Intelligent sensor

Summary
An intelligent sensor is a sensor that takes some predefined action when it senses the appropriate input (light, heat, sound, motion, touch, etc.). Description The sensor has to do the following tasks: *Give a digital signal. *Be able to communicate the signal. *Be able to execute logical functions and instructions. Elements of intelligent sensors
  • Primary sensing element
  • Excitation control
  • Amplification
  • Analogue filtering
  • Data conversion
  • Compensation
  • Digital information processing
  • Digital communication processing
Technical capacities Because the tasks are performed by microprocessors, any gadget which mixes a sensor and a microprocessor is usually called an intelligent sensor. To qualify as an intelligent sensor, the sensor and processor must be part of the same physical unit. A sensor whose only function is to detect and send an unprocessed signal to an external system which performs some action is not considered intelligent. Ub
