also disclosed. The method includes using multiple sensors within a case of a breathing apparatus to sense parameters relevant to an operational status of the breathing apparatus, and processing signals from the sensors to produce an output signal representative of the operational status of the breathing apparatus. The sensors may include humidity, impact, pressure and temperature sensors.
