7.1.4 Explain the relationship between a sensor, the processor and an output transducer.

1. Sensors get analogue information
2. AD (analogue-digital) transducer converts the analogue data to electrical and digital impulses
3. The microprocessor conducts task based on that data
4. The DA (digital-analogue) transducer converts the digital data to analogue data
5. The actuator shows the analogue data to the user
