Question

what is the difference between atransducer and asensor and detectors

Answer 1

A transducer is an electronic device that converts energy from one form to another. Common examples include microphones, loudspeakers.Note that any device which is able convert one form of energy into another form is called as a transducer. For example, even a speaker can be called as a transducer as it converts electrical signal to pressure waves (sound).

Sensor is a device that responds to a physical stimulus (such as heat, light, sound, pressure, magnetism, or a particular motion) and transmits a resulting impulse (as for measurement or operating a control)

Detector is A device capable of registering a specific substance or physical phenomenon, and that optionally sounds an alarm or triggers a warning.

The sensor senses the physical change across the surrounding whereas the transducer transforms the one form of energy into another.

The primary function of the sensor is to sense the physical changes, whereas the transducer converts the physical quantities into an electrical signal.

The accelerometer, barometer, gyroscope are the examples of the sensors whereas the thermistor, and thermocouple is the examples of the transducer.

Sensor and detector are often used synonymsly.
