Abstract
Systems and method for operating a sensor system located in, on or proximate to equipment. The sensor system is configured to: generate heat to ionize nearby flammable gasses such that the ionization products can be absorbed by a conductive sensing material which causes a change in resistance on the conductive sensing material; measuring the resistance on the sensor system to obtain an indication of a presence or absence of a flammable gas in a surrounding environment; assign a severity level to an operational state of the equipment based on the resistance measurement; select an action from a plurality of different actions based on the severity level which was assigned to the operational state of the equipment; and control operations of a robotic actuator or electronic device to perform the action.
