ABSTRACT:
The present invention provides a sensing system for monitoring an environment that includes at least two sensors and a control unit in communication with the sensors. At least one of the sensors is active providing an output signal to the control unit indicative of a sensed property, while the other sensor(s) is inactive and protected from the environment. During operation of the sensing system, if it is determined that the performance of the active sensor is abnormal, the inactive sensor is activated. Subsequently, the output signal of the abnormal sensor is ignored and the control unit utilizes an output signal of the previously inactive, but now active, sensor.
