A transducer is a device that converts one form of energy into another, usually for the purpose of measuring or exchanging information. There are several varieties of transducers:
- Photoelectric transducers convert electrical energy to light, or vice versa.
- Ultrasonic transducers convert mechanical waves (sound) into electrical signals.
- Antennas convert radio waves to electrical signals.
- Electrochemical transducers convert chemical composition information to electrical signals.
- Pressure transducers convert a pressure reading to an electrical signal.
