A transducer in IoT typically converts physical signals to electrical signals.

In IoT, a transducer is a device that changes energy from one form to another. The most common role in data gathering is a sensor, which takes a physical quantity—like temperature, light, sound, or pressure—and converts it into an electrical signal that a microcontroller or processor can read. That direct conversion from the physical world to an electrical signal is why the statement is true in typical IoT contexts. There are transducers that do the opposite, such as actuators that convert electrical signals back into physical action (motion, force, or light), but for the everyday data path in IoT, sensors doing physical-to-electrical conversion are the standard example.
