What is the main function of a transducer?

The main function of a transducer is to convert one form of energy to another. Transducers are essential components in various applications, as they enable the transformation of physical phenomena into readable signals or vice versa. For example, a temperature transducer might convert thermal energy into electrical energy that can be measured by a temperature gauge. Similarly, in audio equipment, sound waves (mechanical energy) are transformed into electrical signals that the system can process. This ability to change the energy form makes transducers crucial for interfacing different systems, such as sensors and control units, ensuring accurate data generation and interpretation.
