Suppose a film of oil builds up on the shaft, diffusing light from the reflective strip or increasing the reflectivity of the black part? These types of questions have to be answered. In some cases, you may have to add hardware and/or software to detect unusual conditions. In the example already mentioned, where a reflective sensor generated excessive interrupts, the software might have a timer that keeps track of the time between interrupts. If the sensor ISR is exited and immediately reentered, the ISR could disable the interrupt and set a flag to tell the rest of the system that something is wrong. Open Sensors In systems where safety is an issue, be sure that a failed sensor doesn’t cause the system to operate in an unsafe manner. A typical example would be a 64 Analog Interfacing to Embedded Microprocessors safety hood that must be closed before the machine can start. The idea is that
