What is the difference between a transducer and a sensor? Before we know it, we need to know what is a transducer? And what is a sensor?
What is a sensor?
A sensor is a device that responds to an input-type object from a physical environment. Specific inputs For example; Light, Heat, Motion, Moisture, Pressure, or any other environmental factor can be.
What is a transducer?
A transducer is an electronic device that converts energy from one position to another. For example; a microphone, loudspeaker, thermometer, pressure sensor, antenna, etc.

Discussed the significant differences between sensors and transducers.
| Sensor | Transducer |
|---|---|
| (i) It can only detect the input of an object. | (i) It converts one type of energy into another. |
| (ii) A sensing element used in the input of the sensor control system. | (ii) Transducer instrumentation and control, used in system inputs and outputs. |
| (iii) Sensors are usually smaller in size and carry less energy. | (iii) The size of the transducer is small or large and carries more energy. |
| (iv) Does not change any shape. | (iv) Changes shape. |
| (v) It is the primary element. | (v) It is a secondary device. |
| (vi) The sensor always has an electrical output. | (vi) The transducer does not always have electrical output. |
| (vii) All sensors are known as transducers. | (vii) Not all transducer sensors. |
| (viii) Examples Proximity sensor, light sensor, Barometer etc. | (viii) Examples: Microphones. loudspeakers. thermometers, antenna etc. |
