IT Features• A Process is monitored by Sensors• Sensors are usually connected to an Interface that is connected

to a computer• Often signals from Analogue sensors are converted to Digital

signals (ADC) so that they can be understood by the computer• The computer usually takes readings at regular logging intervals• A logging period is usually set• Readings are recorded and usually Saved onto Backing Storage• Data collected is Analysed – e.g. A graph may be plotted to show

the results

AdvantagesFully Automated – humans not needed for measurement (24/7 possible)Greater accuracy of measurementTime Intervals and Period of logging may be variedMaybe performed remotely and results sent to a computerResults are in Real Time so may be acted upon immediatelyData maybe constantly analysed and charts created

Disadvantages

Dependant on a form of electricity and electrical hardwareSome training neededCertain things for patients can only be monitored by humans, such as skin color or swelling in a patient's bodyInitial costs may be expensive
