What is a transducer?

A transducer is an electronic device that transforms energy from one form into another. You’ll find them everywhere—microphones capturing sound, loudspeakers projecting it, thermometers measuring temperature, and sensors detecting pressure and position. Even devices like photocells, LEDs, and ordinary light bulbs function as transducers, though they’re not always recognized as such.
 
The device known as a transducer transforms one kind of energy to another form. The device operates in sensors and microphones and speakers to transform physical signals into electrical form or transform electrical signals into physical form
 
A transducer is a device that converts one form of energy into another, commonly used in measurement and control systems. Examples include microphones (convert sound to electrical signals) and speakers (convert electrical signals to sound). Transducers are widely used in medical, industrial, and consumer applications, such as ultrasound machines, pressure sensors, and touchscreens.
