To amplify electrical signals
To control the power supply in a system
Which of the following is a type of transducer?
Microcontroller
Thermocouple
Motor
Relay
What is the main difference between a sensor and a transducer?
A sensor converts physical quantities into electrical signals, while a transducer converts one form of energy into another
A transducer processes data, while a sensor measures temperature only
A sensor stores data, while a transducer communicates with actuators
A transducer only detects motion, while a sensor detects pressure
